Transform an XML document by applying an XSL stylesheet. Usually returns the
transformed xml_document, unless the stylesheet has
<xsl:output method="text"> in which case we return a text string.
Arguments
- doc
xml document as returned by xml2::read_xml
- stylesheet
another xml document containing the XSL stylesheet
- params
named list or vector with additional XSLT parameters
Details
This implementation supports XSLT 1.0 features plus most of the EXSLT set of processor-portable extensions functions. Unfortunately XSLT 2.0 or 3.0 features are only available in proprietary libraries and currently unsupported. However XSLT 2.0 is not widely adopted anyway because it is unavailable in most browsers.
Examples
doc <- read_xml(system.file("examples/cd_catalog.xml", package = "xslt"))
style <- read_xml(system.file("examples/cd_catalog.xsl", package = "xslt"))
html <- xml_xslt(doc, style)
cat(as.character(html))
