This document has errors that must be fixed before
using HTML Tidy to generate a tidied up version.



So, Is this problem caused by xsltproc haven't installed ? when I want to install xsltproc, I found so many libs required.. seem a little complicated. Could you help me about the installation.

Thanks, Tod.

I have installed tidy.

Hi Tod,

the tool works by converting HTML rendered by trac to HTML which Word can read. Because Word has a specific HTML, there has to be a conversion from one HTML to another. The conversion is carried out by using a XSL-transformation for which the use of an XSLT processor as like as xsltproc is essential. I have chosen xsltproc because it is likely to be installed on linux machines. You might change to a different XSLT processor which has fewer dependencies on your system, but this might require adjustments of the parameters.

Tidy is just used for cleaning up the trac HTML, as the XSLT processor (at least xsltproc I am speaking about) needs strict HTML for the conversion. To ensure this, the output is being cleaned by Tidy (trac core produces strict HTML as far as I know, but there might be additional content by plugins, so I decided to use Tidy).

Oh.. now I see you get an error with Tidy. I have overseen that on the first glance. The first error looks like you haven't installed Tidy, but I think you catched it up later (your comment). The command you executed is definitely incorrect, because you tried to process the XSL stylesheet with tidy. 'htmlfilepath' refers to the HTML file contains the output of trac.

So there are two options. Stick with xsltproc or modify the program so that it uses a different XSLT processor. I am sorry that the installation carries out this complicated, that was exactly the opposite of what I intended choosing xsltproc. If you find a better solution, please feel free to modify and improve this plugin, as this was my first experience with trac plugins and python scripting at all.

Cheers, Lucas

I have encountered the same error on a freebsd system. I installed all necessary packages from ports, and tidy is available in the command line. But I get "127 - tidy not found" error. I can't even imagine what is wrong...

regards, alex

Could it be a usr directory problem? I know very little about unix - but if the web server runs under a different user than you - it may have a different path?

Resolution: → fixed new → closed

Hopefully the changes checked in with [5406] allow you to get rid of this error. You can now specify the path to tidy - and the plugin checks that it is actually correct.
