Hi, I've been working with a OAI-PMH complaint tool and I need to
present the XML data harvested from it in a website. I've accomplished
it so far by creating a XSL file, but encountered some difficulties in
the implementation of severals aspects.
Basicly the XML is exported in the structure shown below:
<?xml version="1.0" encoding="UTF-8" ?>
<?xml-stylesheet type="text/xsl" href="gris2.xsl"?>
<OAI-PMH xmlns="http://www.openarchives.org/OAI/2.0/";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.openarchives.org/OAI/2.0/
http://www.openarchives.org/OAI/2.0/OAI-PMH.xsd";>

Each record as a certain type, described in "dc:type", which may vary as
Paper, Journal, Article, etc;
When harvesting data from the repository, I'll be accessing all the
records of a given person, identified in "dc:creator", which returns a
XML sorted by "dc:date";
I want to present this data in HTML in a structure similar to the one below:
Type1:
creator, title, date, publisher. (background color for odd row)
creator, title, date, publisher. (background color for even row)
Type2:
creator, title, date, publisher (background color for odd row)
creator, title, date, publisher (background color for even row)
So far I've managed to perform a simple transformation by applying this XSL:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:dc="http://purl.org/dc/elements/1.1/";
xmlns="http://www.w3.org/1999/xhtml";
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
exclude-result-prefixes="dc"
xmlns:def="http://www.openarchives.org/OAI/2.0/";>
<xsl:output method="html" indent="yes"/>
<xsl:template match="/">
<html>
<head>
<link rel="stylesheet" href="oai.css" type="text/css"/>
</head>
<body id="body">
<xsl:for-each select="//def:record">
<!-- Creator data manipulation -->
<xsl:for-each select="def:metadata//dc:creator">
<xsl:value-of select="."/>
,
</xsl:for-each>
<!-- Title manipulation -->
<i>
<xsl:value-of select="def:metadata//dc:title"/>
</i>
.
<br/>
<!-- Publisher manipulation -->
<xsl:value-of select="def:metadata//dc:publisher"/>
,
<!-- Date manipulation -->
<xsl:value-of select="def:metadata//dc:date"/>
.
<br/>
<br/>
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
I've tried to perform the sort by introducing <xsl:sort
select="def:metadata//dc:title"> right next to the <xsl:for-each ...>
tag but it returned a blank document.
How can I do this sorting of the records and how can I identify if the
current record number is even or odd in order to perform diferent
customizations?
Sorry for the lenght of the mail and thanks in advance,
Rolando
