Re: Question about keys and cross-referencing (was pre

So I've got an input structure like this:

<e eid="e0001"><hg><hw>keyword</hw></hg><se1>...</se1></e>
...
<e eid="e1234"><hg><hw>different_keyword</hw></hg><se1>... <xg>See also <xr>keyword</xr></xg>...</se1></e>

where the <xr> element "keyword" needs to link to the <e> element where the <hw> is "keyword".

I'm thinking that I can set up a key like

<xsl:key name="headwords" match="hw" use="ancestor::e/@eid" />

and then reference it in my xr template like

<xsl:attribute name="href"><xsl:text>#</xsl:text><xsl:apply-templates select="key('headwords',ancestor::e/@eid)" /></xsl:attribute>

Does that sound right?

Sometimes I've got several headwords that are identical except for the homograph numbers, like so:

<e eid="e0003"><hg><hw>keyword</hw><hom>1</hom></hg><se1>...</se1></e>
<e eid="e0004"><hg><hw>keyword</hw><hom>2</hom></hg><se1>...</se1></e>
<e eid="e0005"><hg><hw>keyword</hw><hom>3</hom></hg><se1>...</se1></e>

and these are referenced like so:

<e eid="e2345"><hg><hw>different_keyword</hw></hg>... <xg>See also <xr>keyword</xr><hom>1</hom></xg>...</e>

Is there a way to include those homograph numbers in the key and in the cross-reference so that I get the
correct (I hope unique) link?

Cheers,
Wendell
