In my editing environments (BBEdit as well as Eclipse 3.0 w/ XML Buddy under Mac OS X), I received no validation errors. In fact, when I look at the file, I don't see any whitespace at all (I've even tried deleting 'r-f' and re-typing 'transformer-factory', and I still get the same BUILD FAILED errors...). BTW, I notice that the file forrest is complaining about is actually sitemap.xmap, not sitemap-0.5.xmap, which I'm appending to the bottom of this e-mail. It doesn't seem to matter though, as there is no white space there either. I'm stumped! I've ZIP'd up the following files (forrest.properties, sitemap-0.5.xmap, sitemap.xmap, site.xml) and stuck them on my site in case someone thinks they may be useful in helpin resolve these issues: http://homepage.mac.com/webmaestro/xml-fop/xml-fop_files.zip ===== sitemap.xmap ===== //*[local-name() = 'section'] title/text() /site// /@href false false false -//W3C//DTD HTML 4.01 Transitional//EN http://www.w3.org/TR/html4/loose.dtd ISO-8859-1 ISO-8859-1 -//Netscape Communications//DTD RSS 0.91//EN http://my.netscape.com/publish/formats/rss-0.91.dtd ISO-8859-1 ISO-8859-1
