[xsl] how to call extension function for side-effect, portably?
Subject: [xsl] how to call extension function for side-effect, portably? From: Kevin Rodgers <kevin.rodgers@xxxxxxx> Date: Tue, 18 Jan 2005 13:46:18 -0700 |
What is the appropriate XSL instruction to call an extension for side-effect only? Currently I've got this in my stylesheet: <xsl:variable name="foo" select="document('file:///tmp/foo.xml')"/> <xsl:if test="function-available('saxon:discard-document')" xmlns:saxon="http://saxon.sf.net/"> <xsl:variable name="dummy" select="saxon:discard-document($foo)" xmlns:saxon="http://saxon.sf.net/"/> </xsl:if> Which not surprisingly generates a warning (from Saxon): Warning: at xsl:variable on line 11 of file:/tmp/foo.xsl: A variable with no following sibling instructions has no effect -- Kevin Rodgers
