I think HXT, a XML/HTML processing library in Haskell, has really flexible and powerful methods for traversing and manipulating DOM trees by Arrows. http://adit.io/posts/2012-04-14-working_with_HTML_in_haskell.html
It seems, however, HXT has only String representation for DOM node contents. http://hackage.haskell.org/packages/archive/hxt/9.1.6/doc/html/Text-XML-HXT-DOM-TypeDefs.html#t:XNode
Is it possible to use either of ByteString or Text for HXT? Text is preferred since I am using HXT with Yesod, which seems to mainly use Text.
回答1:
Neither HXT nor HaXml appear to support either bytestring or text, but if you are working with Yesod you should probably use xml-conduit and html-conduit anyway.
