Getting child elements using WebDriver
提问by FilmiHero
I've got the following HTML code:
我有以下 HTML 代码：
<div class="ui-selectmenu-menu" style="z-index: 1; top: 251px; left: 37px;">
<ul class="ui-widget ui-widget-content ui-selectmenu-menu-dropdown ui-corner-bottom" aria-hidden="true" role="listbox" aria-labelledby="gwt-uid-191-button" id="gwt-uid-191-menu" style="width: 270px; height: auto;" aria-disabled="false" aria-activedescendant="ui-selectmenu-item-999">
<li role="presentation" class="ui-selectmenu-item-selected">
<a href="#nogo" tabindex="-1" role="option" aria-selected="true" id="ui-selectmenu-item-999">All Applications</a></li>
<li role="presentation" class="">
<a href="#nogo" tabindex="-1" role="option" aria-selected="false">Option Alpha</a></li>
<li role="presentation" class="ui-corner-bottom">
<a href="#nogo" tabindex="-1" role="option" aria-selected="false">Option Beta</a></li>
</ul>
</div>
...
<div class="ui-selectmenu-menu"...>...</div>
I'm able to get the WebElement for ui-selectmenu-menulike this (there are many on the page; hence, the use of findElements) :
我能够ui-selectmenu-menu像这样获得 WebElement （页面上有很多；因此，使用findElements）：
List<WebElement> dropdowns = driver.findElements(By.className("ui-selectmenu-menu"));
And the ulbelow it like this:
而ul它下面这样：
WebElement ddChild = dropdowns.get(0).findElement(By.className("ui-selectmenu-menu-dropdown"));
I'm even able to grab all the liunder the ddChildlike this:
我什至可以像这样抓住所有li的ddChild东西：
List<WebElement> ddOpts = ddChild.findElements(By.xpath("//*[@id='gwt-uid-191-menu']/li[*]"));
But the problem that I can't seem to figure out how to grab the text-value of the <a href="#nogo"...tag under each lielement.
但是我似乎无法弄清楚如何获取<a href="#nogo"...每个li元素下标签的文本值的问题。
I'd like to be able to loop through all the ddOptsand grab the <a href="#nogo"...text values and save them to an ArrayList<String>.
我希望能够遍历所有ddOpts并获取<a href="#nogo"...文本值并将它们保存到ArrayList<String>.
So, for example, my first ArrayList<String>value would contain All Applications, then Option Alpha, then Option Beta, and then jump to the next ulelement from the next dropdownsand do the whole process again, all while adding to the ArrayList<String>.
因此，例如，我的第一个ArrayList<String>值将包含All Applications、 then Option Alpha、 then Option Beta，然后ul从下一个元素跳转到下一个元素dropdowns并再次执行整个过程，同时添加到ArrayList<String>.
I'm sure its a simple solution but I've got limited experience with Selenium WebDriver.
我确定这是一个简单的解决方案，但我对 Selenium WebDriver 的经验有限。
Thanks!
谢谢！
PS: Is there a simple way to grab the child of a WebElement?

List<WebElement> ddOpts = ddChild.findElements(By.xpath("//*[@id='gwt-uid-191-menu']/li/a"));
ArrayList<String> links = new ArrayList<String>();
for(WebElement we : ddOpts) {
links.add(we.getText();
}

To extract the hrefattribute of the WebElement(referring to the anchor tag <a>in this example, do this:
要提取(参考本示例中的锚标记)的href属性，请执行以下操作：WebElement<a>
List<WebElement> ddOpts = ddChild.findElements(By.xpath("//*[@id='gwt-uid-191-menu']/li/a"));
ArrayList<String> links = new ArrayList<String>();
for(WebElement we : ddOpts) {
// ADD all the href attribute strings to the list
links.add(we.getAttribute("href"));
}

This may also solve your problem:
这也可以解决您的问题：
List<WebElement> dropdowns = driver.findElements(By.className("x-combo-list"));
WebElement ddChild = dropdowns.get(0).findElement(By.className("x-combo-list-inner"));
List<WebElement> ddOpts = ddChild.findElements(By.xpath("//*[@id=\"x-auto-98\"]/div[4]"));
for(WebElement we:ddOpts){
System.out.println(we.getText());
if(we.getText().contains("ROLE_MANAGER")){
we.sendKeys("ROLE_MANAGER");
we.click();
break;
}
}

the below code will select the OptionAlpha in the dropdown of the above HTML code
下面的代码将在上面的 HTML 代码的下拉列表中选择 OptionAlpha
driver.findElement(By.xpath("//*[@class='ui-selectmenu-menu')).click();
driver.findElement(By.xpath("///*[@class='ui-selectmenu-menu')).click();
driver.findElement(By.xpath("//*[@class='ui-widget ui-widget-content ui-selectmenu-menu-dropdown ui-corner-bottom']//**[text()='Option Alpha']")).click();
driver.findElement(By.xpath("//*[@class='ui-widget ui-widget-content ui-selectmenu-menu-dropdown ui-corner-bottom']//**[text()='Option Alpha']")).click();

Please try the below code to get all the links in the <a href
请尝试以下代码以获取所有链接 <a href
List<WebElement> allLis = driver.findElements(By.xpath("//*[@id='gwt-uid-191-menu']/li/a");
// Looping through above list using for-each loop
for(WebElement eachLi : allLis) {
System.out.println(eachLi.getText());
}
Hope this helps.
希望这可以帮助。

href="#nogo"is same for all the anchor tags, so it might create ambiguity in selecting the item by the method
href="#nogo"对于所有的锚标签都是一样的，所以它可能会在通过方法选择项目时产生歧义
dropdowns.findelement(By.linktext("#nogo"));
