Examples

First let's include a simple small file:

<kw_include_file>url=http://public.kitware.com/cgi-bin/viewcvs.cgi/*checkout*/README.txt?root=kwGrid</kw_include_file>

...is rendered as: <kw_include_file>url=http://public.kitware.com/cgi-bin/viewcvs.cgi/*checkout*/README.txt?root=kwGrid</kw_include_file>

Now for something more complex. Note that the whole documentation above this section is included straight from the extension code itself ! Here is how it is done:

<kw_include_file>url=http://public.kitware.com/cgi-bin/viewcvs.cgi/*checkout*/scripts/media-wiki-extensions/kwIncludeFile.php?content-type=text%2Fplain&root=kwGridWeb|pre=0|wiki_markup=1|collapse_par=1|preg_match=/.*\/\*\s*(==.*?)^\*\//sm</kw_include_file>

The hairy URL is followed by several options. The pre=0 parameter means that we do not want the text to be inserted verbatim inside PRE.../PRE tags. The wiki_markup=1 parameter specifies that the text is to be interpreted as Wiki markup. The (optional) collapse_par=1 parameter helps the Wiki engine by collapsing lines into paragraphs. The preg_match parameter specificies a regular expression that is used to extract only the documentation portion of the remote file: nothing fancy here, we are just looking for the string starting with == right inside a PHP comment /* ... */.
