如何跳过表格行

Question

我创建了一个小脚本，它循环并删除表中不需要的行，但表中有一行无法删除。我怎样才能跳过那一行然后继续下一行呢？

这是我的脚本：

for(int i=0; i<25; i++){ 

     if(driver.findElement(By.xpath(PvtConstants.READ_ADVERTISRERS_ADVERTISER_IDS)).getText().contains("Skip Me")){ 
      //what to add here to skip the "Skip Me" text???? 
     } 

     //select the item in the table 
     driver.findElement(By.xpath(PvtConstants.READ_ADVERTISRERS_ADVERTISER_IDS)).click(); 

     //click the delete button 
     driver.findElement(By.xpath(".//*[@id='deleteAdv']")).click(); 

这是列的样子。我想跳过RealMedia，然后删除前后的所有项目。

HTML：

<table class="table smallInput dataTable" id="dataTableAdvertisers" "> 
<thead> 
<tr role="row" style="height: 0px;"> 
<th class="sorting_asc" tabindex="0" "></th> 
<th class="sorting" tabindex="0" "></th> 
<th class="sorting" tabindex="0" "></th> 
</tr> 
</thead> 
<tbody role="alert" aria-live="polite" aria-relevant="all"> 
<tr class="odd"> 
<td class=""> 
<a href="getadvertiserdetailsNew.do?advertiserKey=198909">RealMedia</a></td> 
<td class="">---</td> 
<td class="">---</td> 
<td class="">---</td> 
<td class="">---</td> 
</tr><tr class="even"> 
<td class=""> 
<a href="getadvertiserdetailsNew.do?advertiserKey=198910">teset2</a></td> 
<td class="">---</td> 
<td class="">---</td> 
<td class="">---</td><td class="">---</td> 
</tr><tr class="odd"> 

</tbody> 
</table>

尝试以下操作： 确保有获取列表之前一些等待（如果需要）。 此元素列表将查找该表下的所有a标记，并且for循环遍历该集合并删除该集合中没有与文本匹配的任何成员RealMedia。你不应该盲目地设置迭代器的上限。这会使程序循环不必要，这是一个不好的做法。

List<WebElement> elements = driver.findElements(By.cssSelector("#dataTableAdvertisers a")); 

for (WebElement element: elements){ 
    if (!element.getText().contains("RealMedia")){ 
     //select the item in the table 
     driver.findElement(By.xpath(PvtConstants.READ_ADVERTISRERS_ADVERTISER_IDS)).click(); 

     //click the delete button 
     driver.findElement(By.xpath(".//*[@id='deleteAdv']")).click(); 
    } 
} 

编辑：

By selector = By.cssSelector("#dataTableAdvertisers a"); 
List<WebElement> elements = driver.findElements(selector); 

//This just controls the loop. Iterating through the collection will return StaleElement ref exception 
for (int i = 0; i<elements.size(); i++){ 

    //Just want to delete the first item on the list 
    By xpath = By.xpath("//table[@id='dataTableAdvertisers']//a[not(.='RealMedia')]"); 

    if (driver.findElements(xpath).size()>0){ 
     WebElement element = driver.findElements(xpath).get(0); 

     element.click(); 

     //click the delete button 
     driver.findElement(By.xpath(".//*[@id='deleteAdv']")).click(); 
    } 
}
