You have enabled short_open_tag option in php (php.ini) which casts <?xml as start of a php block. Either disable short_open_tag or remove the <?xml version="1.0" encoding="UTF-8"?> line (XML prologue) from the XML file of the extension you try to install. I recommend you to disable short_open_tag. It is a bad setting.

Instructions for the XML file
Unzip the extension.
Open the XML file.
Delete the first line <?xml ...
Zip again the extension and try to install it.
