xml_find doens't see added attributes with namespaces #340
Description
Activity
Looks like this works if you manually specify the namespace when setting the attribute; I suspect
xml_add_childisn't correctly passing the ns info around.library(xml2) doc <- read_xml('<?xml version="1.0" encoding="UTF-8"?><bookstore xmlns:xxx="https://www.w3.org/"><book name="Harry Potter 1"></book></bookstore>') xml_ns(doc) #> xxx <-> https://www.w3.org/ node <- xml_find_first(doc, "book") link <- xml_add_child(node, .value = "link") xml_set_attr(link, "xxx:resource", "http://harry_potter.com", ns = xml_ns(doc)) xml_find_all(doc, "//link[@xxx:resource=\"http://harry_potter.com\"]") #> {xml_nodeset (1)} #> [1] <link xxx:resource="http://harry_potter.com"/>

I'm trying to modify xml by adding child nodes with attributes, and then I'm looking for the subset of added nodes with attributes I just added:
The bug is related to namespaces. If the added child node and query doesn't have xxx: namespace, the output is correct, and results 1 contain the node that was added.
