Am I right in my interpretation of the XML standard that attribute content must be normalized by a conforming XML parser and therefore it would never be possible to write an XSL to locate line feeds in attribute values? > > http://www.w3.org/TR/REC-xml/#AVNormalize > > This would give me a strong and invincible reason to tell the CMS programmers to change their stuff. > > - Michael > > -- > As Martin said, you would have to have the line feeds encoded as character references, like and normally, an XML serializer (such as the one used by the Web CMS) would not give you control over how line feeds are serialized (AFAIK). One solution would be to put a non-XML tool in between the CMS and your XSLT, to convert the line feeds to 
 I don't think it would even need to parse the XML; you could just replace every line feed character. So you could use sed. (Somebody correct me if I'm wrong...)
