The parser returns a tree built during the document analysis. The value +returned is an xmlDocPtr (i.e., a pointer to an +xmlDoc structure). This structure contains information such +as the file name, the document type, and a children pointer +which is the root of the document (or more exactly the first child under the +root which is the document). The tree is made of xmlNodes, +chained in double-linked lists of siblings and with a children<->parent +relationship. An xmlNode can also carry properties (a chain of xmlAttr +structures). An attribute may have a value which is a list of TEXT or +ENTITY_REF nodes.

Here is an example (erroneous with respect to the XML spec since there +should be only one ELEMENT under the root):

In the source package there is a small program (not installed by default) +called xmllint which parses XML files given as argument and +prints them back as parsed. This is useful for detecting errors both in XML +code and in the XML parser itself. It has an option --debug +which prints the actual in-memory structure of the document; here is the +result with the example given before:

DOCUMENT
+version=1.0
+standalone=true
+  ELEMENT EXAMPLE
+    ATTRIBUTE prop1
+      TEXT
+      content=gnome is great
+    ATTRIBUTE prop2
+      ENTITY_REF
+      TEXT
+      content= linux too 
+    ELEMENT head
+      ELEMENT title
+        TEXT
+        content=Welcome to Gnome
+    ELEMENT chapter
+      ELEMENT title
+        TEXT

+      ELEMENT p
+        TEXT

+      ELEMENT image
+        ATTRIBUTE href
+          TEXT
+          content=linus.gif
+      ELEMENT p
+        TEXT
+        content=...

This should be useful for learning the internal representation model.
