Are you (still) working on this? If not, I am thinking of going ahead
with an implementation based on the following regexp, using a test
for it in the first line of the content:
/^<\?xml[\x20|\x9|\xD|\xA]+(version=("1.0"|"1.1"|'1.0'|'1.1')[\x20|
\x9|\xD|\xA]+)?(encoding=("[A-Za-z][a-zA-Z0-9-_]+"|'[A-Za-z][a-zA-
Z0-9-_]+')\x20|\x9|\xD|\xA]+)?(standalone=("yes"|"no"|'yes'|'no')
[\x20|\x9|\xD|\xA]+)?[\x20|\x9|\xD|\xA]*\?>[\x20|\x9|\xD|\xA]*$/
It should match XML declarations as defined by XML 1.0 and 1.1 specs,
and not be too greedy.
