xml2array() was designed for parsing flexform values. I have indeed seen 
problems with tags spread over multiple lines if they only contain a value:

<tag>
   value
</tag>

went wrong and

<tag>value</tag>

was no problem.

That parameter can be used to pass a namespace to the function. The xml 
parser that is used apparently returns the tag names including the 
namespace prefix. If a tag is found that starts with the namespace it's 
removed before making an entry in the array.

Perhaps a different XML parser is more useful in this case...
