My XML knowledge is extreemly limited but learning not quite fast enough!

I am getting some XML back from the USPS web service as a string

<?xml version="1.0"?>
<ZipCodeLookupResponse><Address ID="0"><Address2>6406 IVY
LN</Address2><City>GREENBELT</City><State>MD</State><Zip5>20770</Zip5><Zip4>1440</Zip4></Address></ZipCodeLookupResponse>

I create a System.Xml.XmlDocument and then load the string.

How do I access the value of "Address ID=" from within C# code using the
XMLDocument?

From one of my books I think this is an attribute but when I check it tells
me there are no attributes in the document.

Thanks
Tom Groszko

Try:

doc.SelectSingleNode("//ZipCodeLookupResponse/Address/@ID").Value

It's in VB, but you can do the same thing in C#.

This may help you too in the future.

I feel your pain. I am working on a C# Web service that is to make contact
with a 3rd party Web service to send/receive XML Documents.

I am learning more about XML than I ever cared to know. :)

I think I got the answer. The Address ID is an attribute of a node not the
document which I was originally checking.

Actually, the attribute is not "Address ID", it is only "ID"
associated with the node "Address". you can check the values like :
xmlDocument.SelectSingleNode("//ZipCodeLookupResponse/
Address").Attributes["ID"].Value. and this will give you the value of
that attribute.

Prajem pekný deň.
Potreboval by som vygenerovať funkciou Random
číslo do nejakej premennej. V praxi by som chcel
vytvoriť nejaký príklad pre výpočet.
Nech som hľadal ako hľadal, ale nič som rozumné nenašiel.
Nemáte nejaký slušný Netlink, kde by to bolo možné doštudovať?
Dik za pomoc.
S pozdravom Miloš
