I understand that OpenACS 4.0 uses ns_xml to parse XML files. Since this version has few major bugfixes (including one that can change the behaviour), I enourage everyone using it to upgrade and re-check their scripts.

Release notes

Version 1.2 has been release on 07/04/2001 and contains some major bug fixes, so everyone is encouraged to upgrade. Changes since previous release:

• XSLT support has been added in the form of ns_xml apply_xslt $xslt_doc_id $xml_doc_id and ns_xml parse_xslt ?-persist? command. You need to install libxslt for it to work.
• looks like ns_xml has not been updated to libxml2 which would result in the ns_xml doc root not returning a root but a node below the root. Most visibly, if there was a <!DOCTYPE ..> inside XML doc, you would only get a couple of nodes and not the whole doc. Fixed. May change behaviour of scripts using it.
• ns_xml parse -persistent was broken (would crash) because a hash table for persistent docs has not been initialized. Fixed by initializing hash table.
• ns_xml stats was broken, free() was used to free the memory allocated by ckalloc(). Fixed by calling ckfree().
• many commands didn't check for the number of arguments so they would crash if called incorrectly. Fixed by adding checks for a proper number of arguments.
• fixed Windows compilation issues.
• regression tests were written for the OpenNSD test framework. Tests cover all the issues above and then some.

Sorry for this sort of nagging, you mentioned elsewhere that you also plan to release a Win32 binary of AOLServer 4 beta...
