I'm trying to match a specific string out of a an HTML document and have this regex pattern to grab it:

Pattern somePattern = Pattern.compile("var json = ({\"r\":\"^d1\".*});");

However when I try to hit that code at runtime, I get this error:

FATAL EXCEPTION: Timer-0
 java.util.regex.PatternSyntaxException: Syntax error U_REGEX_RULE_SYNTAX near index 13:
 var json = ({"r":"^d1".*});
              ^

     at java.util.regex.Pattern.<init>(Pattern.java:341)
     at java.util.regex.Pattern.compile(Pattern.java:317)

Can anybody tell me what I'm doing wrong?
