I'm try to extract a information from Webpage using the transformer HTMLExtractor, but i didn't a good result.
The Website is http://www.brasil.gov.br/ and the important information for me to extract is the href from this part of page:

Attached my template file.
Thanks in Advance,
Danilo de Lima

I sneaked a peek at the HTML source of the web page. There was no table tag, I think it's the reason why the error occurred.
You can get the HTML doc with the HTTPCaller and then parse the doc to extract the desired element. The HTMLExtractor might help you.
+41HI @danilo_inovacao
Have you tried the HTMLTable reader?
My customer will not use the Reader. For begin the Workspace he 'll use the transformer Creator.
Thanks in Advance,

+43As far as I know, the HTMLExtractor won't read directly from a web site. The HTML has to come from a file, an attribute, or manually entered content. The Help doc suggests that and the error I get seems to confirm it:
'"%s" looks like a URL. Beautiful Soup is not an HTTP client. You should probably use an HTTP client to get the document behind the URL, and feed that document to Beautiful Soup.' % markup)
So your template will not work for sure. Instead add a HTTPCaller first and save the content to an attribute. But like @takashi says, I don't know if you'll get anything because the web page doesn't seem to want to return it. Maybe try a scraping tool to see if it's actually possible to get some data? Otherwise it seems unlikely FME will be able to do anything.
