The algorithm <a class="link" href="regex_replace.html" title="regex_replace"><code class="computeroutput"><span class="identifier">regex_replace</span></code></a> searches through a
|
|
string finding all the matches to the regular expression: for each match
|
|
it then calls <a class="link" href="match_results.html#boost_regex.match_results_format"><code class="computeroutput"><span class="identifier">match_results</span><span class="special"><>::</span><span class="identifier">format</span></code></a> to format the string and
|
|
sends the result to the output iterator. Sections of text that do not match
|
|
are copied to the output unchanged only if the <span class="emphasis"><em>flags</em></span>
|
|
parameter does not have the flag <code class="computeroutput"><span class="identifier">format_no_copy</span></code>
|
|
set. If the flag <code class="computeroutput"><span class="identifier">format_first_only</span></code>
|
|
is set then only the first occurrence is replaced rather than all occurrences.
