Answer 1

The following XPath expression will select all elements that have given attibute/attribute-value pair:

//*[@foo="bar"]

Example:

<root>
 <grand foo="bar">    <!-- selected -->
   <child foo="nobar"/>
 </grand>
 <grand foo="nobar">
   <child foo="bar"/> <!-- selected -->
 </grand>
</root>

Here’s a tutorial for the Java XPath API (jaxp). It has some snippets that show how to use it.
