Product.......: R:BASE X.5 and R:BASE X.5 Enterprise (Version 10.5)
Build.........: 10.5.2.11111 or higher

Keywords......: Web Browser, PROPERTY, GETPROPERTY, TAG, ID, NAME
Did you know the Web Browser controls have been enhanced to allow manipulation
of HTML controls in EEPs?
The Web Browser controls support dynamic properties to allow manipulation of
HTML controls in EEPs with the PROPERTY and GETPROPERTY commands. The dynamic
properties are useful in the following:
. Integrating local data with web sites that do not have an API
. Automating web page tasks within R:BASE
. Extracting data from web pages
Dynamic Properties
------------------
HTML elements can be referenced by TAG, ID, and NAME. For a well defined HTML
page, the ID alone is enough to locate the HTML element. In case of conflicts
combination of the three identifiers can be used depending on the document.
The property name is preceded with an underscore to distinguish
between dynamic
and non-dynamic properties. Dynamic property is composed of the property name
and the HTML element identifiers.
The full dynamic property name syntax is: "_PROP|TAG xxx|ID yyy|NAME zzz"
Parameters:
_CLICK - simulates a mouse click on a control on the page (e.g. button, link)
PROPERTY WebBrowser1 "_CLICK|ID btnSubmit" "AnyValue"

stripping all the tags
