Subject: Re: [xsl] Keys off of variable xml source From: Wendell Piez <wapiez@xxxxxxxxxxxxxxxx> Date: Fri, 01 Apr 2005 12:08:39 -0500 |
The reason for a lookup xml source is to act as a cross-reference to data in the main xml source. So, I need to reference all elements who's ID = 123 but my match is expressed as a code value "abc". The code "abc" maps to 123 in my lookup. So, I'm still scratching my head wondering how I might effectively put the external file to use with keys, but thinking it won't work, the context would strictly be of the main xml source.
source: <match code="abc"/>
lookup: <code lookup="abc" value="123"/>
<xsl:template match="match"> <xsl:variable name="lookup-code" select="@code"/> <xsl:variable name="target-id"> <xsl:for-each select="$lookup"/> <xsl:value-of select="key('codes',$lookup-code)/@value"/> </xsl:for-each> </xsl:variable> ... now the value '123' is available bound to $target-id (as an RTF, convertible to a string) ... </xsl:template>
Cheers, Wendell
