Hello all,

I am trying to move from .Net System.Xml to libxml2 and i would like
to know how can i print the element markup representing of the current
node and all its child nodes using libxml2. coming from .Net
background i could do this by System.Xml.XmlNode.OuterXml of the
current node. I tried  to read the document on xmlsoft.org however i
is very confusing to me . therefore, if anyone could help me with this
or point me to the right direction
