This is a question related to getting Drupal CCK fields (just in case that happens to change anything).
I have several Drupal CCK fields with similar names. They have the same name with a number at the end. that I'd like to pull values from these fields (ten fields total). This is the syntax for accessing the fields values:
$node->cck_field_1[0]['value']
$node->cck_field_2[0]['value']
$node->cck_field_3[0]['value']
…etc.
Since they're all separate fields, but they're numbered, I'd like to just loop through incrementally to write out what I need (there's a lot more to what I'm writing than just accessing these fields' data, but they're the determining factors of the rest), but I can't figure out how to insert a variable into that part of the code.
e.g., (if $i were the incremental number variable), I'd like to be able to write the following string as a variable:
'$node->cck_field_' . $i . '[0]["value"]'
I understand about using the curly brackets to create a variable name from a string, but the part I need the variable in needs to be outside of the string. e.g. this works:
${node}->cck_field_1[0]['value']
but this doesn't:
${node->cck_field_1}[0]['value']
(so I can't write ${'node->cck_field'.$i}[0]['value'] )
So how can write this so that I can use $i in place of the number?
This should work:
$node->{'cck_field_' . $i}[0]['value']

xquery version "1.0-ml";
declare function local:sortit(){
for $i in ('a','e','f','b','d','c')
order by $i
return
element Result{
element N{1},
element File{$i}
}
};
local:sortit()
the above code is sample, I need the data in this format. This sorting function is used multiple places, and I need only element N data some places and only File element data at other places.
But the moment I use the local:sortit()//File. It removes the sorting order and gives the random output. Please let me know what is the best way to do this or how to handle it.
All these data in File element is calculated and comes from multiple files, after doing all the joins and calculation, it will be formed as XML with many elements in it. So sorting using index and all is not possible here. Only order by clause can be used.
XPath expressions are always returned in document order.
You lose the sorting when you apply an XPath to the sequence returned from that function call.
If you want to select only the File in sorted order, try using the simple mapping operator !, and then plucking the F element from the item as you are mapping each item in the sequence:
local:sortit() ! File
Or, if you like typing, you can use a FLWOR to iterate over the sequence and return the File:
for $result in local:sortit()
return $result/File
Hi Progress OpenEdge dev,
I am using the following syntax to generate an XML file from temp table. All is good but for one item.
dataset dsCust:write-xml("FILE", "c:/Test/Customer.xml", true).
This is my temp table declaration
def temp-table ttCustomer no-undo
namespace-uri "http://WMS.URI"
namespace-prefix "ns0"
field PurchaseOrderNumber as char
field Plant as char.
This is my output
<ns0:GoodsReceipt xmlns:ns0="http://WMS.URI">
<ns0:PurchaseOrderNumber/>
<ns0:Plant>Rose</ns0:Plant>
</ns0:GoodsReceipt>
But this is my desired output
<ns0:GoodsReceipt xmlns:ns0="http://WMS.URI">
<PurchaseOrderNumber/>
<Plant>Rose</Plant>
</ns0:GoodsReceipt>
Notice the element inside GoodsReceipt node does not have ns0 prefix.
Can this achived using write-xml? I want to avoid using DOM or SAX if possible.
Thank you
You can always manually set attributes and tag-names using XML-NODE-TYPE and SERIALIZE-NAME.
However: I've worked with lot's of xml:s and API:s together with Progress OpenEdge and have yet to fail based on namespace-problems but I guess it might depend on what you want to do with the data.
Since you don't include the entire dataset this is something of a guess. It produces more or less what you want for this specific case. I don't know how multiple "receipts" should be rendered though so you might need to change this.
DEFINE TEMP-TABLE ttCustomer NO-UNDO SERIALIZE-NAME "ns0:GoodsReceipt"
FIELD xmlns AS CHARACTER SERIALIZE-NAME "xmlns:ns0" INITIAL "http://WMS.URI" XML-NODE-TYPE "ATTRIBUTE"
FIELD PurchaseOrderNumber AS CHARACTER
FIELD Plant AS CHARACTER .
DEFINE DATASET dsCust SERIALIZE-HIDDEN
FOR ttCustomer .
CREATE ttCustomer.
ASSIGN Plant = "Rose".
DATASET dsCust:write-xml("FILE", "c:/temp/Customer.xml", TRUE).
From a quick Google on the subject, it seems the W3C suggests that the namespace prefix should be presented the way OpenEdge does it: https://www.w3schools.com/xml/xml_namespaces.asp
And I'm pretty certain you can't change the behaviour with write-xml like you want to either. The documentation doesn't mention any way of overriding the behaviour. https://documentation.progress.com/output/ua/OpenEdge_latest/index.html#page/dvxml/namespace-uri-and-namespace-prefix.html
I have the data as below manner.
<Status>Active Leave Terminated</Status>
<date>05/06/2014 09/10/2014 01/10/2015</date>
I want to get the data as in the below manner.
<status>Active</Status>
<date>05/06/2014</date>
<status>Leave</Status>
<date>09/10/2014</date>
<status>Terminated</Status>
<date>01/10/2015</date>
please help me on the query, to retrieve the data as specified above.
Well, you have a string and want to split it at the whitestapces. That's what tokenize() is for and \s is a whitespace. To get the corresponding date you can get the current position in the for loop using at. Together it looks something like this (note that I assume that the input data is the current context item):
let $dates := tokenize(date, "\s+")
for $status at $pos in tokenize(Status, "\s+")
return (
<status>{$status}</status>,
<date>{$dates[$pos]}</date>
)
You did not indicate whether your data is on the file system or already loaded into MarkLogic. It's also not clear if this is something you need to do once on a small set of data or on an on-going basis with a lot of data.
If it's on the file system, you can transform it as it is being loaded. For instance, MarkLogic Content Pump can apply a transformation during load.
If you have already loaded the content and you want to transform it in place, you can use Corb2.
If you have a small amount of data, then you can just loop across it using Query Console.
Regardless of how you apply the transformation code, dirkk's answer shows how you need to change it. If you are updating content already in your database, you'll xdmp:node-delete() the original Status and date elements and xdmp:node-insert-child() the new ones.
Is it possible to get a list of declared variables with a VimL (aka VimScript) expression? I'd like to get the same set of values that will be presented for a command using -complete=expression. The goal is to augment that list for use in a user-defined command completion function.
You can use g: as a dictionary that holds all global variables, so:
let globals = keys(g:)
will give you all the names. The same applies to the other scopes: b:, s:, w:, etc. See :help internal-variables for the complete list.
You can get something similar using keys of g:, b:, t:, w: and v: dictionaries, but beware of the following facts:
There is no equivalent to this dictionaries if you want to complete options.
Some variables like count (but not g:count or l:count), b:changedtick and, maybe, others are not present in this dictionaries.
Some vim hacker may add key ### to dictionary g:, but it won't make expression g:### valid variable name (but adding 000 there will). Though g:["###"] will be a valid expression.
$selectVolID = "Select COUNT(VolunteerID) from planetVolunteers";
$getVolID = odbc_exec($connect, $selectVolID);
echo odbc_result_all($getVolID);
gives:
Expr1000
49
1
49 is the correct count. I want to change the Expr1000 to something legible and get rid of that 1 (which i assume means there are no more values to count).
You can use an alias in the SELECT statement to a more descriptive name:
SELECT COUNT(VoluneerID) NumVolunteers from ...
Depending on the underlying database engine, it is possible that the AS keyword migh be needed in front of the alias.
I have dealt very little with PHP, so I do not know about the 1 that is printed.
The number at the end should be the total number of rows returned. The best way I know of to remove it would be to put it in a hidden input, which means you can refer to it later with javascript or something if you really needed to, and also lets you hide it easily.. anything wrapped around the odbc_results_all function only effects the returning row count instead of the whole table (so you can use anything, maybe a div will be better).
echo "<input value=\"" . odbc_result_all($getVolID) . "\" type=\"text\" style=\"display:none;\">";
