Just before submitting this comment i found documentation on it
in the upgrade instructions.. maybe a good idea to still add a
FAQ entry since new users aren't likely to read upgrade instructions.
The main document should also be updated ("the tree output" section).

Sorry to bother you all with this, but shouldn't this question
deserve an entry in the FAQ? Note that i started out with libxml
today (and XML in general) so forgive my ignorance.

The problem is simple; how significant is whitespace between tags?
For example, the libxml docs suggest that the following XML:

<head>
   <title>Welcome to Gnome</title>
</head>

should create an internal DOM tree like:

ELEMENT head
  ELEMENT title
    TEXT
    content=Welcome to Gnome

instead the xmllint util packed with my libxml 2.2.4 version
gives:

ELEMENT head
  TEXT
  content=
  ELEMENT title
    TEXT
    content=Welcome to Gnome
  TEXT
  content=

A way to ignore the whitespace is to call xmlKeepBlanksDefault(0);
before parsing.

shouldn't this be noted in a FAQ or other documentation??
