newRoot :: XmlTrees -> XmlTree

creates a new document tree with empty contents.

  • 1.parameter al : the attribute list for the root node

see also : newDocument

mkRootTree :: XmlTrees -> XmlTrees -> XmlTree

create a document root tree.

  • 1.parameter al : the attribute list for the root. This list must contain at least an attribute "source" that contains the URI of the document to be processed
  • 2.parameter cs : the list for the document content
  • returns : the document root
mkXTextTree :: String -> XmlTree

  • 3.parameter ds : the possibly empty list of components for the DTD part
  • returns : the tree with the composed DTD part
mkXAttrTree :: String -> XmlTrees -> XmlTree

create an attribute tree as part of a tag attribute list of tag nodes

  • 1.parameter al : the attribute name
  • 2.parameter av : the attribute value as tree list, usually containing a single text node
mkQAttrTree :: QName -> XmlTrees -> XmlTree
Qualified version of mkXAttrTree
mkXNsAttrTree :: String -> String -> XmlTrees -> XmlTree

create an attribute tree with a namespace

  • 1.parameter al : the attribute name
