20px-Function.png grep(<object>,<attrs>,<pattern>)

This function returns a list of attributes on <object> containing <pattern>. <attrs> is a wildcard pattern for attribute names to search; if you want to search all attributes, use "*".

Parsing _does_ occur before this function is invoked. Therefore, "special" characters will need to be escaped out. <pattern> is NOT wildcard matched.

This function is case-sensitive. grepi() is a case-insensitive version.
