I wonder if anybody could quickly profer some advice on this.
I may well be wrong, but does xsl treat attribute strings different to
normal text nodes when it comes to the "contains()" function. I may well
also be gibbering. I've got my mind into a muddle on this one.
Problem : To take an attribute in the form of a comma delineated string
(e.g. <gui onShow="apple,pear,banana" onHide="black,white,grey"/>) and
to covert the attributes into javascript array syntax (i.e.
['apple','pear','banana'] etc.).
Strategy : "Just" replace the commas with ',' and top and tail the
output string with [' and ']
Code :
<!--To convert onShow-->
<xsl:call-template name="commaDelineate"><xsl:with-param name="str"
select="@onShow"/></xsl:call-template>
<xsl:template name="commaDelineate">
<xsl:param name="str"/>
<xsl:when test="contains($str,',')">
<xsl:value-of select="substring-before($str,',')"/>','
<xsl:call-template name="commaDelineate">
<xsl:with-param name="str" select="substring-after($str,',')"/>
</xsl:call-template>
</xsl:when>
</xsl:template>
Frustration : The errors seem to be generated around the "when"
statement. Unfortunately I can't provide any error output because this
is being done inside a PHP script.
Many thanks for reading this... if anyone has any advice about +why+
this isn't working, and where I ought to go, I'd be grateful. Thanks.
Ben
