matchcollection collections = regex.matches(parameters, "<movement display_name=\"movement\" type=\"(<type> .*?).*? min=\"(<min> .*?) .*? max=\"(<max> .*?)\" />", regexoptions.singleline);  foreach(match match in collections) {      console.writeline(match.groups["type"].value);      console.writeline(match.groups["max"].value); }

as mentioned need capture , replace max value, take account non-capturing group.

the special character \s+ used indicate 1 or more white spaces.

regex reg = new regex("(movement\s+display_name=\"movement\"\s+type=\".*\" .*min=\".*\"\s+max=\").*(\")");

now can replace not captured group, mean "max" value:

reg.replace(texttosearch, "$10.99$2");

what did here keep captured groups , replace not captured value: "$1<replacement>$2". captured groups can accessed via reference $<group>.
