[phpXML] Re: [phpXML] miss-match

[<tom...@di...>]

I was initially thrown off by the 'trivialness' of the example but when I 
look at how you intend to process the file it seems to cry out for a 
different structure altogether.

Is it not true that _if_ there are children _then_ the children should 
stand as elements of the parent?  ((then the other 'content' is/are really 
attributes of the parent))

That would say to me that  the example being discussed could (should?) 
better be constructed like

<blah1 precursor="Text" postcursor="text.">
    <blah2>more</blah2>
</blah>

Wouldn't that be more parallel to the processing that you intend to do to 
the file?

my 2cents
