I doubt that'll work. Imagine someone authoring a document; they add a citation, and want to run the output transformation again.

Can the former be made faster?

The easiest way is instead of sending a single query for each distinct-value of the "citekey" key, I somehow send a query that asks for all of them at once.

I'm not quite sure who to do that, though. I know that I want a "for $key in $keys return mods:mods[ID='$key']" sort of expression; I just don't know how to do that with the key.

<xsl:template match="db:bibliography" mode="create-bibcollection">
<bibliography>
<modsCollection xmlns="http://www.loc.gov/mods/v3">
<xsl:for-each select="distinct-values(key('citekey', 'all'))">
<!--+ ==============================================================

<xsl:variable name="bibrecord" select='doc(concat("http://localhost:8080/exist/servlet/db/biblio?",
"_query=declare%20namespace%20mods=%22http://www.loc.gov/mods/ v3%22;",
"/mods:modsCollection/mods:mods[@ID=&apos;", ., "&apos;]"))'/>
<xsl:copy-of select="$bibrecord/exist:result/mods:mods" />
</xsl:for-each>
</modsCollection>
</bibliography>
</xsl:template>
