I mentioned a while ago something about trimming all whitespace from
metadata values, but that was rejected because some data might need that
whitespace. I also added support to auto trim attribute values from
jboss.jcml.
Now I would like to suggest changing things such that all leading
and trailing whitespace is truncated for all attribtes (jcml and metadata)
unless the data is enclosed in a CDATA element.
Initially I was not sure if this was possible, but I just check and we can
detect if a node is a CDATA via the Node.getNodeType() ==
Node.CDATA_SECTION_NODE.
Lets assume that there is no autoTrim in ConfigurationService and we have a
mbean that looks like this:
<mbean code="org.jboss.web.WebService"
name="DefaultDomain:service=Webserver">
<attribute name="Port">
8083
</attribute>
</mbean>
The value of Port should resolve to "8083".
<mbean code="org.jboss.web.WebService"
name="DefaultDomain:service=Webserver">
<attribute name="Port">
<!CDATA[8083]]>
</attribute>
</mbean>
The value of Port should still resolve to "8083", since we can cast aside
the first node, since it is empty and its sibling is a cdata.
To make this work, some modifications will be required to look for empty
nodes with siblings that are CDATA. We could also support comments inside,
such that this would also work:
<mbean code="org.jboss.web.WebService"
name="DefaultDomain:service=Webserver">
<attribute name="Port">
<!-- use this port -->
8083
</attribute>
</mbean>
Any ways, I think that this would be very, very helpful to allow more
freedom with respect to usage of XML syntax, and provide a mechanism to
indicate that whitespace should not be trimmed.
Any comments?
