Patches to XML CopyTag and CopyOfTag to add the "lexical" attribute. The CopyOfTag
patch also replaces the depricated dom4j selectObject function with evaluate. Also a
patch to XML test suite.jelly to test the changes.

Here is an overview of the issue:
---------------------------------------------------------------------
Key: JELLY-28
Summary: Bad entity processing
Type: Bug
Status: Open
Priority: Blocker
Project: jelly
Components:
core / taglib.core
Fix Fors:
1.0-beta-4
Assignee: james strachan
Reporter: Incze Lajos
Created: Thu, 30 Jan 2003 7:44 PM
Updated: Thu, 26 Aug 2004 5:49 PM
Environment: No special environment.
Description:
Have a file, name it a.xml with this content:
-----------------------------
<?xml version="1.0"?>
<!DOCTYPE a [
<!ENTITY x "y">
]>
<a>&x;</a>
-----------------------------
Run the below simple (maven) jelly script:
-----------------------------
<project default="java:jar"
xmlns:j="jelly:core"
xmlns:x="jelly:xml">
<goal name="emnl:test">
<x:parse var="doc" xml="a.xml"/>
<echo><x:copyOf select="$doc"/></echo>
</goal>
</project>
-----------------------------
The result will be this:
-----------------------------
....
emnl:test:
[echo] <?xml version="1.0" encoding="UTF-8"?>
<a>&x;y</a>
BUILD SUCCESSFUL
-----------------------------
I'm aware of the fact that the bug originally comes from dom4j.
The below dom4j program fragment
-----------------------------
....
SAXReader xmlReader = new SAXReader();
Document doc = xmlReader.read("a.xml");
XMLWriter writer = new XMLWriter(System.out);
writer.write(doc);
writer.flush();
....
-----------------------------
will output this result:
-----------------------------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE a><a>&x;</a>
-----------------------------
which is bad (not even well-formed). I've filed this issue
at the dom4j bugtracker
(http://sourceforge.net/tracker/?group_id=16035&atid=116035)
under the number 676427, with some notes one the possible
resolution.
But as we can see, the jelly xml tag adds a twist to the dom4j bug,
it inserts both the entity and the entity value into the tag.
Thanks, incze
