While using WebUI.Get Text () method to retrieve a large amount of text from the body of a html page, it was not parsing the full amount of text into a variable. The variable seemed to be storing only the half amount of text if not less. Anything above 100 characters of the text was not stored in the variable. My work around was to use the get text () method and then write it to a local file. This worked.
