Absolutely. There's a few gotchas, like if the opening tag ends with />

to recall having to do some strange things with character data fields
when parsing (plus there were probably caveats about escaping quotes in
attribute fields etc. - it's been a while)
Certainly nothing too complex though; error handling of the XML format's
probably the bit that takes most of the effort (coping with malformed
data without crashing the parser or eating up memory etc.)

Yes, true, but I think of XML more as a Web
technology requiring a complex
parsing engine.
Naa, XML parsing is as simple as parsing any other tagged format.
You just start at the beginning of the data stream and wait for
a tag start ('<'), identify the tab, and process the following
information (until the closing tag) as needed. That's all. For
my own little XML data storage I did an XML reader and writer in
Applesoft Basic in a few dozend lines. That's all what's needed.
Shure, if you want to do super-dooper-crunch-every-thing readers,
then it get's a bit more complex, but these are not realy needed
for real world applications (aka the ones realy getting the data
from a media or putting it back).
