Take a look at http://xml.apache.org/xalan-j/extensions.html
If you're using Xalan for the XSLT engine you can call Java APIs from within XSL. -Eric Leblanc Christophe wrote: > hi, > > I wan't to rewrite url created in the portal.

Sure, pass it in as a transformer attribute. Using Xalan elements is a
great approach for things like this. Otherwise you end up having to do
content rewriting which can be tricky and hard to maintain or
front-load all URL generation in the code to pass into the XSLT which
is also not very flexible. The upcoming consistent URL work for uPortal
uses elements to great success for full on URL generation similar to
how portlet URLs are generated.Also you don't need the request to do URL encoding. You could more easily pass in the response encoding as a XSLT parameter Here is an example that uses the default encoding: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0" xmlns:url="http://www.jclark.com/xt/java/java.net.URLEncoder"; exclude-result-prefixes="url"> <xsl:output method="html" indent="yes"/> <xsl:template match="/"> <xsl:variable name="x" select="'encode me #1 superstar?'"/> <xsl:if test="function-available('url:encode')"> <a href="http://www.skew.org/printenv?foo={url:encode($x)}"> <xsl:value-of select="$x"/> </a> </xsl:if> </xsl:template> </xsl:stylesheet> -Eric Gary Weaver wrote: But he's not going to have access to the HttpServletResponse from within the XSL, will he? While he could use java.net.URLEncoder, I think he is saying that he wants to rewrite the URL, which is probably not something possible to be done within the XSL unless somehow it is available during the transformation? And it probably isn't a good place to be doing that if at all possible anyway? |

Also for those interesting in a more complex example, here is the XSLT
part of the code in-development in uPortal for generating URLs in XSL
via a tag-library type system:Unit test for Xalan Element that can generate a portlet URL in uPortals XSLT: http://developer.jasig.org/source/browse/jasigsvn/uPortal/branches/working-3.2-urls/uportal-impl/src/test/java/org/jasig/portal/url/xml/PortletUrlXalanElementsTest.java?r=46648 XSL for test: http://developer.jasig.org/source/browse/jasigsvn/uPortal/branches/working-3.2-urls/uportal-impl/src/test/resources/org/jasig/portal/url/xml/portletUrlTest.xsl?r=46634 Xalan Element code: http://developer.jasig.org/source/browse/jasigsvn/uPortal/branches/working-3.2-urls/uportal-impl/src/main/java/org/jasig/portal/url/xml/PortletUrlXalanElements.java?r=46653 http://developer.jasig.org/source/browse/jasigsvn/uPortal/branches/working-3.2-urls/uportal-impl/src/main/java/org/jasig/portal/url/xml/BaseUrlXalanElements.java?r=46762 -Eric Eric Dalquist wrote: Sure, pass it in as a transformer attribute.
