Either attr="&amp;&lt;>" or attr="&amp;&lt;&gt;" should be produced. 10550 1 mike 2006-07-18 01:02:19 +0000 I think you're right that this is a bug, but to raise a technicality, the issue isn't whether <elem attr="&amp;<>"></elem> is well-formed XML, it's whether it is well formed XQuery. As it happens it is neither. Michael Kay 10554 2 davidc 2006-07-18 10:32:11 +0000 to fix this one and bug #3446 the stylesheet will need to quote <, #9, #10, #13, in addition to & and { that are already handled. In xslt1 that's a deeply nested set of calls to the replace template. If xslt2 isn't an option (which could do this all with a single regexp-replace) another possiblity would be to translate <xqx:attributeValue>&amp;&lt;&gt;</xqx:attributeValue> to <elem attr="{"&amp;<>"}"></elem> ^^ ^^ the extra {"..."} mean that you only need to take care of string-quoting rather than attribute constructor quoting (which I think the stylesheet already gets right) and the XQuery serialiser will then take care of the attribute value quoting rules for < and white space. 10915 3 jim.melton 2006-08-01 01:14:51 +0000 Thanks for your comment. I agree with the comment and have modified the stylesheet to properly escape "<" characters, in addition to the several others identified by bug #3446. I have marked this bug FIXED and encourage you to test the solution and, if you find it satisfactory, mark this bug CLOSED. (I will post the revised stylesheet shortly.) 14179 4 jim.melton 2007-02-25 23:55:46 +0000 Closing bug because commenter has not objected to the resolution posted and more than two weeks have passed.
