How can I separate the lines of code surrounded by the <plaintext> tags from everything else? And is it possible to erase the <plaintext>&</plaintext> tags to keep just the answer?

Would string.match work? Or string.gmatch if you want all of the <plaintext>s.


local document = 'that XML stuff you have there'
local texts = {}

for content in document:gmatch "<plaintext>(.+)</plaintext>" do
  table.insert(texts, content)
end

Basically throws the content of all of the plaintext tags into the "texts" table.</code>

</div></plaintext></code>

</div></plaintext>

Almost worked, the thing that happens is: It looks from the first <plaintext> to the last </plaintext>, instead of looking from <plaintext> to the next </plaintext>

Oops.

Change "(.+)" to "(.-)".
