It may be a quirk of how Pharo Playground works. It doesn't need local variable declarations - which is convenient - but putting them in can screw things up. Try your snippet again without the first line. Compare Torsten's code.

Works without a problem (Pharo 8 on Windows), see attached. So it looks like a local problem.

Just check the debugger and compare to the squeak version where you run in trouble.
Maybe the document could not be retrieved on your machine.

Hi,


You can load using

  Metacello new

repository: 'github://pharo-contributions/XML-XMLParserHTML/src';
load.

Hi,

I'm trying to use the sample code in the pharo screen scraping booklet
���
http://books.pharo.org/booklet-Scraping/pdf/2018-09-02-scrapingbook.pdf ��� but while everything appears to load, I'm getting an odd behavior from:

/| ingredientsXML |
ingredientsXML := XMLHTMLParser parseURL:
'https://ndb.nal.usda.gov/ndb/search/list?sort=ndb&ds=Standard+Reference'.
ingredientsXML inspect/

"#new was sent to nil"

No matter what URL I use, I get the same message.

I'm using Mac OS Catalina so I thought I might have some strange Mac
OS security issue (like it was quietly refusing to allow Pharo to
access the internet), but I tested with squeak and the old

/html :=(HtmlParser parse:
'https://ndb.nal.usda.gov/ndb/search/list?sort=ndb&ds=Standard+Reference'
asUrl retrieveContents content)/

and that returns actual html without any problems.


Suggestions?


Thanks.

L
