Question

I have XSLT 1.0 code like this:

<xsl:key name="enemyItems"
         match="metadata[attributes/metadata_key/@value = 'enemylist']"
         use="attributes/metadata_refkey/@value"/>

<xsl:template match="item">
    <xsl:variable name="enemyList"
                  select="key('enemyItems', @key)/attributes/@value"/>
    <xsl:if test="string-length($enemyList) > 0">
        <xsl:value-of select="@name"/>
    </xsl:if>
</xsl:template>

As I understand it, a key can store more than one value for a particular element. I believe the code above is only getting the first value when referring to key('enemyItems', @key).

So, I want to wrap that code in an xsl:for-each, like this

    <xsl:template match="item">
        <xsl:for-each select="key('enemyItems', @key)">
            <xsl:variable name="enemyList"
                      select="???/attributes/@value"/>
            <xsl:if test="string-length($enemyList) > 0">
                <xsl:value-of select="@name"/>
            </xsl:if>
        </xsl:for-each>
    </xsl:template>

My question is: What goes in the ??? part? (That is, what is the name of the iteration variable or thing?)

Answer 1

Inside an xsl:for-each tag, the context on each iteration is the node being examined. Thus the ??? in your question should be replaced with .
