Re: exists function in xslt

> why cant i use:

exists() is an XPath 2 function, and xalan implements Xpath 1.

You don't need it though.

> <xsl:if test="exists(/XPATH-QUERY)) = true">

That tests if the string value of the element <true/> is equal to "true"
which you probably don't want. The XPSLT test would be

 <xsl:if test="exists(/XPATH-QUERY)">

which you can equivalently write as

 <xsl:if test="/XPATH-QUERY">

Which would work also in an XSLT1 processor such as xalan.
