Question

This regular expression in C# is giving me error in java:

"<input type="hidden" name="GALX" value="(?<galx>[a-zA-Z0-9_]+)">"  

Error:

Look-behind group does not have an obvious maximum length near index 60
<input type="hidden" name="GALX" value="(?<galx>[a-zA-Z0-9_]+)">

What would be the equivalent expression in Java?

Answer 1

This i’m guessing. I changed ‘ to ” and escaped any “

"<input type=\"hidden\" name=\"GALX\" value=\"(?<galx>[a-zA-Z0-9_]+)\">" 

Edit :: And for the named grouping of “galx” only java 7 supports this
