I'm a toal newbie with XPath, so please bear with me. I have read through the tutorials and still c +an't figure out how to do what I need. I have an XML file whose structure looks like this: <question> <term> <validity> <decision&gt;yes&lt;/decision> </validity> </term> </question> where the decision could be either yes or no. The file has lots of other tags, but those will suffi +ce for this post. I want to select all the <question> nodes whose decision is 'yes'. I am able to retrieve all the <decision> nodes whose value is yes with this expression: //question/terme/validite[decision='oui'] but I can't figure out how to retrieve the <question> nodes which are ancestors of those. Thank you for your help.
