not interpreting the & character

[dreamer]

I write an xml file and i insert a text node using this function

QDomDocument::createTextNode ( const QString & value );

QDomDocument::createTextNode ( const QString & value );

To copy to clipboard, switch view to plain text mode 

I have the necessity to insert the '&' character into the "value" object....
but when i look for the created xml file, it inserts '&' instead of the single '&'.
Any idea??
