I have this XPath works with xmllint

//td[text() = 'USD']/../td[6]/text()

Now I want it to be done in Haskell. But following (not complete of the original XPath) does not work at all. I got empty list error on head.

cur $// element "td" &// check (\c → "USD" ≡ head (c $// content))

What happens if you replace `head` with `mconcat` to get _all_ of the descendant text nodes instead of just the first one? You may also need to consider using `strip` to get rid of whitespace. – Michael Snoyman Aug 01 '18 at 04:41
@MichaelSnoyman Ah, I see. Thanks. – Magicloud Aug 01 '18 at 13:43
