saveXML: Serializes XSLT-processed document to a file or string

In sckott/sxslt: R extension for libxslt

Description

This method for saveXML writes the XML document stored in the XMLInternalXSLTDocument object either to a file or to an S string (character vector of length 1).

Usage

## S3 method for class 'XMLInternalXSLTDocument'
saveXML(doc, file = NULL, compression = 0,
                                indent = TRUE, prefix = "<?xml version=\"1.0\"?>\n", 
                                doctype = NULL, encoding = "", ...)

Arguments

doc	an object of (S3-style) class XMLInternalXSLTDocument which contains both the XML document reference and the XSLT stylesheet reference. This is typically obtained from a call to xsltApplyStyleSheet.
file	if non-NULL, this is taken to be a string giving the name of the file to which the XML is written. If this is NULL, the XML is written to a string and returned to the caller.
compression	an integer value between 0 and 9 giving the compression level to use when writing the XML to a file. This is ignored if file is NULL.
indent	ignored, but here for compatability with the saveXML generic function in the XML package.
prefix	inherited from the generic function definition and ignored
doctype	inherited from the generic function definition and ignored
encoding	the character string giving the choice of encoding, e.g. "UTF-8", "Latin1".
...	additional parameters pased to methods

Details

This does not use the same mechanism for serializing a XML document as is used in the XML package.

Value

If file is NULL, the result is an S string containing the document. If file is the name of a file, TRUE is returned if the serialization was successful. Otherwise and error is thrown.

Note

In the future, this can be made to support S connections.

Examples

 library(XML)

 doc <- xsltApplyStyleSheet(system.file("examples", "register.xml", package = "Sxslt"),
                            system.file("examples", "register.xsl", package = "Sxslt"), FALSE)

 cat(saveXML(doc))

 outFile <- tempfile()
 saveXML(doc$doc, outFile)

  # to an R string
 saveXML(doc)

## Not run: 
# These files won't exist. Will fix up the example soon!
