how to calculate the xmldata? - apache-flex

i'm getting the xmldata from the httpservice (using cgi) and i have not set resultformat(it is coming as an object only),the xml data in this format
<root>
<employee name="xxx" age="xx" gender="xxx"/>
<employee name="xxx" age="xx" gender="xxx"/>
<employee name="xxx" age="xx" gender="xxx"/>
</root>
when i was tried to count the employee tag,i getting the problem, my code will like this:
var i:int=o;
for each(var obj:object in event.result.root.employee)
{
i++;
}
i getting the count as 3 but the problem it give the count as 3 when the coming data i.e)the xml data is
<root>
<employee name="xxx" age="xx" gender="xxx"/>
<root>
actually i want to count the number of employees tag not all subtag ,
i hope you may save my time
Thanks in advance..

Exist-db Add node with XQUERY

I have a listPers.xml (TEI List containing persons, obviously ) . I want to write a function to update the listPers.xml
My function looks like this:
declare function app:addPerson($node as node(), $model as map(*)) {
let $person := "<person xml:id=""><persName><forename>Albert</forename><surname>Test</surname></persName></person>"
let $list := doc(concat($config:app-root, '/resources/listPers_test.xml'))
return
update insert $person into $list//tei:listPerson
};
And the listPerson.xml
looks more or less like a typical list with person-entries
I have a tei:header (here omitted) followed by
<text>
<body>
<listPerson xml:id="person">
<person xml:id="abbadie_jacques">
<persName ref="http://d-nb.info/gnd/100002307">
<forename>Jacques</forename>
<surname>Abbadie</surname>
</persName>
<note>Prediger der französisch-reformierten Gemeinde in <rs type="place" ref="#berlin">Berlin</rs>
</note>
</person>
</body>
</text>
</TEI>
(sorry for ruining indentions, it's just an excerpt )
I do not get an error, which means that my app:addPerson should be fine, right?
I want the listPers_test to look like this:
<text>
<body>
<listPerson xml:id="person">
<person xml:id="abbadie_jacques">
<persName ref="http://d-nb.info/gnd/100002307">
<forename>Jacques</forename>
<surname>Abbadie</surname>
</persName>
<note>Prediger der französisch-reformierten Gemeinde in <rs type="place" ref="#berlin">Berlin</rs>
</note>
</person>
<!-- here comes the output that I wish to have :-) -->
<person xml:id=""><persName><forename>Albert</forename><surname>Test</surname></persName></person>
</body>
</text>
</TEI>
In the long run, I aim for an html-form that allows users to input names etc., where ids are generated using sth like
to-lowercase(concat($surname, "_", $forename));
But I will not get into my questions regarding forms and xquery, as I have barely done a quick Google-trip regarding html forms and xquery!
Can anyone hint me at why I do not get the listPers_test.xml file updated with the second value? :-)
All the best and thanks in advance to everyone,

Alright, I have a solution for anyone interested in it:
My first snippet $person:= ... contains a STRING, not an element.Changing the line
let $person := "<person xml:id=""><persName><forename>Albert</forename><surname>Test</surname></persName></person>"
to this one actually solves the issue:
let $person := <tei:person xml:id=""><persName><forename>Albert</forename><surname>Test</surname></persName></tei:person>

How to insert a constructed XML nodes in XQuery?

I want to insert a node using below code but if i will rerun the code i don't want my node to be repeated twice-
let $doc := fn:doc("abc.xml")
(: abc.xml looks like--
<root>
<value1>somevalue</value1>
<value2>somevalue</value2>
<value3>somevalue</value3>
<value4>somevalue</value4>
<value5>Australia</value5>
<value6>India</value6>
<value7>USA</value7>
<value8>somevalue</value8>
<value9>somevalue</value9>
<value10>somevalue</value10>
</root> :)
let $element := element Root{
element A{"A"},
element B{"B"},
element C{"C"},
element D{"D"},
element E{"E"}
}
let $doc := xdmp:node-insert-after(doc("abc.xml")//value4, $element)
return doc("abc.xml")
Whenever i am running this query my ELEMENT is getting inserted after value4 but i want that if i am running this multiple times then my element should get inserted only once and not multiple times.
Example- If i am running this 2 times-
Actual Output-
<root>
<value1>somevalue</value1>
<value2>somevalue</value2>
<value3>somevalue</value3>
<value4>somevalue</value4>
<Root>
<A>A</A>
<B>B</B>
<C>C</C>
<D>D</D>
<E>E</E>
</Root>
<Root>
<A>A</A>
<B>B</B>
<C>C</C>
<D>D</D>
<E>E</E>
</Root>
<value5>Australia</value5>
<value6>India</value6>
<value7>USA</value7>
<value8>somevalue</value8>
<value9>somevalue</value9>
<value10>somevalue</value10>
</root>
Expected Output-
<root>
<value1>somevalue</value1>
<value2>somevalue</value2>
<value3>somevalue</value3>
<value4>somevalue</value4>
<Root>
<A>A</A>
<B>B</B>
<C>C</C>
<D>D</D>
<E>E</E>
</Root>
<value5>Australia</value5>
<value6>India</value6>
<value7>USA</value7>
<value8>somevalue</value8>
<value9>somevalue</value9>
<value10>somevalue</value10>
</root>
Any Suggestions ??
Before inserting the node, check that it's not already there:
if (empty(child::Root)) then xdmp:update....
Note that you are using xdmp:node-insert-after -- this will do what the function name says (insert after) each time its called. As commented, you can conditionally call xdmp:node-update instead. Alternatively you can use xquery directly:
doc("file.xml" )/root ! <root>{ ./*[ . << ./value4] , $element , $a/value4, ./*[. >> ./value4] }</root>
Note: the "<<" operator compares "document order" (position not value)

Xquery html formatting

I'm new to Xquery. I have a requirement of rewriting the API response into custom xml format.
Input file format:
<root> <_1>
<dataType>
<name>XVar(Osmo [mOsmol/kg])</name>
<term>M185</term>
<type>XVar</type>
</dataType>
<values>305</values>
<values>335</values> </_1> <_2>
<dataType>
<name>XVar(DO (2) [%])</name>
<term>M199</term>
<type>XVar</type>
</dataType>
<values>12</values>
<values>33</values>
</_2> <_3>
<dataType>
<name>Maturity</name>
<type>Maturity</type>
</dataType>
<values>0</values>
<values>0.73600054</values>
</_3> </root>
Expected output:
<element> <XVar(Osmo [mOsmol/kg]> 305</XVar(Osmo [mOsmol/kg]>
<XVar(Osmo [mOsmol/kg]> 335</XVar(Osmo [mOsmol/kg]> <XVar(DO (2)[%])>
12</XVar(DO (2) [%])> <XVar(DO (2) [%])>33 </XVar(DO (2) [%])>
<Maturity>0</Maturity> <Maturity>0.73600054</Maturity> </element>
no of nodes (dataType -> name) will vary in each input file and also
Values will be dynamics .
currently using the below code.
let $input:= /root for $i in $input//values
return <element>
<name>{$i/../dataType/name/text()}</name> <values>{$i/text()} </values>
</element>
but all data are coming in and . my requirement is to
keep the node name as {$i/../dataType/name/text()} as values should
be {$i/text()} -
for the input file sample ideally there should be three different
nodes and its values.
Can any one help me on this?

XmlReader how to read or skip a specific child that does not always exist

I have a big XML file that I must read with XmlReader because it can not be loaded into memory. This XML is formatted in this way (is a reduced version):
<?xml version="1.0" encoding="windows-1252"?>
<Products>
<Product>
<Code>A14</Code>
<Name>Name1</Name>
<Manufacturer>
<Name>ManufacturerName</Name>
</Manufacturer>
<ProdCategories>
<ProdCategory>
<Code>015</Code>
<Name>ProdCategoryName</Name>
</ProdCategory>
</ProdCategories>
<Barcodes> <!-- note this line -->
</Barcodes>
</Product>
<Product>
<Code>A15</Code>
<Name>Name2</Name>
<Manufacturer>
<Name>ManufacturerName</Name>
</Manufacturer>
<ProdCategories>
<ProdCategory>
<Code>016</Code>
<Name>ProdCategoryName</Name>
</ProdCategory>
</ProdCategories>
<Barcodes>
<Barcode>
<Code>1234567890</Code> <!-- note this line -->
</Brcode>
</Barcodes>
</Product>
Note the <Barcode> <Code> elements: in the first <product> is missing.
This is the code that I use for read it and for put these data in a database:
XmlReader reader = XmlReader.Create("Products.xml");
reader.MoveToContent();
do
{
reader.ReadToFollowing("Code");
code = reader.ReadElementContentAsString();
reader.ReadToFollowing("Name");
Name = reader.ReadElementContentAsString();
reader.ReadToFollowing("Name");
ManufacturerName = reader.ReadElementContentAsString();
reader.ReadToFollowing("Code");
ProdCategoryCode = reader.ReadElementContentAsString();
reader.ReadToFollowing("Code");
BarcodeCode = reader.ReadElementContentAsString();
//Here I use "code", "Name", "ManufacturerName" variables to insert into a database
} while (reader.Read());
reader.Close();
All XML tags are present in all products except the <Barcodes> childs (<Barcode><Code>) that is present only on some product, then I cannot jump at next "code" with last ReadToFollowing because if not present I capture the first <product><code>.
I cant control XML output and cant modify it (is third-party).
There's a way to "ReadToFollowing('<Barcodes><Barcode><Code>')" so that I can specific what should seek and if there is not found I can jump it?
Thank you for your help, excuse my bad english.
I would suggest to pull each Product element into a tree model, using either https://msdn.microsoft.com/en-us/library/system.xml.linq.xnode.readfrom(v=vs.110).aspx or https://msdn.microsoft.com/en-us/library/system.xml.xmldocument.readnode(v=vs.110).aspx, then you can use LINQ to XML query methods or XPath to read out the data of each Product in a safe way while maintaining a low memory footprint.

DataSet.WriteXml() - how to "drop" some fields

I've 2 questions:
First, I've a dataset with 5 tables. I've made the relationships of tables and generating an XML from this dataset like this:
StreamWriter xmlDoc = new StreamWriter("myxml.xml", false);
ds.WriteXml(xmlDoc);
xmlDoc.Close();
Some of the fields in each table in dataset are primary keys and I dont want to show them in XML. If I exclude them from tables, I cant make relationships. Can anybody give me some idea that how to write dataset to XML "droping" the key fields (columns in datatables)? For example, here is the XML generating at the moment:
<?xml version="1.0"?>
<o>
<sp spname="SP1" spid="8">
<event spid="8" eventname="Event1" eventId="482">
<bm bmname="BM1" bmid="2" bmeid="826" eventid="482">
<att bmeid="826" val="3.00" attname="Att1" atttype="Type1" attid="23172"/>
<att bmeid="826" val="3.50" attname="Att2" bettype="Type1" attid="23173"/>
</bm>
</event>
</sp>
</o>
but I want this XML to be generated like this (all id attributes should be "dropped" as all ids are for relationships and should not be added in XML):
<?xml version="1.0"?>
<o>
<sp spname="SP1">
<event eventname="Event1">
<bm bmname="BM1" bmid="2">
<att val="3.00" attname="Att1" atttype="Type1" />
<att val="3.50" attname="Att2" bettype="Type1" />
</bm>
</event>
</sp>
</o>
And now 2nd question:
I've given name to my dataset as "o" so its generating the xml as you can see above. I want to add some attributes to <o> node like current datetime. I mean I want <o> node to be genrated as <o generatedDate="09/13/2011" generatedTime="03:45 PM">. How can I achieve it?
Thanks,
You can hide the column to exclude it from the XML-File:
dataSet.Tables["TableName"].Columns["ColumnName"].ColumnMapping = MappingType.Hidden;
One option is to use LINQ to XML to alter the document. Another option would be to pass the XML into an XSLT transformer, which can parse the XML and output the desired results.
Transforming a DataSet using XSLT:
DataTable table = new DataTable();
System.IO.StringWriter writer = new System.IO.StringWriter();
//notice that we're ignoring the schema so we get clean XML back
//you can change the write mode as needed to get your result
table.WriteXml(writer, XmlWriteMode.IgnoreSchema, false);
string dataTableXml = writer.ToString();
As for displaying it in a readable format, I would suggest passing the XML into an XSL transformer, which you can then use to parse the XML and manipulate the output as needed.
Applying an XSLT Transform to a DataSet
http://msdn.microsoft.com/en-us/library/8fd7xytc%28v=vs.71%29.aspx#Y289
Here's a simple example I created to explain how you would use the XSL transformer. I haven't tested it, but it should be pretty close:
DataSet ds = new DataSet();
StringBuilder sbXslOutput = new StringBuilder();
using (XmlWriter xslWriter = XmlWriter.Create(sbXslOutput))
{
XslCompiledTransform transformer = new XslCompiledTransform();
transformer.Load("transformer.xsl");
XsltArgumentList args = new XsltArgumentList();
transformer.Transform(new XmlDataDocument(ds), args, xslWriter);
}
string dataSetHtml = sbXslOutput.ToString();
Formatting XML as HTML using XSLT
Here's an example of using XSLT to transform XML into an HTML table. It should be fairly easy to adopt so you can use it with your serialized DataSet.
Let's say this is your DataSet, serialized to XML:
<RecentMatter>
<UserLogin>PSLTP6\RJK</UserLogin>
<MatterNumber>99999-2302</MatterNumber>
<ClientName>Test Matters</ClientName>
<MatterName>DP Test Matter</MatterName>
<ClientCode>99999</ClientCode>
<OfficeCode/>
<OfficeName/>
<Billable>true</Billable>
<ReferenceId/>
<LastUsed>2011-08-23T23:40:24.13+01:00</LastUsed>
</RecentMatter>
<RecentMatter>
<UserLogin>PSLTP6\RJK</UserLogin>
<MatterNumber>999991.0002</MatterNumber>
<ClientName>Lathe 1</ClientName>
<MatterName>LW Test 2</MatterName>
<ClientCode/>
<OfficeCode/>
<OfficeName/>
<Billable>true</Billable>
<ReferenceId/>
<LastUsed>2011-07-12T16:57:27.173+01:00</LastUsed>
</RecentMatter>
<RecentMatter>
<UserLogin>PSLTP6\RJK</UserLogin>
<MatterNumber>999991-0001</MatterNumber>
<ClientName>Lathe 1</ClientName>
<MatterName>LW Test 1</MatterName>
<ClientCode/>
<OfficeCode/>
<OfficeName/>
<Billable>false</Billable>
<ReferenceId/>
<LastUsed>2011-07-12T01:59:06.887+01:00</LastUsed>
</RecentMatter>
</NewDataSet>
Here's an XSLT script that transforms the DataSet to HTML:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<table border="1">
<tr>
<th>User Login</th>
<th>Matter Number</th>
...
</tr>
<xsl:for-each select="NewDataSet/RecentMatter">
<tr>
<td>
<xsl:value-of select="UserLogin"/>
</td>
<td>
<xsl:value-of select="MatterNumber"/>
</td>
...
</tr>
</xsl:for-each>
</table>
</xsl:template>
</xsl:stylesheet>
I would suggest after generating the XML, use LINQ to XML to filter out / add attribute to desired nodes. This filtering and adding attribute is a separate step then generating the XML from data set and should be handled after the XML is generated from data set as that would lead to better design.
