REXML - controlling whitespaces and inserting CR

ruby-talk
1

Hello All,

I have an XML file containing this
<properties>
    <property key="ABC">
        <value xml:lang="de">Description de</value>
        <value xml:lang="en">Description en</value>
    </property>
    <property key="XYZ">
        <value xml:lang="de">Description de</value>
        <value xml:lang="en">Description en</value>
    </property>
</properties>

I made a code to add a new <value> tag to each <property>.
The part of code is:

require "rexml/document"
include REXML
...
...
      pval = Element.new("value")
      pval.add_attribute("xml:lang","fr")
      pval.add_text("Description fr")
      fproperty.elements << pval
fproperty is the node object

My final XML file looks like this:

<properties>
  <property key="ABC">
    <value xml:lang="de">Description de</value>
    <value xml:lang="en">Description en</value>
    <value xml:lang="fr">Description fr</value></property>
  <property key="XYZ">
    <value xml:lang="de">Description de</value>
    <value xml:lang="en">Description en</value>
    <value xml:lang="fr">Description fr</value></property>
</properties>

One "TAB" is inserted for each 4 spaces which were in the original file.
How to avoid this?
And how to add a CR to the new element?

Thanks for your help, I'm a very newby

I think, you will have to create your own formatter - or use a
different one for output. You'll find some explanation in the REXML
documentation.

Kind regards

Thank you Robert for your reply.
I am willing to write my own formatter but despite I read some REXML
docs, I don't know where to begin. :smiley:

This is really my first day with ruby;
concerning REXML I'll be happy to be pointed to some samples.

In advance Thanks to All,

Charles

Great thank you.

Afternoon,

You might find it just as easy to take that output and push it out to a file
and then hit it with xmlindent (http://xmlindent.sourceforge.net/) it will
do exactly what you want. No sense in re-inventing the wheel.

Yes John.
It seems like it will ideally fit my need.

Thanks a lot.
