You chose to add spaces and breaks to your HTML to make it more 
readable and the bandwidth apparently was not a concern then.  Since 
XML is also supposed to be readable, why insist on 1 line XML file? 

The sequences: 
   A: "this word" 
   B: "thatnword" 
are exactly the same length.  So A (1 line) is not more "compressed" 
than B (2 lines).  Sure you may save a few spaces it you delete 
indentation spaces, but that is probably nominal.  I dont necessarily 
buy "shorter, cleaner and thus, better". 
If I have an XML file that I need to view or edit, then I like to have 
proper indentation for readability.  If the XML is only going to be 
short lived and consumed by a computer, then I make sure it is at 
least well-formed (if not valid) and pretty much leave the spacing up 
to the tools ... they usually do the right thing(tm).

Sure it is.  In fact, there are a lot of ways to do this.  Here's one 
way off the top of my head (I'm sure the list can supply 100 others!): 
   <xsl:template match="text()[ not(parent::*/@notnormalize='false') ]"> 
      <xsl:value-of select="normalize-space(.)" /> 
Have fun,
