Hi Folks,

I have an XSLT program that locates all leaf elements which have the string value 'DNKK'. My program outputs the element and the name of its parent:

     <xsl:template match="/">
         <results>
             <xsl:for-each select="//*[not(*)][. eq 'DNKK']">
                 <result>
                     <xsl:sequence select="."/>
                     <parent><xsl:value-of select="name(..)"/></parent>
                 </result>
             </xsl:for-each>
         </results>
     </xsl:template>

The input XML document is large, nearly 5GB.

When I run my program SAXON throws the OutOfMemoryError message shown below.

To solve the OutOfMemoryError I could add to my heap space (-Xmx) when I invoke Java. But I wonder if there a way to write my program so that it is more efficient (i.e., doesn't require so much memory)?
