RE: Xpath expression with " | "

2004-08-05 03:11:08
i found on an old xsl an "Xpath" expression like this:


<xsl:if test=" /AAA /BBB/( CCC | EEE ) [ . != '']">

This is legal in XPath 2.0 but not in XPath 1.0.

It might also have been legal in Microsoft's WD-xsl dialect, I have no idea.

In XPath 1.0 it needs to be expanded to 

 (/AAA/BBB/CCC | /AAA/BBB/EEE ) [ . != '']

      <xsl:apply-template.........

i test it with xalan/Tomcat (last version) and have the error for this
line:

A stage of site was awaited after the token ''/'' or ''//''

the expression   /BBB/( CCC | EEE )  is not valid ?
Is there an alternativ grammar for multi union  ?

merci
