Re: [Pharo-project] Newbie: How to load and use HTTP parser

May 10, 2010

      When I try to execute
( HtmlValidator onUrl: 'http://en.wikipedia.org/wiki/Pharo' asUrl ) dom.

I get an error:
ByteString(Object)>>doesNotUnderstand: #url
HtmlValidator>>document
HtmlValidator>>content
HtmlValidator>>parse
HtmlValidator>>dom
UndefinedObject>>DoIt
Compiler>>evaluate:in:to:notifying:ifFail:logged:
[] in TextMorphForShoutEditor(ParagraphEditor)>>evaluateSelection
BlockClosure>>on:do:
TextMorphForShoutEditor(ParagraphEditor)>>evaluateSelection
TextMorphForShoutEditor(ParagraphEditor)>>doIt
[] in TextMorphForShoutEditor(ParagraphEditor)>>doIt:
TextMorphForShoutEditor(ParagraphEditor)>>terminateAndInitializeAround:
TextMorphForShoutEditor(ParagraphEditor)>>doIt:

TextMorphForShoutEditor(ParagraphEditor)>>keystroke:
TextMorphForShoutEditor(TextMorphEditor)>>keystroke:
[] in [] in TextMorphForShout(TextMorph)>>keyStroke:
TextMorphForShout(TextMorph)>>handleInteraction:

The failing place is:
document
    "Answer the value of document"

    document isNil ifTrue:
    [
        url isNil
            ifTrue: [nil]
            ifFalse:
            [
                document := self loader documentForUrl: self url.
                loader url: document url.
            ]
    ].
    ^document

Looks like "document url" trips on url.

I am new to ST, how can I find what's missing?
Thank you,
Andrew

Hi
Sent this message to the Pharo-users group, but no response for a couple
of
days, so trying it here ;)
I have a simple task of parsing some html content in Pharo (loading an
html
page using HTTPSocket and retrieving useful info from it).
Having browsed for an html parser in my current one-click Pharo 1.0
image, I
couldn't find one.
How do I find/download a (the) HTML parser?
What's the general routine of discovering and installing packages in
Pharo?
I believe in Squeak there was a menu to explore and download packages, I
couldn't find it in Pharo though.
Thank you,
Andrei
