Details

This function returns XML nodes as used in openxlsx2. In theory they could be returned as pointers as well, but this has not yet been implemented. If no level is provided, the nodes on level1 are returned

Examples

  x <- read_xml("<a><b/></a>")
  # return a
  xml_node(x, "a")
  # return b. requires the path to the node
  xml_node(x, "a", "b")
  xml_node_name("<a/>")
  xml_node_name("<a><b/></a>", "a")
  x <- read_xml("<a>1</a>")
  xml_value(x, "a")

  x <- read_xml("<a><b r=\"1\">2</b></a>")
  xml_value(x, "a", "b")

  x <- read_xml("<a a=\"1\" b=\"2\">1</a>")
  xml_attr(x, "a")

  x <- read_xml("<a><b r=\"1\">2</b></a>")
  xml_attr(x, "a", "b")
  x <- read_xml("<a a=\"1\" b=\"2\">1</a>")
  xml_attr(x, "a")

  x <- read_xml("<b><a a=\"1\" b=\"2\"/></b>")
  xml_attr(x, "b", "a")
