Question

I am converting code from c# to java.

I have the following xml structure:

<Foo>

<Son>

<Id>xxx</Id>

</Son>

... more sons

</Foo>

I need to select nodes according to the Id value(can be more than one.

I have this line in c#:

XmlNodeList res=xmlDoc.SelectNodes("descendant::Son[Id='xxx']");

I tried to convert it to the following:

NodeList res=(NodeList)xPath.evaluate("xpath expr",inputSource,XPathConstants.NODESET);

However, I didn’t manage to write the right XPath expression.

Any help?

Thanks,
Sara

I’m not at my development machine, but having used XPath in the past, this pops into mind:

xPath.evaluate("/Foo/Son[Id='xxx']",...)

Also, it’s helpful in your question to mention what you’ve tried, and how the results differ from your target output.
