Hi all, i'm a librarian with a problem: i've to change the value of attribute
for each element of a group that i'm not able to select and count.
i've something like this:
<mets:div LABEL="Testo" ORDER="4" ORDERLABEL="1">
<mets:div LABEL="Frontespizio" ORDER="1" ORDERLABEL="1">
<mets:div LABEL="Pagina 5" ORDER="1" ORDERLABEL="5">
<mets:fptr FILEID="file.00008"/>
</mets:div>
</mets:div>
<mets:div LABEL="Dedica" ORDER="2" ORDERLABEL="1">
<mets:div LABEL="Pagina 6" ORDER="1" ORDERLABEL="6">
<mets:fptr FILEID="file.00009"/>
</mets:div>
</mets:div>
<mets:div LABEL="Canto I" ORDER="3" ORDERLABEL="1">
<mets:div LABEL="Pagina 7" ORDER="1" ORDERLABEL="7">
<mets:fptr FILEID="file.00010"/>
</mets:div>
<mets:div LABEL="Pagina 8" ORDER="2" ORDERLABEL="8">
<mets:fptr FILEID="file.00011"/>
</mets:div>
<mets:div LABEL="Pagina 9" ORDER="3" ORDERLABEL="9">
<mets:fptr FILEID="file.00012"/>
</mets:div>
</mets:div>
</mets:div>
i have to change the value of LABEL from "pagina 5, pagina 6, pagina 7, pagina 8, etc..."
to "carta 1r, carta 1v, carta 2r, carta 2v, etc".
So the problem is that i've a order of pages with a kind of enumeration, and it
will became a list of a double enumeration. each number is repeated.
It will be something like this:
<mets:div LABEL="Testo" ORDER="4" ORDERLABEL="1">
<mets:div LABEL="Frontespizio" ORDER="1" ORDERLABEL="1">
<mets:div LABEL="Carta 1r" ORDER="1" ORDERLABEL="5">
<mets:fptr FILEID="file.00008"/>
</mets:div>
</mets:div>
<mets:div LABEL="Dedica" ORDER="2" ORDERLABEL="1">
<mets:div LABEL="Carta 1v" ORDER="1" ORDERLABEL="6">
<mets:fptr FILEID="file.00009"/>
</mets:div>
</mets:div>
<mets:div LABEL="Canto I" ORDER="3" ORDERLABEL="1">
<mets:div LABEL="Carta 2r" ORDER="1" ORDERLABEL="7">
<mets:fptr FILEID="file.00010"/>
</mets:div>
<mets:div LABEL="Carta 2v" ORDER="2" ORDERLABEL="8">
<mets:fptr FILEID="file.00011"/>
</mets:div>
<mets:div LABEL="Carta 3r" ORDER="3" ORDERLABEL="9">
<mets:fptr FILEID="file.00012"/>
</mets:div>
</mets:div>
</mets:div>
The following stylesheet produces above output (minus indentation):
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:mets="http://www.loc.gov/METS/";
version="2.0">
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@*, node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="mets:div/@LABEL[matches(., '^Pagina [0-9]+$')]">
<xsl:variable name="n">
<xsl:number level="any" count="mets:div[(_at_)LABEL[matches(.,
'^Pagina [0-9]+$')]]"/>
</xsl:variable>
<xsl:attribute name="LABEL" select="concat('Carta ', if ($n mod 2 =
0) then concat(($n + 1) idiv 2, 'v') else concat(($n + 1) idiv 2, 'r'))"/>
</xsl:template>
</xsl:stylesheet>
