By "error", I meant my file called error from my first post: error = <<EOF <?xml version="1.0" encoding="UTF-16"?> <document test="yes"> </document> EOF > >> I tried converting all of the files to UTF-8 and they still did not >> work.

I asked for this already (see above). Could you provide a link to a zip file that contains an original input that fails, a re-encoded input file that fails, and an input file that does not fail and a script that loads them? Or, provide a more detailed step-by-step of what you did, e.g.: # poke at the original file to see what it looks like ls -l orig-utf16.xml file orig-utf16.xml wc -c orig-utf16.xml enca orig-utf16.xml head orig-utf16.xml # convert the file iconv -t UTF8 -f UTF16 < orig-utf16.xml > new-utf8.xml # poke at the new file to see what it looks like ls -l new-utf8.xml file new-utf8.xml wc -c new-utf8.xml enca new-utf8.xml head new-utf8.xml # load the files in the script cat rexmltest.rb ruby rexmltest.rb old-utf16.xml ruby rexmltest.rb new-utf8.xml Thanks.
