[xml] xmlGetProp

["Theodore H. Smith" <delete elfdata com>]

Hi people,

Is there a way to get an XML attribute, without having to worry about  
xmlFree? That is, get the actual char* with your xml tree node  
structure.

I'm just worried I may xmlGetProp one day and forget to xmlFree. Not  
having to worry about memory issues is always a good thing. The way  
that we don't need to xmlFreeNode on the xml nodes we get from a tree  
is nice, some similar behaviour like that for properties would be good.
