xmlparser: read XML-File changes Attribute-Value

[Kemifl]

I don't think it does. According to the spec an attribute value is CDATA by 
default, which means all internal white space should be normalized to a single 
space character, not removed. `xmllint` preserves both spaces:
    
    
    $ echo '<TEST LONG-NAME="this / that">my inner text</TEST>' >test.xml
    $ xmllint test.xml
    <?xml version="1.0"?>
    <TEST LONG-NAME="this / that">my inner text</TEST>
    
    
    Run
