Unexpected replacement

Good day sedders,

I am trying to write a simple batch file to do some replacements 
within an XML file using GNU sed version 4.0.7 on Windows XP.

Here is the line (#62)I'm targeting:

<menutree:TREENODE TEXT="Updates" EXPANDED="true" 
TREENODESRC="xmlfiles/Menu.xml" IMAGEURL="images/folder.gif" 
EXPANDEDIMAGEURL="images/folderopen.gif" FILENAME=""/>

Here is the snipit from the batch file that invokes sed:

SET /P Choice=Enter tree node text and press Enter:
sed 62s/TREENODE\x20TEXT.*EXPAND/TREENODE\x20TEXT\x3D\x22"%
Choice%"\x22\x20EXPAND/  <..\Incrementals.html > tmp.txt

My expectation is that user input text from the variable %Choice% 
replaces "Updates". However, given an input of: New Node Name, here 
is what ends up in tmp.txt:

<menutree:TREENODE TEXT="New Node Name" 
EXPANDEDIMAGEURL="images/folderopen.gif" FILENAME=""/>

Why is sed not stopping at the first occurence of EXPAND?
I'm sure that the answer is simple, but I just can't see it.

Thanks,

Greg
