Diogo Bacelar Quintela updated JELLY-213:
-----------------------------------------
Attachment: jelly-patch3.patch
Here is patch3 :)
AtributeTag and ElementTag are exactly the same as patch 1
XMLOutput now has a stack of namespaces, and manages the calls to
startPrefixMapping and endPrefixMapping.
It passes common testcases and jelly-xml testcases (haven't tried the others :)
It now generates equivalent outputs in both cases (described in above java
class TestNS)
[equivalent means equivalent xml, not necessarly the same order of attributes].
I've included a new tag, that i mentionated some comments above.
A ReplaceNamespaceTag. As it name implies, it replaces all namespaces from one
uri to another in its body (fromURI and toURI properties).
XMLOutput does it job perfectly, again :)
Ex:
<?xml version="1.0" encoding="UTF-8"?>
<j:jelly xmlns:j="jelly:core" xmlns:x="jelly:xml">
<x:element URI="${ns}" name="test-node">
<x:attribute URI="http://apache/testNS"; name="test:abc"
trim="true">testValue</x:attribute>
<test-subnode attr="test">
<test-anotherSubNode />
<x:element URI="${ns}" name="test-anotherSubNodeAgain">
<x:attribute URI="${ns}" name="other:abc"
trim="true">testValue</x:attribute>
</x:element>
</test-subnode>
<x:replaceNamespace toURI="${ns}">
<test-subnode attr="test">
<test-anotherSubNode />
<x:element URI="${ns}" name="test-anotherSubNodeAgain">
<x:attribute URI="${ns}" name="other:abc"
trim="true">testValue</x:attribute>
</x:element>
</test-subnode>
</x:replaceNamespace>
</x:element>
</j:jelly>
Generates
When 'ns' is empty/inexistent
<test-node xmlns:test="http://apache/testNS"; test:abc="testValue">
<test-subnode attr="test">
<test-anotherSubNode>
</test-anotherSubNode>
<test-anotherSubNodeAgain xmlns:other="" other:abc="testValue">
</test-anotherSubNodeAgain>
</test-subnode>
</test-node>
And when 'ns' if for example 'http://java/ns'
<test-node xmlns:test="http://apache/testNS"; xmlns="http://java/ns";
test:abc="testValue">
<test-subnode xmlns="" attr="test">
<test-anotherSubNode>
</test-anotherSubNode>
<test-anotherSubNodeAgain xmlns:other="http://java/ns"; xmlns="http://java/ns";
other:abc="testValue">
</test-anotherSubNodeAgain>
</test-subnode>
<test-subnode attr="test">
<test-anotherSubNode>
</test-anotherSubNode>
<test-anotherSubNodeAgain xmlns:other="http://java/ns"; other:abc="testValue">
</test-anotherSubNodeAgain>
</test-subnode>
</test-node>
Usefull ? I'll demonstrate with my example.
I am working in ejb plugin for xdoclet-plugins project,
the plugins for xdoclet2 project.
plugin.version.isDtd says true if we need an dtd, false, if we are using a
schema.
If we are using a dtd, we don't need a namespace, if we are using a schema we
need to use 'http://java.sun.com/xml/ns/j2ee' as
default namespace. So plugin.version.ns return null when is a dtd, and
'http://java.sun.com/xml/ns/j2ee' when its not.
With this 'replaceNamespace' tag we can use the default namespace in jelly
script,
(replacing "" for "" let's it exactly the same :D) for dtd output, and when
plugin.version.ns
is http://java.sun.com/xml/ns/j2ee all nodes get automatically updated to that
namespace.
It will be usefull for xdoclet-plugins, and maybe for other projects.
<?xml version="1.0" encoding="UTF-8"?>
<j:jelly xmlns:j="jelly:core" xmlns:x="jelly:xml" xmlns:jsl="jelly:jsl">
<j:if test="${plugin.version.isDtd()}">
<x:doctype name="ejb-jar" publicId="${plugin.version.publicId}"
systemId="${plugin.version.systemId}" trim="true" />
</j:if>
<x:element URI="${plugin.version.ns}" name="ejb-jar">
<j:if test="${!plugin.version.isDtd()}">
<x:attribute URI="${plugin.version.xsiNs}"
name="xsi:schemaLocation"
trim="true">${plugin.version.schemaLocation}</x:attribute>
<x:attribute name="version"
trim="true">${plugin.version.version}</x:attribute>
</j:if>
<x:replaceNamespace toURI="${plugin.version.ns}"
includeAttributes="true">
<enterprise-beans>
<j:forEach var="class" items="${metadata}">
<j:if test="${plugin.shouldGenerate(class)}">
<entity>
<ejb-name>${plugin.ejbUtils.getEjbName(class)}</ejb-name>
....
</entity>
</j:if>
</j:forEach>
</enterprise-beans>
</x:replaceNamespace>
<j:import uri="org/xdoclet/plugin/ejb/descriptor/entity-beans.jelly"
inherit="true"/>
</x:element>
<!--</ejb-jar> -->
</j:jelly>
If this patch is usefull as a full (as i think it is),
i'd be happy to known when it gets added to jelly project, and jelly-xml.

> I tried to find some info googling around and in the faq and couldn't find

> I need to generate the following xml (it's a sample off course), to support

> ------------------------------------------------
> <NodeName
> xmlns="http://blah/bleh";
> xmlns:xsi="http://www.w3.org/2001/XMLSchema";
> xsi:schemaLocation="http://blah/blehSchemaLocation";>
> <!-- Other content here -->
> </NodeName>
> ------------------------------------------------
> After several tries and some inconsistent behaviour, I thought the following
> jelly excerpt should be close to the solution, however "xml:attribute"
> doesn't support namespaces values.

> <j:jelly xmlns:j="jelly:core" xmlns:x="jelly:xml">
> <x:element URI="${myns}" name="NodeName">

> ${myschemaloc}
> </x:attribute>
> <!-- Other content here -->
> <x:element>

> Where

> "myschemaloc" is for example http://blah/blehSchemaLocation
