Node attributes printed on close tag

[gregmacfarlane]

If I add an attribute to a tag, then the attribute is also printed when the tag is closed.

script <- xml2::xml_new_document() %>%
  xml2::xml_add_child("osm-script")
union <- xml2::xml_add_child(script, 'union into="_"')
query <- xml2::xml_add_child(union, 'query type="way"')
script
## {xml_document}
## <osm-script>
## [1] <union into="_">\n  <query type="way"/>\n</union into="_">

This seems to violate xml syntax, e.g. in the wikipedia example

<step number="3">Connect A to B.</step>

Am I mistaken? Is there a way to turn off this behavior?

Your single quotes seem to be in the wrong place, which is causing the 'attributes' to be treated as text nodes.

script <- xml2::xml_new_document() %>%
  xml2::xml_add_child("osm-script")
union <- xml2::xml_add_child(script, "union", into = "_")
query <- xml2::xml_add_child(union, "query", type = "way")
script
#> {xml_document}
#> <osm-script>
#> [1] <union into="_">\n  <query type="way"/>\n</union>

Ah, I've got it. So the tag name and the attributes should come separately. Too clever for me to see immediately, but I've got it now.
