sorry, missed that one

xmlNodePtr pValue = pEvent->children

Sorry, I obviously made this far more confusing than intended

I put the spaces in for readability in the mail
The real xml is on one line so it's very hard to read in plain text
i.e.

<root><firstChild><E><V>48471740</V><T>01c354fc14bb8030</T></E></firstChild></root>

so
pOperationElement is <firstChild>...</firstChild>
pEvent is <E>...</E>
pValue is <V>...</V>
pValueText is 48471740

Another thing which I didn't mention in the original mail is that the 
code in the loop works perfectly for about 50,000 iterations before it 
fails, that is why I asked if there was a limit (I'd have been surprised 
if there was but had to be sure) and also why it looks like heap 
corruption of some sort

Hopefully this makes a bit more sense.
I have tried to split the code out to something I could send but haven't 
had any luck!
