Element person=people.selectNodes("//Person[@id='282']");
Element firstName= person.element("FirstName");
This will select from the people element all Person tags with and id attribute of 282.
I highly recommend using XPE to play with the correct XPath expressions. It will allow you to "click" on the tag in question and tell you what the XPath would be to reach it. The nicely done tool can be found at
http://www.purpletech.com/xpe .
Also, take a look at the XPath local-name() function, that should help you get around the unknown namespace. You can also do indexing on your list like "//Person[1]" or "//Person[22]" etc.
Hope that helps!

Hi, Firstly, how do you do an xpath search on just an element?<People> <Person id="282"> <FirstName>Jenny<FirstName/> <LastName>Ynnej<LastName/> <Age>1009<Age/> <PhoneNumber>777 777 7777</PhoneNumber> </Person> <Person id="289"> ... ... </People> <People/> is the root element of the document. So lets say you have the <Person> element with id = "282" in an Element object, how do you perform an xpath *relatve to just that element*. personElement.selectNodes("/People/Person/FirstName") works fine, but personElement.selectNodes("/Person/FirstName") does not, so each xpath search is *still* performed on the document as a whole, regardless if you perform it on a sub element. So how do you perform a *relative* search? The "//" is not suitable here. Example: perhaps <PhoneNumber/>'s element is 1 -> Infinity and you only want Jenny's phone numbers and not every one in the entire document. And the second question is about namespaces and xpath. How do you do a search when you don't know what the xml namespace will be in the document, only the structure. So it might be <cool:People/>, <addressBook:People/> or whatever. Current xpath requires you to include the namespace in the path, "/cool:People/cool:Person/..." and so on. What would be the best way to do this dynamically? Regards, Joe
