google news reader

[vamzicool]

This single flow reads the google RSS feed and retrieves the news headlines and reads it out aloud.it uses the split function to do the dirty work.I tried using regular expression but it gave me only one single news headline. I'll be grateful if someone could help me with the regular expression part.

Thanks

Hi,

You could use XPath to extract the titles from an RSS feed. XPath is quite limited in Automagic, but might work better than regular expressions in this case since there are multiple different elements containing a title element.

Code: Select all

headlines=newList();
count=evaluateXPathAsString(response, "count(//item)");
for (i in [1 to count])
{
  title=evaluateXPathAsString(response, "//item[{i}]/title");
  addElement(headlines, title);
}

The first XPath expression counts the number of item elements. The second XPath expression extracts the n-th title (within an item) and adds the title to a list.

Regards,
Martin

Thanks a lot Martin, xpath works like a charm. I didn't know about this. Now I think its worth that I switched from tasker to automagic.
