How to extract data from html table in shell script?

Answer 1

You may use html2text command and format the columns via column, e.g.:

$ html2text table.html | column -ts'|'

Component                                      Status  Time / Error
SAVE_DOCUMENT                                           OK            0.406 s     
GET_DOCUMENT                                            OK            0.332 s     
DVK_SEND                                                OK            0.001 s     
DVK_RECEIVE                                             OK            0.001 s     
GET_USER_INFO                                           OK            0.143 s     
NOTIFICATIONS                                           OK            0.001 s     
ERROR_LOG                                               OK            0.001 s     
SUMMARY_STATUS                                          OK            0.888 s     

then parse it further from there (e.g. cut, awk, ex).

In case you'd like to sort it first, you can use ex, see the example here or here.
