[MSHADE-149] XmlAppendingTransformer not adequate for aop-ajc.xml files

**[Pascal Pochet](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=p3consulting)** opened **[MSHADE-149](https://issues.apache.org/jira/browse/MSHADE-149?redirect=false)** and commented

When merging aop-ajc.xml files (== merging several AspectJ jars...), XmlAppendingTransformer generates:
\
\
...aspects of jar 1
\
\
...aspects of jar 2
\
...
\
...aspects of jar N
\
\
instead of
\
\
...aspects of jar 1
...aspects of jar 2

...aspects of jar N

\
\

Solution:
add the attached transformer to the list of existing ones.

and in pom.xml:

\
\META-INF/aop-ajc.xml\
\

NB
A more general solution would be to add a parameter to XmlAppendingTransformer to specify the XML level to merge... (maybe as a XPath expression ?)

- [AopAjcXmlResourceTransformer.java](https://issues.apache.org/jira/secure/attachment/12718959/AopAjcXmlResourceTransformer.java) (_3.61 kB_)

Start with the attached AopAjcXmlResourceTransformer.java and the existing XmlAppendingTransformer, then inspect pom.xml for resource transformer configuration. The change is complete when META-INF/aop-ajc.xml entries merge their nested contents into one element instead of producing repeated elements.
