如何在java中写下xpath

Question

//div[@ng-if="subNav.state == 'active'"]

我尝试如下，但得到＆＃34; InvalidSelectorException＆＃34; ：

String active = "subNav.state == 'active'";
driver.findElement(By.xpath("//div[@ng-if='"+active+"']"))

＆＃13;

＆＃13;

<li class="active" on="subNav.state != '' && subNav.state != 'active'" ng-switch="" ng-repeat="subNav in navigation[activeNav].pages | filter:subNavFilter(navigation[activeNav].pages)">
	<div class="whereabouts ng-scope" ng-if="subNav.state == 'active'"></div>
	<span class="badge badge-active" aria-disabled="true" ng-if="subNav.state != 'complete'">6</span>
	<span class="ng-binding ng-scope" ng-switch-when="false">Loan</span>
</li>

＆＃13;

＆＃13;

Answer 1

如果在值中使用了引号，你应该转义引号。我建议用双引号来关闭所有引号。 这是xpath

    String active = "subNav.state == 'active'";
    driver.findElement(By.xpath("//div[@ng-if=\"" + active + "\"]"));
