Subject: [xsl] Functions Returning Nodes in XSLT 2.0 From: Alan Gutierrez <alan-xsl-list@xxxxxxxxx> Date: Thu, 19 May 2005 19:33:48 -0400 |
In XSLT 2.0 with Saxon 8.4... I've written helper methods that look like so. <xsl:function name="fn:user" as="element()"> <xsl:param name="login"/> <xsl:copy-of select="document('users.xml')/users/user[login = $login]"/> </xsl:function> Making it easier to write select attributes. <xsl:value-of select="fn:user()/first-name"/> Some of my XPath is getting complicated, so I like to wrap it up into functions. I'm wondering if copy-of is smart enough to forgo copying in such cases. If not, I could see how it could get expensive to call fn:user every time I wanted a property. Is there a better practice for this sort of thing? -- Alan Gutierrez - alan@xxxxxxxxx - http://engrm.com/blogometer/index.html - http://engrm.com/blogometer/rss.2.0.xml
