<xsl:template match="phrase">
<xsl:variable name="phrase" select="@name"/>
<xsl:variable name="list" select="@list"/>
<span class="phrase"><xsl:value-of
select="//lists/list[@name=$list]/option[@id=$phrase]"/></span>
</xsl:template>
You are taking the "value-of" an option element (which flattens it to a
string), but the option element actually has internal structure that needs
to be further processed. So try this instead:
<xsl:template match="phrase">
<xsl:variable name="phrase" select="@name"/>
<xsl:variable name="list" select="@list"/>
<span class="phrase">
<xslapply-templates
select="//lists/list[@name=$list]/option[@id=$phrase]"/>
</span>
</xsl:template>
I haven't tested this, but it should be the only change you need to make.
Except that if your data contains cycles, your code will probably blow up
with a "stack full" error.
