replace_tag tagname expression

Assign a valid regular expression to tagname.

Note: It is not recommended to put quantifiers inside the tag, it's better to put them inside the rule itself for greater flexibility.

replace_pre tagname expression

Assign a valid regular expression to tagname. The expression will be placed before each tag that is replaced.

replace_inter tagname expression

Assign a valid regular expression to tagname. The expression will be placed between each two immediately adjacent tags that are replaced.

replace_post tagname expression

Assign a valid regular expression to tagname. The expression will be placed after each tag that is replaced.

replace_rules list_of_tests

Specify a list of symbolic test names (separated by whitespace) of tests which should be modified using replacement tags. Only simple regular expression body, header, uri, full, rawbody tests are supported.

replace_start string

replace_end string

String(s) which indicate the start and end of a tag inside a rule. Only tags enclosed by the start and end strings are found and replaced.
