Extracting values from text using patterns

Some methods in GrabzIt's Web Scraper such as the Page.getValue method allows data to be extracted from text by specifying a pattern, which defines how to capture the desired part of the returned text. The the value to capture is indicated by the {{VALUE}} in the pattern. For example to capture the age from 'My age is 33.' the pattern 'My age is {{VALUE}}.' would be used.

Page.getTagValue({"tag":{"equals":"p"}}, 'My age is {{VALUE}}.');
