MSXML question and Rails



I have an application on a pocket PC that dumps information from a form
into various formats excel, xml, html etc.

XML seems the obvious choice to use, so the user will then submit this
xml document containing the data to a rails web application and the xml
data will be stored in a database to generate reports etc. The data in
the database could then be edited or whatever and then sent back to the
pocket PC via a auto generated xml document.

Pocket PC is a MS application and i noticed this on the manual:

Note: The XML Incoming session options require MSXML, which can be
obtained from Microsoft and is a component of later versions of Internet
Explorer. If problems are experienced using these features, download and
install the MSXML components.

Will i have any issues reading and writing MSXML from my rails app? Any
advice appreciated.
