Hello,
I have found in the mailing archive a discussion regarding to the
outputter attribute of the xmltask, that when its value is "simple" (or
e.g. "simple:4") than the xmltask does not work properly for XMLs
defined accroding to XSD schemas. But I could not find the solution for
it (I mean in the archive). Could somebody confirm if this probelm is
already solved or not? I have used the latest xmltask jar, but it does
not look solved. Please look at examples:
ant1.6.5, xmltask-v1.15.1.jar, jdk 1.6.0
##### Example1 (Simply reads the source XML and writes it out to the
same file):
Source XML (src):
==========
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd";>
</beans>
Task to modify the source XML (with same source and destionation
location):
========================================================
<xmltask source="${src}" dest="${src}" outputter="simple:4" >
</xmltask>
Logs snippet from the modify process:
============================
[xmltask] Reading D:\Temp\applicationContext.xml
[xmltask] Executing xmltask 1.15.1
[xmltask] Processing D:\Temp\applicationContext.xml into

[xmltask] Using predefined xml catalog (Question: Should be used
the xmlcatalog task also for XMLs defined according to XSD schemas?)
[xmltask] Normalizing resultant document
[xmltask] Indenting resultant document
Result XML processed with xmltask (added some extra namespaces):
================================================================
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";></beans>
END of Example1
############################################################
##### Example2 (It reads the beans from source XML (bean after bean) and
inserts them to the destination XML):
Source XML (src):

Destination XML before xmltaks processing (dest):
================================

Ant script to read beans from the source XML (bean after bean) and
insert them to dest XML:

The result is similar as in example 1:The 2nd insert fails, since the
first insert "corrupts" the destination XML. Of course this works
without the outputter attribute in the xmltask or within it with value
"default", but in this case the xml is not formatted :-(.
Thanks in advance. Regards, Gabo.
