ROM Hack Trying to change Pokemon Diamond text

[colt05]

Hi.
I am using thenewpoketext and I am getting this error:

File "<string>", line 123, in <module>
File "<string>", line 59, in Rewrite
File "thenewpoketext\buildthenewpoketext\out1.pyz/pokexml", line 28, in __init
__
File "thenewpoketext\buildthenewpoketext\out1.pyz/xml.dom.minidom", line 1913,
in parse
File "thenewpoketext\buildthenewpoketext\out1.pyz/xml.dom.expatbuilder", line

207, in parseFile
xml.parsers.expat.ExpatError: not well-formed (invalid token): line 69660, colum
n 5

Is the encoding on the XML broken after I save it?
Thanks!
