How do I extract inner text from HTML markup?

I have the following code:

import Text.HTML.TagSoup

parseTags "<hello>my&amp;</world>"

which is giving me output like: [TagOpen "hello" [],TagText "my&",TagClose "world"]. But I want to get only [TagText "my&"]. And I can do this:

filter (~== "my&")$ parseTags "<hello>my&amp;</world>"

which will give me output like: [TagText "my&"]. But I do not know what is inside the TagText, i.e. "my&". My ultimate target is to get "my&" which I can get by

map(fromTagText) $ filter (~== "my&")$ parseTags "<hello>my&amp;</world>"

I tried to use TagText, but can’t do it right way.

If you really only want the "my&" you can use innerText from TagSoup:

innerText (parseTags "<hello>my&amp;</world>")

It only looks for text tags and concatenates them. So this

innerText (parseTags "<hello>my&amp;</world><foo>bar</foo>")

gets you "my&bar".
