Re: How do I determine if a element exists in an xml file?

Hi cj

As for the response XML document, does it have fixed schema or structure
or will the target elements you want to detect/verify always have some
fixed attributes(such as location in the document or have certain attribute
values ...). If so, I think using XPATH query to locate XML element in a
XML document is the reasonable approach. Here are some web articles
introducing using xpath query in .NET xml processing:
