Re: [Xmltask-users] Help Needed On XML Tasks

[Adithya V.S.S <ad...@gm...>]

Thank you Brain,

For the first query , my source and destination file are different.

source file is - build-configuration.xml ....something like this

<insert>
<categoryname>Category3</cateogryname>
</insert>
<delete>
<categoryname>Category1</categoryname>
<categoryname>Category2</categoryname>
<delete>

destination file is- workshopCfg.xml

in build-configuration.xml file , I keep the propterties for insert, delete
and modify( just like above example) , when the build.xml file runs it does
the corresponding tasks ( writes / removes the nodes in workshopcfg.xml )
mentioned in the build-configuration.xml file.

And when i run the build.xml once again , it writes Category3 again into the
workshopCfg.xml. If the workShopCfg.xml has the Category3 node, build.xml
should not write it again, Can we control of not writing it in the
destination if exists. ?

2 ) But how can i remove  some specific nodes by reading the
build-configuration.xml , for eg : If i want to remove only Category2 /
Category3 node in the workShopCfg.xml.

 <remove path="/log4j:configuration/category[@name='Category2']"/> -- This
syntax is in build.xml and instead of hardcoding 'Category2' here i want to
dynamically populate the value by reading the buld-configuration.xml. Is
there any way ?

Please help me understand...

Thanks
adithya v.s.s
