How do I select child elements of any depth using XPath

Question

Suppose I have this  simplified     lt form id  myform  gt       lt  -- some input fields -- gt       lt input type  submit  value  proceed   gt   lt  form gt    Then I can select the submit button by XPath   form  id  myform   input  type  submit    Great   However  my templates might change and I want to be flexible in the depth in which the submit button is located  It might be put in a table  like this    lt form id  myform  gt       lt  -- some input fields -- gt       lt table gt  lt tr gt  lt td gt              lt input type  submit  value  proceed   gt       lt  td gt  lt  tr gt  lt  table gt   lt  form gt    I know I can select elements which are grandchildren  but I can t select grand-grand-grand-   -childeren of any depth  E g       form  id  myform     input  type  submit   only selects grand-children  no further depths    form  id  myform       input  type  submit   only selects grand-grand-children  no further or less depths    form  id  myform      input  type  submit   is not valid    So  how do I select this submit button reliably without using element IDs
