processXInclude {XML} | R Documentation |
Perform the XInclude substitutions
Description
This function and its methods process the XInclude directives
within the document of the form <xi:include href="..."
xpointer=".."
and perform the actual substitution.
These are only relevant for "internal nodes" as generated
via xmlInternalTreeParse
and
newXMLNode
and their related functions.
When dealing with XML documents via xmlTreeParse
or xmlEventParse
, the XInclude nodes are controlled
during the parsing.
Usage
processXInclude(node, flags = 0L)
Arguments
node |
an XMLInternalDocument object or an XMLInternalElement
node or a list of such internal nodes,
e.g. returned from |
flags |
an integer value that provides information to control how the XInclude substitutions are done, i.e. how they are parsed. This is a bitwise OR'ing of some or all of the xmlParserOption values. This will be turned into an enum in R in the future. |
Value
These functions are used for their side-effect to modify the document and its nodes.

processXInclude(doc)
cat(saveXML(doc))
f = system.file("exampleData", "include.xml", package = "XML")
doc = xmlInternalTreeParse(f, xinclude = FALSE)
section1 = getNodeSet(doc, "//section")[[1]]
