Re: [xml] Possible bug on content addition then node deletion.

[Jose Commins <axora myrealbox com>]

	Well, after testing and manual walking through the tree with a 
debugger, I noticed the difference - your code indeed works, and so 
does mine if I create the doc your way.  But, I use xmlReadMemory in my 
code, and it produces this structure if I use the xml example as an 
input:

NODE <Something> = (name->'Something', content->0):

NODE 'Dogs usually say bark but I say' = (name->'text', content->'Dogs 
usually bark but I say'):


....  and so on.

	So xmlReadMemory does not join content to tags even if it is adjacent 
to them.  Which explains the behaviour observed - the content ('Dogs 
usually say bark but I say') in your example actually *belongs* to 
'Something' as content; with xmlReadMemory it isn't, it is separated 
into a separate text node.
        I shall have to concatenate adjacent text nodes myself, then...


Regards,
                Jose.
