  Sample input:
xExtractHtmLContent ( Searches::za2Url; "q="; & Searches::xa2Address4GoogleMap ; Searches::zb5Width ; Searches::zb5Height; Searches::zb5WidthOffset ; Searches::zb5HeightOffset ; 1 ; 1 )
  Sample output:
[html string]

  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Enables offsets to be used to hide elements in the source screen that you don't want to be viewed in the FileMaker Web Viewer - this is an amazingly useful function enabling you to precisely control what information - for example from a mapping site - you choose to display.
This updated version also resizes the source content as the web viewer is resized as the Filemaker Window is resized.

Discovered a very interesting affect of this. If you have a negative offset, then clicking in the webviewer window produces a click in the associated region of the Filemaker layout.

So by scrolling in a web viewer, I select and scroll text in a field that is above and to the left of the web viewer. Very weird.

I pasted the text above into a new custom function and when I click OK I get the following error: "The specified parameter can not be found" with "address" highlighted. Is "address" supposed to be another input parameter?

This CF seems to have typos in parameters and a number of missing parameters as well. Too bad because this would be quite useful.
