Re: [xsl] How do i check null values in a for each???

["Vasu Chakkera" <vasucv@xxxxxxxxxxx>]

Hi suman assuming that ur XML looks like ..

<attributes>
<attr name = "addrdesc">
<value>value1</value>
</attr>
<attr name = "AddrDesc">
<value>value2</value>
</attr>
</attributes>

your xsl would be ..

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">
<xsl:for-each select="/attributes/attr">
   <td>&#160; <input type="text">
    <xsl:attribute name="name">txtAddressDesc</xsl:attribute>
    <xsl:attribute name="value"><xsl:value-of 
select="value[(parent::attr/@name='addrdesc1') or (parent::attr/@name = 
'AddrDesc1')]"></xsl:value-of></xsl:attribute>
    </input>
        </td>
</xsl:for-each>

</xsl:template>
</xsl:stylesheet>

This works FOR THE XML STRUCTURE I HAVE ASSUMED.
---- XSL Gurus .. please advise if there are better ways to do this. ---
