Amen. Unfortunately many people don't think before creating XML.

You are not the clueless one: that is your client, unfortunately.

When I get a large quantity (or many repeat instances) of files like
this, where the markup itself is regular enough to be SGML, but the
design defective, I resort to invoking omissibility. This SGML document:

<!doctype content [
<!element content - - (status,faxes)>
<!element status - - (#pcdata)>
<!element faxes - - (fax)+>
<!element fax o o (faxid,date,source,destination,status)>
<!element faxid - - (#pcdata)>
<!element date - - (#pcdata)>
<!element source - - (#pcdata)>
<!element destination - - (#pcdata)>
]>
<content>
<status>ok</status>
<faxes>
<faxid>21404974</faxid>
<date>2012-01-05 07:34:10</date>
<source>5194852368</source>
<destination>8885216725</destination>
<status>read</status>
<faxid>23223059</faxid>
<date>2012-03-01 07:27:52</date>
<source>5194211862</source>
<destination>8885216725</destination>
<status>new</status>
<faxid>23223164</faxid>
<date>2012-03-01 07:29:45</date>
<source>5194211862</source>
<destination>8885210692</destination>
<status>new</status>
<faxid>23224287</faxid>
<date>2012-03-01 07:51:07</date>
<source>8885216725</source>
<destination>8885210692</destination>
<status>new</status>
</faxes></content>

can be processed with sgmlnorm to normalize it so that the missing <fax>
and </fax> elements are inserted. Usually this is only worth doing for a
workflow, so that it will create fully-normalized SGML which an XML
processor will accept.

That's fine. XML doesn't need to be pretty-printed unless you want to
show it to a human. As Martin indicated, there are ways to pretty-print
it if you need (and from a later post you discovered Tidy). But it's
usually more effective to concentrate on making the markup processable
rather than on making it look attractive.
