xmlCleanNamespaces

Remove redundant namespaces on an XML document

Description

This is a convenience function that removes redundant repeated namespace definitions in an XML node. It removes namespace definitions in nodes where an ancestor node also has that definition. It does not remove unused namespace definitions.

This uses the NSCLEAN option for xmlParse

Usage

xmlCleanNamespaces(doc, options = integer(), out = docName(doc), ...)

Arguments

`doc`	either the name of an XML documentor the XML content itself, or an already parsed document
`options`	options for the XML parser. `NSCLEAN` is added to this.
`...`	additional arguments passed to `xmlParse`
`out`	the name of a file to which to write the resulting XML document, or an empty character vector or logical value `FALSE` to avoid writing the new document.

Value

If the new document is written to a file, the name of the file is returned. Otherwise, the new parsed XML document is returned.
