Is there any way to get information from the context of the current XPath expression, and use that inside a predicate expression. For example, if I have <doc> <state id="OH">Ohio</state> <state id="PA">Pennsylvania</state> <home state="PA"/> <home state="OH"/> </doc> I want to write an XPath expression that will give me the name of the state assigned to the home element. Something like this works as long as long as there is only one home: /doc/state[@id=/doc/home/@state] But what I want to do is evaluate an XPath at any home node and get the state name for that node. Something like: /doc/state[@id=current()/@state] Where current would be the context node when the XPath evaluation starts. The problem is that current() is not a part of XPath... In XSLT I would do this using a variable. <xsl:variable name="state"> <xsl:value-of select="@state"/> </xsl:variable> <xsl:value-of select="/doc/state[@id=$state]"/> But, it seems like there should be a way to do this with XPath alone. Is there a way? Thanks, Harold Putman
