XSL-Transformation Macro


The XsltMacro allows you to embed the result of an XSL-transformation in a page. It takes two parameters, a stylesheet and a document to transform. These can be an attachment on any wiki-page or ticket, any page from the htdocs area, or any file in the repository (these options are basically same as for Trac's native ImageMacro). For more details see the documentation in the macro.

The macro can either be installed as a simple macro or as a plugin; the use_iframe option (see below) only works when installed as a plugin.

This macro requires that libxml2, libxslt, and their python bindings are installed.


Because a macro's output is embedded in the html of the wiki page, the xsl-stylesheet must not produce a full html page. As an alternative, you can pass the use_iframe option to the macro; this will cause the macro put an <iframe> tag into the page instead of the results from the stylesheet. The stylesheet can (and must) then generate a complete html page.

The downside of iframes is that you need to know the height of the result in order to set the height of the iframe; otherwise you'll either get extra space at the bottom or you'll have to scroll through the frame. The macro generates some javascript to automatically set this height, but that only works if the user has javascript enabled of course.

Bugs/Feature Requests

Existing bugs and feature requests for XsltMacro are here.

If you have any issues, create a new ticket.


To install as a simple macro, just download this file and put it in your wiki-macros directory.

To install as a plugin, download the zipped source from [download:xsltmacro here], change the directory to xsltmacro/0.9, run python bdist_egg, and copy the resulting dist/xslt-0.1-pyX.Y.egg to your plugins directory.


You can check out XsltMacro from here using Subversion, or browse the source with Trac.


The following table is produced with this macro call:

[[Xslt(format.xsl, info.xml)]]
Name Address Email
John Smith 42 Easy St
Mary Francis 1 Heavenly Way

Here's how you would tell it to use an iframe:

[[Xslt(format.xsl, info.xml, use_iframe, if_height=500)]]

Pass (http) request parameters which start with xp_ to the stylesheet as
additional parameters. This can be useful for example to implement paging.

This closes #5275.

A hacked version of able to use external url's as doc or style.

With this version it is possible to do some cheap rss feed integration. Just point the xml to a http:// url and supply a local stylesheet.

Example RSS Feed conversion (please use your own stylesheet):
