Mon Dec 14 19:39:58 CET 2015

Hi All,

I am new to wonderful world of R, I am stuck at one problem.

I need to print the minified XML string in tree format, i have tried below
code:

ex  <- "<note><to>Tove</to><from>Jani</from><heading>Reminder</heading><body>Don't
forget me this weekend!</body></note>"> > XML::xmlParse(ex)<?xml
version="1.0"?><note>
  <to>Tove</to>
  <from>Jani</from>
  <heading>Reminder</heading>
  <body>Don't forget me this weekend!</body>
</note>

and it is working fine for this short XML but it doesnt work for the XML
like:
