Hi,
You might want to take a look at TagSoup
(http://community.haskell.org/~ndm/tagsoup) - it parses XML/HTML
lazily returning a stream of tags. It doesn't do nesting, but it does
have good memory usage.
Thanks, Neil

Dear all,
I have been looking at using XML for a little program I have been writing. The file I am currently trying to load is about 9MB, and I have now tried to use HaXml and HST. Without any of my own code, just a simple call to the basic parsers, they both use huge amount of memory. HST is the worst and about 7GB and climbing. HaXml uses 1.3Gb.
The code I am using is HST xml <- readFile file_name_here;k<-runX (parseXmlDocument True) xml;print k
and for HaXml x<-readFile file_name_here let (Document _ _ e _) = xmlParse "t" x let t = myFilter $ CElem e print $ length t
I have seen on previous posts to the cafe that other people have run into this problem with HST. Is this a general problem with XML in Haskell (I know that XML parsing is a slow and bulky process but this seems excessive)? Is there a known solution? Does anyone have any advice?
Cheers
