[xml] Pretty print in libxml2

[shtil comcast net]

Hi,

I wonder if there is a way to pretty print xml.

Referring to the examples for xmlWriter I want 

<?xml version="1.0" encoding="ISO-8859-1"?>

<EXAMPLE><!--This is a comment with special chars: <äöü>--><ORDER version="1.0" xml:lang="de"><!--This is another comment with special chars: <äöü>--><HEADER><X_ORDER_ID>0000053535</X_ORDER_ID><CUSTOMER_ID>1010</CUSTOMER_ID><NAME_1>Müller</NAME_1><NAME_2>Jörg</NAME_2></HEADER><ENTRIES><ENTRY><ARTICLE>&lt;Test&gt;</ARTICLE><ENTRY_NO>10</ENTRY_NO></ENTRY><ENTRY><ARTICLE>&lt;Test 2&gt;</ARTICLE><ENTRY_NO>20</ENTRY_NO></ENTRY></ENTRIES><FOOTER><TEXT>This is a text.</TEXT></FOOTER></ORDER></EXAMPLE>

to look like:

<?xml version="1.0" encoding="ISO-8859-1"?>

<EXAMPLE>

  <!--This is a comment with special chars: <äöü>-->

  <ORDER version="1.0" xml:lang="de">

    <!--This is another comment with special chars: <äöü>-->

    <HEADER>

      <X_ORDER_ID>0000053535</X_ORDER_ID>

      <CUSTOMER_ID>1010</CUSTOMER_ID>

      <NAME_1>Müller</NAME_1>

      <NAME_2>Jörg</NAME_2>

    </HEADER>

    <ENTRIES>

      <ENTRY>

        <ARTICLE>&lt;Test&gt;</ARTICLE>

        <ENTRY_NO>10</ENTRY_NO>

      </ENTRY>

      <ENTRY>

        <ARTICLE>&lt;Test 2&gt;</ARTICLE>

        <ENTRY_NO>20</ENTRY_NO>

      </ENTRY>

    </ENTRIES>

    <FOOTER>

      <TEXT>This is a text.</TEXT>

    </FOOTER>

</ORDER>

</EXAMPLE>
