I have been building a program recently that makes accessing information easier, mostly for definitions to words for school. It works effectively so far, it searches a first site for a word entered into the textbox, and if a 404 error is recieved, it navigates to the next site and serches for the word. however, i would like that if the definition is found on the first sit (e.g. no 404 error is recieved) than when i hit a button (btnCopy) it will copy from point A which is the word "Definitions:" (yes, the colon was on purpose) to point B the word "Synonyms:". This copy will hopefully not include Point A or Point B, nor require any prior knowledge of what will be found between the two points.
EDIT: all copying is intended to go on within the "Webbrowser" tool
