Greetings. I am trying to move some very old code from using HaXml to HXT. This is experimental; I have reasons which I think are not relevant to this post.

The website that purports to document HXT has broken links. This is Uwe Schmidt's website. I have emailed Dr. Schmidt. Meanwhile, can anyone elucidate the use of readDocument with its withCurl and withHTTP options? What may be passed in the list to e.g. withHTTP?

Why don't you use the documentation on Hackage? Here[1] is your

readDocument. It mentions the withCurl option and how to use it. As it points out, the withCurl comes from hxt-curl and the relevant page is at [2]. As you can see, it takes Attributes which is just a list of

Yes. The "relevant page is at [2]". Clicking on that link takes me to a page that tells me this: withCurl :: Attributes -> SysConfig So now I want to know what about "Attributes" (above). If I click on the link to "Attributes" in the hackage documentation I discover this: Attribute list used for storing option lists and features of DTD parts So, I am clearly missing something - which, as usual, is probably my fault. What I am missing is: what goes in the attribute list for e.g. withCurl?

Thanks, Michael. I can get withCurl to work when I supple an empty list, but I am guessing that the curl options allow more control. There is a link that purports to document curl and http options, but the links are broken. I contacted Uwe Schmidt (a prof who spearheaded development of HXT, I think). He replied to say that he would check into it when he has time. I may have to plunge into the source code to see how curl and/or http actually get called if nobody restores the broken links. Meanwhile thanks for the reply. - P -

Ah, beauty, thanks. I should have thought of that. Muchas Gracias. - P - On 2014-02-21, at 12:43 AM, Vlatko Basic wrote:

Hi Philippe,

Have you taken a look at [1]

That's what actually gets called from [2]
