Hi All,
I updated a tool that can be downloaded from ESRI ArcScripts: http://arcscripts.esri.com/details.asp?dbid=12766
Hope to get feedback from a.o. MapServer users.
Updated version released on 07-01-2007 (first release: May 2003)
After over 9000 downloads I added the option to create configuration files for other Web Map Servers like MapServer (http://mapserver.gis.umn.edu) besides the already supported ArcIMS! You can extend this to other formats by adding new XSLT transformation stylesheets (see below 'Adding other formats')
The configuration files for ArcIMS and for MapServer are focussed on creating Open Geospatial Consortium compliant Web Map Services (OGC-WMS).
The files generated for MapServer can be customized by editing the "resoures/_MXDtoMap.xsl" file. The default form is particularly focussed on users that publish metadata and services through GeoNetwork opensource (http://geonetwork-opensource.org).
This tool converts ArcMap views (all layers in the view) into ArcIMS (ArcXML .axl) and MapServer (.map) configuration files, both for shapefiles and for raster files.
The conversion to MapServer is still under development and good improvements are very welcome!
I have basically had two problems reported. I hope these are fixed through this release.
This release fixes:
- Issues with ArcMap 9.2
- Allows you to convert Maps with up to 500 layers instead of 30.
Otherwise no changes have been made.
This tool is free and open source software released under the LGPL license. You can find the source code at http://sourceforge.net/projects/arcmaptools
I would appreciate an e-mail if you like it

Adding other formats:
You can add other output formats by creating XSLT documents that convert the AXL output generated by default. To do this, save the created XSLT in the resources folder and add a format Element to the formats.xml file that contains the parameters needed for that type of configuration file.
For example:
<format>
<ext>*.sld</ext>
<filter>Style Layer Description files (*.sld)|*.sld</filter>
<xslt>_MXDtoSLD.xsl</xslt>
</format>
Good luck,
