Re: [xsl] Passing arrays into XSL

[Deepak <deepak_vn@xxxxxxxxx>]

Hi Jern,

Thanks for your help.

But my need is bit different, we have to match with
the strings from the variable or the parameter from a
servlet response. 

  So i need to match those strings available in the
'param' with actual xml file. The xml file nodes may
be more than blue,red colors.  So the XSL display
should be depends on the values available in the
param. The parameter string may be with a delimiter
','(red, blue) or '' (red blue). 

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:param name="arrayString">
   blue,red
</xsl:param>

<xsl:template match="colors">

<xsl:if test="contains(color,$arrayString)">
 <xsl:text> do something</xsl:text>
</xsl:if>
</xsl:template>

</xsl:stylesheet>

Please let me is the'r anything left behind.

Thanks,
Deepak
