Description

Look for elements in <list> that match <pattern>. This command is a decent replacement for TclX lmatch command when TclX is not available

In the following example a regular expression is matched against each element in the input list and a list containing the matching elements is returned

::rivet::lmatch -regexp { aaxa bxxb ccxxxxcc } {.+[x]{2}.+}
bxxb ccxxxxcc
