Updated by: rrichards@php.net
Reported By: gk at proliberty dot com
-Status: Verified
+Status: Bogus
Bug Type: XML related
Operating System: linux 2.4.18
PHP Version: 4.3.3RC2-dev 5.0.0b2
New Comment:
Whitespace after the target are removed - normal behavior.
The linespacing (between the closing bug tag and the PI) is screwed up
as your xml is not well formed.
As far as whitespaces in the variable producing blank output, check the
return error. The xml declaration is probably screwed up to produce no
output. This was the only instance I could reproduce no output.

There is another issue here that I've come across while testing the
bug. If the variable containing the XML data contains any white space
such as \n, \r or ' ', the resulting output is blank.
