Konrad Windszus commented on JCRVLT-391:
----------------------------------------
I made an attempt in https://github.com/apache/jackrabbit-filevault/pull/68.
Some test are failing.
On question around linebreaks between attributes. Why do you expect
{code}
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:jcr="http://www.jcp.org/jcr/1.0";
xmlns:nt="http://www.jcp.org/jcr/nt/1.0";
jcr:primaryType="nt:unstructured">
<a jcr:primaryType="nt:unstructured">
<jcr:xmltext
jcr:primaryType="nt:unstructured"
jcr:xmlcharacters="Hello, World."/>
</a>
</jcr:root>
{code}
instead of
{code}
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:jcr="http://www.jcp.org/jcr/1.0";
xmlns:nt="http://www.jcp.org/jcr/nt/1.0";
jcr:primaryType="nt:unstructured">
<a
jcr:primaryType="nt:unstructured">
<jcr:xmltext
jcr:primaryType="nt:unstructured"
jcr:xmlcharacters="Hello, World."/>
</a>
</jcr:root>
{code}
[~tripod] Under which circumstances should there be a linebreak in front of an
attribute?
> Remove copied classes of Xerces

> Key: JCRVLT-391
> URL: https://issues.apache.org/jira/browse/JCRVLT-391
> Project: Jackrabbit FileVault
> Issue Type: Task
> Components: vlt
> Affects Versions: 3.4.0
> Reporter: Konrad Windszus
> Priority: Major
> Fix For: 3.4.2
>
>
> Currently the classes below {{o.a.j.v.util.xml}} seem to be a copy of Xerces
> classes. Instead of just relying on an old copy one should use a proper Maven
> dependency together with https://maven.apache.org/plugins/maven-shade-plugin/
> or https://bnd.bndtools.org/instructions/conditionalpackage.html to make sure
> update to the latest version is possible.
> Also it needs to be clarified if the embedded Xerces should be listed
> explicitly in
> https://github.com/apache/jackrabbit-filevault/blob/trunk/LICENSE.txt.
> The original intent is stated in
> https://github.com/apache/jackrabbit-filevault/blob/9fa6c72bf4bdf36331b50b9370f3ed826a4622e8/vault-core/src/main/java/org/apache/jackrabbit/vault/util/xml/serialize/XMLSerializer.java#L64.
> The only modifications to the original Xerces were linebreaks after
> attributes and an alphabetic attribute sort order.
> The alternative is to use the {{javax.xml.transform}} API (JAXP
> Transformation API). There is no official way though to control the order of
> attribute, therefore I would recommend to already emit the attributes in the
> correct order instead of reordering them with the output. Controlling the
> indentation of attributes is hard to achieve:
