[TYPO3-core] RFC: Bug 3994: OpenOffice.org files cannot be indexed by class.external_parser.php

[Michael Stucki]

This is a SVN patch request.

Problem:
There are some bugs in the [case 'sxw':] - section of the readFileContent() - 
function:

$cmd = $this->app['unzip'].' -p '.$absFile.' content.xml';

This doesn't work with whitespaces in the filename. Same with unzipping 
meta.xml.
 
Solution:
$out must be unset() before the second exec()-call, otherwise $meta_xml will 
contain the content of both content.xml and meta.xml

Branches:
TYPO3_4-0 / Trunk

Comments:
Thanks to Robert Fink
