Cause: < is assumed to be the start tag for build.xml file i.e. in the above example <build is assumed to be the start tag and it complains about the missing closing tag >
Solution: Replace <s; with b i.e. word boundries. Start boundary \< can be replaced with \b and end boundry \> can be replaced with \b in the regular expression.
