Welcome to the Saxon XSLT Processor Service

Wiki MarkupThis local service provides an XSLT Transformation Engine ^\^[1\^]^ for transforming XML-encoded source documents using a supplied XSLT stylesheet. The service functions as a Java servlet and can be invoked using the following syntax:

Where:

• Wiki Markup\[hostname\] -- – The hostname of the Fedora server; default is localhost. Wiki Markup
• \[port-number\] -- – The port number on which the Fedora server is running; default is 8080.unmigrated-wiki-markup
• \[xml-source\] -- – The URL of the XML source file. Wiki Markup\
• [xsl-stylesheet\] -- – The URL of the XSLT stylesheet file.
• clear-stylesheet-cache – An optional parameter indicating if the stylesheet cache is to be cleared. A value of of "yes" signals to clear the stylesheet cache. If the parameter is omitted or has any other value, the stylesheet cache remains untouched.

...

The example below is what needs to be added for each host:port/path combination that the servlet needs to provide credentials for. The param-value is a colon-delimited username and password pair. When the Saxon Servlet needs to access a URL starting with the param-name, it will provide these credentials. Multiple init-param elements may be provided.

<init-param>
  <param-name>credentials for localhost:8080/fedora/getDS</param-name>
  <param-value>backendUser:backendPass</param-value>
</init-param>

Note that the text credentials for must be present at the start of the param-name, and the URL should be supplied without the protocol part (ie localhost:8080/fedora/path rather than http://localhost:8080/fedora/pathImage Removed).

The Saxon Servlet will need to be restarted in order for new values to take effect.

...

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:param name="param1"/>
  <xsl:template match="/">
    <output>
      <xsl:value-of select="$param1"/>
    </output>
  </xsl:template>
</xsl:stylesheet>

...

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:param name="param1"/>
  <xsl:template match="/">
    <output>
      <xsl:value-of select="document($param1)/path/to/element"/>
    </output>
  </xsl:template>
</xsl:stylesheet>

...

By default the Saxon servlet will return a media type of text/html if none has been defined in your stylesheet. If your stylesheet is generating XML you may find it useful to set the media type so the correct type will be returned - for instance to a browser via an object method (disseminator}. To do this include an xsl:output element as a top-level element in your stylesheet, with a media-type attribute defining the media type.

<xsl:output indent="yes" method="xml" media-type="text/xml"/>
