I've created a feed attached to a story, and selected HTML, and specified my feed URL as http://www.theregister.co.uk/ and the context is: /html/body/div[2]/div[6] On clicking preview, I get the error message:

warning: Invalid argument supplied for foreach() in /public_html/sites/all/modules/feeds_xpathparser/FeedsXPathParserHTML.inc on line 54.

If I change the context from /html/body/div[2]/div[6] to /html/body/div[2], then I no longer get the warning message.

I'm getting the XPath using Firebug (useful!). I also get the message "Could not retrieve title from feed.", but I guess that's my incompetence at working out the correct XPath for the story titles.

I tried both queries on el reg and neither of them turned up anything. Try the XPath and XPather firefox extensions. They should be a big help. The no title issues is that you're not setting a title for the feed node itself. I've got it in the works to parse out the title for it when using only the HTML parser, but that'll be a few days.

Here are the links to the Firefox add-ons, which look useful:

  • XPather "Feature rich XPath generator, editor, inspector and simple extraction tool"
  • XPath Checker "An interactive editor for XPath expressions"

And some extra ones:

  • FireXPath "a Firebug extension that adds a development tool to edit, inspect and generate XPath expressions."
  • Firefinder for Firebug "A Firebug add-on that finds HTML elements matching chosen CSS selector(s) or XPath expression"

If and when you start a Drupal documentation page for your Feeds XPath Parser, this kind of information can go there.

The message "Could not retrieve title from feed" is actually because you didn't set the title of the feed node. I have to make that feed mandatory. Are you still having trouble?

@myregistration,

What version are you using? Example XML/HTML and XPath queries? I need the information necessary to reproduce your error.
