That's what happens with optional D> features. I've replaced it with one that does, and discovered this is perhaps not what I wanted anyway. The new error says the contents of that <envelope> is invalid: org.xml.sax.SAXException: Ill-formed XML document (multiple root elements detected) which is true if value-of is parsing the string. This is what I meant earlier when I said that what I really wanted was an "eval" function to resolve the entities back into the literal chars: value-of/doe is doing this, but also parses the result, so it only works if the markup is legal, and if the markup /was/ legal, I wouldn't have needed to escape it in the first place ;) I haven't actually tried this on the above 'envelope' example, but this is the error I get from my posted example file when I d-o-e the value-of select=//highlight -- value-of will fail because that element contains valid HTML, but invalid XML. When d-o-e is not enabled, the contents of that element is a single text string. When d-o-e is enabled, value-of is (probably correctly) returning a node-set built from parsing the de-escaped element contents. Does this suggest that "value-of" is an inappropriate way to extract markup-like strings from an element (because it parses what it reads) and/or that d-o-e is an inapropriate way to "un-escape" an entity escaped but otherwise literal string? Is 'x-www-form-urlencoding' at the source and display the only way to do this? -- Gary Lawrence Murphy <garym@xxxxxxxxxxx> TeleDynamics Communications Inc Business Innovations Through Open Source Systems: http://www.teledyn.com "Computers are useless.
