如何在selenium webdriver中从HTML中获取标记名

Question

我想要在http://www.redbus.in/Booking/SelectBus.aspx?fromCityId=124&fromCityName=Hyderabad&toCityId=462&toCityName=Mumbai&doj=30-May-2013&busType=Any&opId=0中获得所有旅行的名称，出现在标记中(它们是动态的，所以想要在数组中进行计数)

以下是html文件的某些部分

<div id="t1-results">
<table id="t1-list5" class="list5" cellspacing="0" cellpadding="0" style="margin-top:0px;">
 <tbody id="t1-0">
 <tr class="r1">
 <td class="i1">Akbar Travels</td>
 <td class="i2">
 <td class="i3">
 <td class="i4">
 <td class="i5">
 <td class="i6">
 <td class="i7">
  </tr>
 <tr class="r2">
 <tr class="r3">
 </tbody>
 <tbody class="hrblank">
 <tbody id="t1-1" class="G">
 <tr class="r1">
 <td class="i1">Omer Travels</td>
 <td class="i2">
 <td class="i3">
 <td class="i4">
 <td class="i5">
 <td class="i6">
 <td class="i7">
 </tr>
 <tr class="r2">
 <tr class="r3">
 </tbody>
 <tbody class="hrblank">
 <tbody id="t1-2">
 <tr class="r1">
 <td class="i1">Sangita Travel Agency</td>
 <td class="i2">
 <td class="i3">
 <td class="i4">
 <td class="i5">
 <td class="i6">
 <td class="i7">
 </tr>

我已经尝试过

        List<WebElement> linkElements = driver.findElements(By.tagName("//table[@cellspacing=\"0\"]"));

        String[] linkTexts = new String[linkElements.size()];

当我将got作为linkElements ArrayList<E> (id=82)进行调试时

                   `linkTexts         String[0]  (id=95)`

不起作用。

我也试过了

List<WebElement> linkElements = driver.findElements(By.tagName("t1-results"));

        String[] linkTexts = new String[linkElements.size()];

有没有人能建议我怎么取名字。

Answer 1

尝试使用CSS选择器，如下所示：

List<WebElement> linkElements = driver.findElements(By.cssSelector("table tr.r1 > td.i1")); 

我刚刚做了一个快速测试，这段代码找到了所有63个匹配项(在撰写本文时)：

driver.get("http://www.redbus.in/Booking/SelectBus.aspx?fromCityId=124&fromCityName=Hyderabad&toCityId=462&toCityName=Mumbai&doj=30-May-2013&busType=Any&opId=0");

//Find's the elements using a CSS selector: all td's (with class "i1"), directly inside a tr (with class r1) which are inside a table.
List<WebElement> linkElements = driver.findElements(By.cssSelector("table tr.r1 > td.i1"));
String[] linksText = new String[linkElements.size()];
int index = 0;
for(WebElement element : linkElements){
    linksText[index++] = element.getText();
}

Answer 2

Xpath也是一个很好的选择，希望能对你有所帮助。

List<WebElement> linkElements = driver.findElements(By.Xpath("Your Xpath"));
String[] linksText = new String[linkElements.size()];
int index = 0;
for(WebElement element : linkElements){  
linksText[index++] = element.getText();
}

Answer 3

尝试使用下面给出的CSS计数概念

int size=driver.findElements(By.cssSelector("#t1-results > #t1-list5 > tbody > tr.r1")).size();
for(int i=1;i<=size();i++)
{
    String travelname = driver.findElement(By.cssSelector("#t1-results > #t1-list5 > tbody > tr.r1 > td.i1"))
}

让我知道上面的脚本是否适合你。
