Web automation

I have a linkedin group with quite a few members. Linkedin allows me to send members messages on indivdual basis. I would like to automate the process. The script should: 1. Identify position of the first "send message" string on the page (see attached files) 2. Copy the "First name" of the member on the same line of the identified "send message" text string 3. Click "send message" on the same line 4. Paste standard message in "Subject" field 5. Paste "standard message on the body, including the previously copied "First name" 6. Click "Send message" 7. Try to identify next "send message" string on the page - if available go to point 2 - if not available go to 8 8. Click "next" at the end of the page 9. Goback to 1 10 If no "next" button is active then the job is completed A log file should be generated and updated throughout the process
