How can I open and read XML document?

XML files are just text files, so any text editor can open them. But reading XML isn't very pleasant; normally you want to use the specific application that understands your particular XML format. But I don't know which app can read msn conversations. In order to make these XML files usable in another app or just more readable, perhaps someone has written a stylesheet (xslt or CSS) that re-formats the XML.

Also, if the actual XML is in fact XHTML, then of course you can read the files in your web browser.

An xml file can be opened using Internet Explorer.

You can probably read them in Notepad enough to figure out what's going on.

To parse them properly, I'm not sure. IE, I think, has some ability to parse XML but generally you need an XSLT translation table for the application. As I recall - I never got this all sorted out in my head.

There are categories of xml archives, yet you could view all of them in notepad. no remember if this is a internet xml report you need to use adobe dreamweaver or yet another internet progression gadget. no remember if this is a musicXML report you could view it in musescore or yet another tune notation or midi introduction gadget
