Hello,
I'd like to pinpoint the place in an HTML document where the <body .....>
tag closes.
My first try, the regular expression
<html([\n\r\f]|.)*<body[^>]*(>)
compiles but takes forever to match (and I actually mean forever...). Then I
guessed that maybe a reluctant closure would provide the desired solution
and I rewrote it to:
<html([\n\r\f]|.)*?<body[^>]*?(>)
The RECompiler however, crashes with an ArrayIndexOutOfBoundsException
(stacktrace see below)
Does anyone have an idea?
Ciao
Sven

My method, setLocation, does nothing but.
public void setLocation (String location) {
try {
this.location = new RE (location);
} catch (RESyntaxException e) {
logger.error ("SyntaxException occured while parsing location String");
return;
}
this.originalLocation = location;
}
