Get text of webpage

This is helpful, but when I try to put it into a message it doesn't show it all, only the first set of numbers.

I just tested it with this but I dont get everything.

Please read QM help about the from function.

I didnt realize I had message.from I thought I had message.formata. That fixed almost everything. This will work like this, but one last question. Is there any way to seperate them like you had them seperated in the example? Or maybe spaces? It's just a little clustered around the dates.

function $HTML VARIANT'tableNameOrIndex [ARRAY(str)&a] [ARRAY(MSHTML.IHTMLElement)&a2] [flags] [str&tableText] ;;flags: 1 get HTML, 2 get all TD elements, including of inner tables

;Gets cells of a HTML table into an array.

;HTML - all HTML (page source).
;tableNameOrIndex - table name or 0-based index in the html. The function throws error if the specified table does not exist.
;a - array variable for results. The function creates 1-dimension array where each element is cell text. Can be 0 if not needed.
;a2 - array variable for results. The function creates 1-dimension array where each element is cell object that can be used to get html elements within the cell. Can be 0 if not needed.
;tableText - str variable that receives whole text or html of the table. Can be 0 if not needed.
