Hi, I have a problem I couldn't find the way to solve. Sadly if it's not possible. That's the code from XSLT extensions tutorial: <xsl:template match="*"> <my:python-extension> <some-content /> </my:python-extension> </xsl:template> Everything's working cool, but I need a bit more: <xsl:template match="*"> <my:python-extension> <something><xsl:attribute name="test"><xsl:value-of select="111" /></xsl:attribute></something> </my:python-extension> </xsl:template> Let's assume that's my execute function's signature: execute(self, context, self_node, input_node, output_parent) When it's started by XSLT processor, self_node contains <something> tag with <xsl:attribute> and <xsl:value-of> tags inside it. What should I do to ask XSLT processor to evaluate it? I need to make self_node containing <something test="111" />. And even more. What if my XSLT file looks like: <xsl:template match="*"> <my:python-extension> <something> <xsl:attribute name="test"><xsl:value-of select="111" /></xsl:attribute> <my:python-extension> <xsl:attribute name="test2"><xsl:value-of select="222" /></xsl:attribute> </my:python-extension> </something> </my:python-extension> </xsl:template> I need to have execute function called for deepest <my:python-extension> first, I need to evaluate <xsl:attribute> inside it to have <my:python-extension test2="222">... And to process the rest <my:python-extension> having the result of processed <my:python-extension test2="222"> and all XSLT instructions inside. Is there a way to do it? Or maybe there is some other way to get such possibilities? Thanks. -- Marat
