Span with two attributes not recognised in the parser for FLSNP files

Hi all,

I have defined the parser to recognise span as an inernal tag using Element span. 

It works fine in the simple cased that we used to have before:

<span class="ui">XXX </span>

Now another attribute has been added and the parser does not understand the element span followed by two attributes.

<span class="ui" xmlns="webaddress">XXX</span>

when I delete xmlns="webaddress", the parser works fine.

Does anyone have a tip how to solve this?

Best regards,

Agija
