Phantomjs 单击不带ID的链接或带有casperJS的类

我正在尝试获取此页面左侧菜单上的链接列表：

我要做的第一件事是点击“全部展开”链接（在左上角），这样列表就会展开

我尝试了多种方法以不同的方式使用Xpath，但在此页面上没有成功，这是我最后一次尝试：

casper.start('http://www.hpenterprisesecurity.com/vulncat', function() {
    casper.wait(5000);
    this.echo("---------- TITLE: ");
    this.echo(this.getTitle());

});    

casper.thenClick(x('//*[@id="theContentCenter"]/div/p/a[1]/strong[contains(text(),"Expand")]'),function(){
        casper.wait(5000,function(){
        casper.capture("expanded.png");
        });
    });

也许因为页面缺少大多数元素的ID和标签，我的方法就不起作用了

谢谢

设置：

casper = require('casper').create({
    verbose:true,
    logLevel:"debug"
});


casper.userAgent('Mozilla/5.0 (iPad; U; CPU OS 3_2_1 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Mobile/7B405');
casper.viewport = {width: 1280, height: 720};

var x = require('casper').selectXPath;
