regex that matches URL to image than replaces characters -


hi long time reader first time poster regex question

i have rewrite rules in xml file this notation

<rule> <from></from> <forward></forward> </rule>

in node, looking match url has image extension @ end , dash "-" characters in name. if matches, in forward node replace dash "-" characters underscore characters "_"

for example

you can try on top of .htaccess

rewriterule ^(.*)(\-|%2d)(.*)$ /$1_$3
