NAME

EPrints::Plugin::Export::XSLT - XSLT-based exports


SYNOPSIS

Create a file in Plugins/Export/XSLT/ called 'Title.xsl' containing: 

<?xml version="1.0"?>

<xsl:stylesheet
	version="1.0"
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	ept:name="Titles"
	ept:visible="all"
	ept:advertise="1"
	ept:accept="list/eprint dataobj/eprint"
	ept:mimetype="application/xml; charset=utf-8"
	ept:qs="0.1"
	xmlns:ept="http://eprints.org/ep2/xslt/1.0"
	xmlns:ep="http://eprints.org/ep2/data/2.0"
	exclude-result-prefixes="ept ep"
>

<xsl:param name="results" />

<xsl:template match="text()" />

<xsl:template match="ept:template">
<titles><xsl:value-of select="$results"/></titles>
</xsl:template>

<xsl:template match="/ep:eprints/ep:eprint">
  <title><xsl:value-of select="ep:title"/></title>
</xsl:template>

</xsl:stylesheet>



DESCRIPTION

This export plugin allows you to use XSL Transforms to export data from EPrints. The plugin is fed EPrints XML and can output any resulting data supported by XSLT.

This is the inverse process of EPrints::Plugin::Import::XSLT.


Headers and Footers

You can specify a template to use for your output: 

  <xsl:template match="ept:template">
    <html>
      <body>
        <xsl:value-of select="$results"/>
      </body>
    </html>
  </xsl:template>

Note: you can output unbalanced XML by using disable-output-escaping: 

  <xsl:template match="ept:template">
    <xsl:text disable-output-escaping="yes">
      &lt;html&gt;
        &lt;body&gt;
    </xsl:text>
    <xsl:value-of select="$results"/>
  </xsl:template>


Controlling XML Declarations

If your stylesheet outputs XML (the default): 

  <xsl:output method="xml"/>

The XML declaration will only be outputted once at the start of the export, regardless of how many records there are.

To output as XML and suppress the XML declaration entirely define an empty prefix: 

  <xsl:stylesheet
    xmlns:ept="http://eprints.org/ep2/xslt/1.0"
    ept:prefix=""
  >


PLUGIN OPTIONS

All attributes on <xsl:stylesheet> that are in the EPT namespace are treated as plugin parameters. In addition to those parameters used by all EPrints::Plugin::Export plugins XSLT uses: 

  prefix
    Value is printed before any content (defaults to XML decl.)
  postfix
    Value is printed after any content.


STYLESHEET PARAMETERS

The following parameters are passed to the transform for each item: 

  total
    Total items in result set.
  position
    1-indexed position in result set.
  dataset
    Base id of the item's dataset (e.g. "eprint").


EXTENDED FUNCTIONS

The standard EPrints global extended XPath functions are supported, see EPrints::XSLT.
