Ok....



I believe this is the problem.



Set a breakpoint In WebClient sendRequest: request contentBlock: contentBlock 



for the simple 

(WebClient httpGet: 'https://w1.weather.gov/xml/current_obs/index.xml') 







the WebRequest object looks like this:



WebRequest(GET /xml/current_obs/index.xml HTTP/1.1



User-Agent: WebClient/1.5 (WebClient-Core-dtl.127; Squeak6.0alpha-20633; unix)



Accept-Encoding: gzip



Host: w1.weather.gov







)





For the 



(XMLDOMParser onURL: 'https://w1.weather.gov/xml/current_obs/index.xml' upToLimit:nil)




the WebRequest looks like this:



WebRequest(GET /xml/current_obs/index.xml HTTP/1.1



Host: w1.weather.gov







)


looking a little deeper, the headers are different...


So...will try to figure out where that is set in one and not the other

Hi --



Not sure, which error your mean. Well, I had this little "contentStream" typo. This is the right call:



(WebClient httpGet: 'https://w1.weather.gov/xml/current_obs/index.xml') content.



Yet, I understand your "interop" concerns.



Best,

Marcel

Hi Marcel.



It throws a Mal Formed Error on Squeak and on Pharo, the dependency on WebClient is not respected.



Thank you for trying, I appreciate the effort.



I am going to look deeper into the original error and see if I can fix it there.



The reason interop is important, is because it makes the Help portable and  I want to turn my work into a Pillar booklet as a first effort towards a full book on using the XML package on Squeak or Pharo.



Thanks again.

Hi --



It would be nice to have a streamlined support for loading XML documents from URLs. I think that WebClient would be the way to go for HTTP downloads:

(WebClient httpGet: 'https://w1.weather.gov/xml/current_obs/index.xml') contentStream



"XML-Parser" currently depends on "Files" because of SAXHandler class >> #parserOnFileNamed:. A dependency on "WebClient" might not hurt ... maybe through the "Tools" package? Hmmm...



Well, I don't like the class-side interface of SAXHandler and XMLDOMParser. Instead, I prefer the reader/writer notion like this:



XMLDOMParser onFileNamed: '...'

XMLDOMParser onURL: '...'



Considering the actual result, I like the interface of Form (for PNGs, JPEGs, etc.):



XMLDocument fromFileNamed: '...'

XMLDocument fromURL: '...'



Please find attached a change set that makes the proposed interface work in Squeak Trunk.



Best,

Marcel

Hi Folks,



No biggie, just interesting...





    |tree url |

    url := 'https://w1.weather.gov/xml/current_obs/index.xml'.

    tree := (XMLDOMParser on:  (HTTPLoader default retrieveContentsFor: url) contents

    ) parseDocument.

    tree explore.



(XMLDOMParser onURL: 'https://w1.weather.gov/xml/current_obs/index.xml') parseDocument; explore.  "throws an error"







The first form works on squeak.

The latter form works on pharo.

The latter does NOT Squeak because the XMLHTTPException: Forbidden (403) error gets thrown.



It is interesting that a platform difference would cause that error.



No biggie, but I would like to include a common retrieval method for both platforms in the XPathHelp (May turn it into a book down the road,too)



cheers.
