What is wrong with the xml code - asp.net

I got this question in an exam to specify what is wrong with this piece of XML code and I have no idea what the answer might be:
<contact id=”10” name=”randomName” email=”first.last#gmail.com” phone=”09090909”/>
I am guessing that the email would be prone to spam or something.

Original answer: you cannot name an attribute "id" in XML for your own purpose. It is a reserved name of the XML schema space which actually serves to identify a specific element to then do a look up by XML id.
EDIT
The issue with the XML might be a modeling one. The fact you use attributes for name, email, and phone means that a contact can only ever have one value of each. Maybe your professor is after a new model e.g.:
<contact id="10" name="foo">
<email>sdfsdfsdf</email>
<email>sdfsdfsdf</email>
</contact>

XML attributes are not intended to carry the object data.
Your XML should be structured like this:
<contact>
<id>10</id>
<name>randomName</name>
<email>first.last#gmail.com</email>
<phone>09090909</phone>
</contact>

How to select the right <category> in RSS? is there a list?

i am noting that in a RSS feed you can add the tag
Source: https://www.w3schools.com/xml/rss_tag_category_item.asp
But I don't undestand one thing: is there a list with all the categories? Or can I write anything? I need a category about videogames
Or can I write anything?
You can write anything.
Unless you're submitting your feed to a directory, with a documented set of categories, it's essentially free text.
However, in RSS:
It has one optional attribute, domain, a string that identifies a categorization taxonomy.
The value of the element is a forward-slash-separated string that identifies a hierarchic location in the indicated taxonomy.
and in Atom:
The "scheme" attribute is an IRI that identifies a categorization
scheme.
you can indicate that your term is from a specific scheme.
In practice, some schema extensions like iTunes introduce a separate element:
<rss version="2.0" xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd"
...
<itunes:category text="Sports">
<itunes:category text="Wilderness"/>
</itunes:category>
rather than suggesting use of the scheme attribute. The iTunes guide currently includes:
<itunes:category text="Leisure">
<itunes:category text="Video Games" />
</itunes:category>

Missing Root node in xml file in biztalk

I have researched a lot on internet, but still not able to get exact solution for my problem. The problem mentioned in below link is much similar to mine, but this will not work.
If record exists then map, if not map another - Biztalk mapping
My Problem:
I have xml source file which has invoice information, something like this.
-<invoice>
<invoiceNumber>1124</invoiceNumber>
+<invoiceHeader>
+<invoiceDetails>
</invoice>
<invoiceNumber>1598</invoiceNumber>
+<invoiceHeader>
+<invoiceDetails>
</invoice>
It is possible that, sometimes the subnode ie. invoiceDetails information can be missing for few invoice Numbers,but header information will be present.
Output required:
The output file (.csv) should have all invoice numbers irrespective of detail tag present or not?
Add a Looping Functoid to the Map with the source link from and the target from the Looping Functoid linked to the row element in the Flat File Schema.
It will work, trust us. :)
It depends on how is the output schema, but solution must be easy only link tag to the output.
Behind the scenes, the XSLT produced is a loop for each tag and copy that value to the output, irrespective of detail tag present or not.

OSB reporting, report multiple content. $body, $inbound, $outbound

I am trying to put multiple values inside this content with this XQuery Expression Builder. I tried to use a string function like thisfn:concat($body, $inbound, $inbound), but this does not seems to keep the whole message.
Is there any way that I can put all these variables in one report action? If this is possble then how should I read these values out after they are stored in the database(some key value structure would be perfect).
You only need to form a xml with the content you want to show in your report:
<report>
<body>{$body}</body>
<inbound>{$inbound}</inbound>
...
</report>
the only requirement is that the output have to be an XML no matter the structure.
Not sure, but I would try something like this:
<myroot>{$body, $inbound, $outbound}</myroot>
Or if you really need a string returned:
fn:serialize(<myroot>{$body, $inbound, $outbound}</myroot>)
Note, fn:serialize is only in OSB 12c+.

XQuery - remove nodes based on its sub element being in the "ban" list

I am a total noob with XQuery, but before at start digging deep into it, i'd like to ask some experts advice about whether i am looking at the correct direction.
The problem:
A huge xml file which contains a whole lot of users and their access information (password access rights and so on) example below:
<user>
<name>JC1234</name>
<password>popstar</password>
<accesslevel>0</accesslevel>
</user>
<user>
<name>AHkl</name>
<password>Rudy10!</password>
<accesslevel>2</accesslevel>
</user>
i have a list of user names (csv file) that i need to remove from that huge xml files.
the result should be a new xml file wihtout those removed users....
is this feasable with XQuery?
any advice for a quick and dirty solution is welcomed!
There is no standard way of loading a CSV file in vanilla XQuery 1.0, although most implementations have an unparsed-text function or similar. If not the contents of the file can be passed in as a parameter.
The CSV file can be parsed using the tokenize function:
declare variable $names = tokenize(unparsed-text("banned.csv"), ",")
And the actual query is quite straightforward. Assuming your document is a a fragment containing just a list of <user /> nodes then the query is simply
doc("users.xml")/user[not(name=$names)]
If however the XML file contains a lot of other data then you may find XSLT's templating facilities more useful.

How to extract element id attribute values from HTML

I am trying to work out the overhead of the ASP.NET auto-naming of server controls. I have a page which contains 7,000 lines of HTML rendered from hundreds of nested ASP.NET controls, many of which have id / name attributes that are hundreds of characters in length.
What I would ideally like is something that would extract every HTML attribute value that begins with "ctl00" into a list. The regex Find function in Notepad++ would be perfect, if only I knew what the regex should be?
As an example, if the HTML is:
<input name="ctl00$Header$Search$Keywords" type="text" maxlength="50" class="search" />
I would like the output to be something like:
name="ctl00$Header$Search$Keywords"
A more advanced search might include the element name as well (e.g. control type):
input|name="ctl00$Header$Search$Keywords"
In order to cope with both Id and Name attributes I will simply rerun the search looking for Id instead of Name (i.e. I don't need something that will search for both at the same time).
The final output will be an excel report that lists the number of server controls on the page, and the length of the name of each, possibly sorted by control type.
Quick and dirty:
Search for
\w+\s*=\s*"ctl00[^"]*"
This will match any text that looks like an attribute, e.g. name="ctl00test" or attr = "ctl00longer text". It will not check whether this really occurs within an HTML tag - that's a little more difficult to do and perhaps unnecessary? It will also not check for escaped quotes within the tag's name. As usual with regexes, the complexity required depends on what exactly you want to match and what your input looks like...
"7000"? "Hundreds"? Dear god.
Since you're just looking at source in a text editor, try this... /(id|name)="ct[^"]*"/
Answering my own question, the easiest way to do this is to use BeautifulSoup, the 'dirty HTML' Python parser whose tagline is:
"You didn't write that awful page. You're just trying to get some data out of it. Right now, you don't really care what HTML is supposed to look like. Neither does this parser."
It works, and it's available from here - http://crummy.com/software/BeautifulSoup
I suggest xpath, as in this question
