问题
What package shall I use for XPath? I want wo query for elements and then extract some values around these nodes. Maybe one or more levels higher, some attributes.
javax.xml.xpath is XPath 1.0. Is javax.xml.xpath and org.w3c.dom the right way to go, or are there more modern implementations? org.w3c.dom is very awkward, JDOM seems alot easier.
回答1:
You may consider a Java-based XPath 2.0 or XQuery implementation (the XSLT 2.0 choice provides much more powerful functionality), such as Saxon 9.x.
Saxon is open source and one of the highest quality java-based processor so far and I am using it on a daily basis when answering SO XSLT/XPath/XQuery questions. In the documentation you will find good code examples.
The only stand-alone XPath 2.0 implementation I am aware of is PsychoPath, but I am not sure of its quality and usability.
