| newXMLDoc {XML} | R Documentation |
These are used to create internal `libxml' nodes
and top-level document objects
that are used to write XML trees.
While the functions are available,
their direct use is not encouraged.
Instead, use xmlTree
as the functions need to be
used within a strict regime
to avoid corrupting C level structures.
newXMLDoc(dtd, namespaces=NULL) newXMLNode(name, ..., attrs = NULL, namespace="", doc=NULL)
dtd |
the name of the DTD to use for the XML document. |
namespaces |
a named character vector
with each element specifying a name space identifier and the
corresponding URI for that namespace
that are to be declared and used in the XML document, \
e.g. c(shelp = "http://www.omegahat.org/XML/SHelp") |
name |
the tag/element name for the XML node |
... |
the children of this node. These can be other nodes created earlier or R strings that are converted to text nodes and added as children to this newly created node. |
attrs |
a named list of name-value pairs to be used as attributes for the XML node. |
namespace |
the short or alias for the namespace to use for this XML node |
doc |
the XMLInternalDocument object created with
newXMLDoc that is used to root the node. |
These create internal C level objects/structure instances that can be added to a libxml DOM and subsequently inserted into other document objects or ``serialized'' to textual form.
Each function returns an R object that points to the
C-level structure instance.
These are of class XMLInternalDocument
and XMLInternalNode, respectively
These functions are used to build up an internal XML tree. This can be used in the Sxslt package (http://www.omegahat.org/Sxslt) when creating content in R that is to be dynamicall inserted into an XML document.
