Hi All, I posted this originally to an xml group and got no response.
Hoping someone here has some insight.
New to asp.net here. Been combing google since monday trying to
find the right solution. Most of the solutions are good and reflect the
same examples in the .net books I have but xml is sketchy to me and
this isn't you typical real world project.
Here's the scenario. I query an api via a URL and it responds with xml
data which I need to use to prepoulate the fields of a web form. I
haven't been able to get my head around this one. As you can see from
the XML example below, all of the elements I am after (name, address,
phone etc) have the same element name "attr". I have no control over
the xml document so I can't arrange the tags in a more useful manner.
If you look at the xml, I need to assign each value to a corresponding
textfield on a web form. So the value of attr name="mail" which is
j...@msn.com must be assign to txtMail.text. So far I have been able to
return all of the values but I have not been successful in linking them
to that childnode (if thats correct) of name, mail, address etc.
Also should mention I can't really use an array solution like attr[1],
attr[2] which will work, but as I said I have no control over the xml
doc and if the positions change my app is hosed.
My deadline is tomorrow so thank you sincerely for any and ALL
suggestions.

You have to select the attribute:
The xpath string should be something like this (I haven't checked it: use it
just for reference)
"//entry/attr[@name='mail']"
That means: select the 'attr' nodes that have an attribute named name with
the value of 'mail'.
Here you will find some examples: http://www.w3schools.com/xpath/xpath_syntax.asp
Hope this will help.
Regards.

Try something like this:
XmlDocument xmlDoc = new XmlDocument();
// ...load XML from your API into xmlDoc
string nodePath =
"/dnt/directory-entries/entry/attr[@name='mail']/value";
txtMail.Text =
xmlDoc.DocumentElement.SelectSingleNode(nodePath). InnerText;

It sounds like your problem is an XPath one. To get the value of the city, for example, you would use an XPath such as:
"/dnt/directory-entries/entry/attr[@name='city']/value"

Thank you all.
Chris your solution turned out to be the fix - bless you!
I played with xPath for 3 days and couldn't get it to give me
everything required. I figure either it is because of the structure of
the xml file or just my being a .net newb. Probably the latter of the
two (I miss classic asp).
I soon as I meet my deadline I'll post my solution.
