The general rule is this:

Write the declaration out, then read it backwards to determine what is 
const. In this case, I believe the declaration would be "const xmlNode 
*", so reading it backward says that it's a pointer to a xmlNode that is 
const. A const pointer would be "xmlNodePtr const node"
