Thanuja RaoSubject: Accessing an attribute based on the value of another attribute
Author: Thanuja Rao

Hi All,

I have an XML which looks something like this.
<ROOT>
<TAG1>
<SUBTAG ID="0">blah blah</SUBTAG>
</TAG1>
<TAG2 ID="0 blah" SCORE="0">
</TAG2>
</ROOT>

In my XSL, I need to access the SCORE attribute of TAG2 based on the value of TAG2 ID attribute which in turn should be the same as SUBTAG ID attribute.
<xsl:template match="SUBTAG">
<xsl:variable name="subtagid">
<xsl:value-of select="@ID"/>
</xsl:variable>
<xsl:value-of select="../TAG2[@ID='$subtagid']/@SCORE"/>
</xsl:template>

The problem here is that i cannot directly check for TAG2[@ID='$subtagid'], instead i need to check for substring(TAG2[@ID],1,1)='$subtagid'. How can i club these 2 statements into one to get the desired output? Please help at the earliest possible.

Thanks,
Tan

Specifically what you're asking for:

What you may want:
<xsl:value-of select="../TAG2[contains(@ID=$subtagid)]/@SCORE"/>
or
<xsl:value-of select="../TAG2[substring(@ID,1,string-length($subtagid))=$subtagid]/@SCORE"/>


Another possible way to do this without a variable:
<xsl:value-of select="../TAG2[substring(@ID,1,1)=current()/@ID]/@SCORE"/>
