Hi,
I've been having some (apparently) odd behavior with regular
expressions. Can anyone please tell me if the following program should
work as I am seeing?
---
import org.apache.xerces.impl.xpath.regex.RegularExpression;;
public class ReTest {
public static void main(String[] args) {
String s = "Another test";
String p1 = "foo";
String p2 = "foo.*test";
RegularExpression re = new RegularExpression(p1);
print(s, p1, re.matches(s));
re.setPattern(p2);
print(s, p2, re.matches(s));
re = new RegularExpression(p2);
print(s, p2, re.matches(s));
}
static void print(String str, String pattern, boolean match) {
System.out.print("Pattern '" + pattern);
if (match) System.out.print("' matches '");
else System.out.print("' does not match '");
System.out.println(str + "'");
}
}
---
The output I expect to see is:
Pattern 'foo' does not match 'Another test'
Pattern 'foo.*test' does not match 'Another test'
Pattern 'foo.*test' does not match 'Another test'
The output I actually see is:
Pattern 'foo' does not match 'Another test'
Pattern 'foo.*test' matches 'Another test'
Pattern 'foo.*test' does not match 'Another test'
In other words, setPattern() is not working the way I expect it to. Is
this right?
Thanks in advance,
Paul Gearon
