Unable to get nokogiri xmlelement text value - ruby

Question

I have the following XML content.
<info>
<meta name="alias">alias1</meta>
<meta name="score">.60</meta>
</info>
<info>
<meta name="alias">alias2</meta>
<meta name="score">.50</meta>
</info>
I need to get back for each value, but having difficulty doing so.
doc.xpath("//info").each do |info_entry|
info_entry.xpath("meta").each do |meta_entry|
if meta_entry['name'] == 'alias'
the_alias = meta_entry.xpath('text()').text
elsif meta_entry['name'] == 'score'
score = meta_entry.xpath('text()').text
end
// add struct containing alias and score to list
end
end
However, I'm not geting anything from text. I've tried many different things: inner_text, inner_html, content, value, nothing works. I've tried meta_entry.at, meta_entry.search, and so on.
Is there something I'm missing? Any advice would be appreciated.

You need to get rid of xpath('text()'). And you can get rid of the conditional and build a workable data structure as you go, like this:
def meta_contents(doc)
doc.xpath("//info").map do |info_entry|
info_entry.xpath("meta").map do |meta_entry|
[meta_entry["name"], meta_entry.text]
end.to_h
end
end
>> meta_contents(doc)
#> [{"alias"=>"alias1", "score"=>".60"}, {"alias"=>"alias2", "score"=>".50"}]
