The javax.xml.transform.URIResolver Class

Members

Overview

This is the interface responsible for URI resolution, and is analogous to the SAX EntityResolver interface. This interface allows URIs found in XML constructs like xsl:import and xsl:include to be handled. It has only one method resolve(), which returns javax.xml.transform.Source. You can instructtransformer to search for the specified document in various locations when a particular URI is encountered. For example, when an include of the URI http://www.topxml.com/header.xsl is encountered, you might instead return the local document Localheader.xsl and prevent the need for network access.

Method Overviews

The only method in this interface is resolve(String href,String base). This method is called by the processor when it encounters an xsl:include, xsl:import, or document() function.  

Example of how to use resolve(String href,String base)

Your main stylesheet contains <xsl:include href="http://www.topxml.com/header.xsl"/>. During processing, when it encounters this href, you want to use your local stylesheet. “Localheading.xsl”.

public Source resolve(String href, String base)

  {

    System.out.println("Href :"+href);

    System.out.println("Base :"+base);

    Source source = null;

    if(href.equals("http://www.topxml.com/header.xsl"))

    {

      source = new StreamSource("E:\\topxml\\Localheading.xsl");

      return source;

    }

    if(source == null)

    {

      source = new StreamSource("E:\\topxml\\Default.xsl");

    }

    return source;

  }

The above method first compares the href. If it matches your criteria, then it creates a new source so your transformer uses this source in stead of http://www.topxml.com/header.xsl .

URIResolverImpl uriResolver = new URIResolverImpl(); //This class implements URIResolver.

tFactory.setURIResolver(uriResolver);
