如何将变量传递给XPathExpression

Question

我想在XPathExpression中传递变量的值.我想将id值放在变量中.我怎样才能做到这一点？以下是代码;

XPathExpression expr = xpath.compile("//Number[@id=1]/Movies/text()");

上面,我想把id的值放在一个变量中.我尝试了int num = 1但是没有用.谢谢.

String yourArg= "1";
XPathExpression expr = xpath.compile("//Number[@id="+yourArg+"]/Movies/text()");
