md_ns: Aliased namespace prefix for commonmark

In tinkr: Cast '(R)Markdown' Files to 'XML' and Back Again

Aliased namespace prefix for commonmark

Description

The commonmark package is used to translate markdown to XML, but it does not assign a namespace prefix, which means that xml2 will auto-assign a default prefix of d1.

Usage

md_ns()

Details

This function renames the default prefix to md, so that you can use XPath queries that are slightly more descriptive.

Value

an xml_namespace object (see xml2::xml_ns())

Examples

tink <- tinkr::to_xml(system.file("extdata", "example1.md", package = "tinkr"))
# with default namespace
xml2::xml_find_all(tink$body, 
  ".//d1:link[starts-with(@destination, 'https://ropensci')]"
)
# with tinkr namespace
xml2::xml_find_all(tink$body, 
  ".//md:link[starts-with(@destination, 'https://ropensci')]",
  tinkr::md_ns()
)
