regex_replace

Applies a regular expression operation on the input. This filter accepts two input values: one is the pattern, the second is the replacement.

Example:

    <$mt:EntryTitle regex_replace="/\s*\[.+?\]\s*$/",""$>

This would strip any bracketed phrase from the end of the entry title field.

Note that the "g" global modifier is valid here, which will find all occurrences, not just one. Extending the above example:

<$mt:EntryTitle regex_replace="/\s*\[.+?\]\s*$/g",""$>

List entry categories if their label is within the set Explore, Savor, Inside, Offbeat, or Celebrate and then glue them with ", ". (The regex_replace modifiers remove extra glue from beginning, end, and between categories that don't match the if statement)

<mt:EntryCategories glue=", " regex_replace="/(,\s+)+/":", " regex_replace="/,\s+$/":"" regex_replace="/^\s+,\s+/":"">
    <mt:If tag="CategoryLabel" like="(Explore|Savor|Inside|Offbeat|Celebrate)">
        <a href="<$mt:CategoryArchiveLink$>"><$mt:CategoryLabel$></a>
    </mt:If>
</mt:EntryCategories>

This is only here as an example, a much better solution would be to use mt:SevVarBlock with function="push" attribute and then output with mt:Loop
