Extracting Node using Xpath

Hi,

I am newbie in XML working with XPath. I am using Xpath to parse a code that looks like this






I am interested in extracting the node td, (or alternatively the node that has a total of 4 text nodes). I tried using //tr//text(), but it returns all (8) text nodes instead of 4.

Is there any way to specify a node by the number of children it has?

Any help is appreciated.

Thanks

Well, sure. Whenever you are trying to select nodes which satisfy a particular condition, you would put that condition into an XPath predicate. And I believe XPath has a count() function: you could look that up.

However both the "td" elements in your example have five descendants which are text. Not four, there's a whitespace text node in both cases. So comparing the number of text descendants wouldn't help in this caswe.
 
I agree. Here's the link: http://aspose.com/file-tools
