Html代码

<table class="adminlist" width="100%" cellspacing="0" cellpadding="0" border="0">
<tbody>
<tr data-bind="if: RowCounts>0, attr: {StatusId: Id, DescName:Name}" statusid="2" descname="Abandoned"></tr>
<tr data-bind="if: RowCounts>0, attr: {StatusId: Id, DescName:Name}" statusid="1" descname="Active">
<td style="width: 5%;">
<input type="checkbox" data-bind="attr: { accesskey: Id }" accesskey="1">
</td>
<td class="country">
<span data-bind="text:Name">Active</span>
 (
<span data-bind="text:RowCounts">20</span>
)
</td>
</tr>

我们怎样才能找到＆＃34; td＆＃34;元素是否存在与上表，基于上面的第一行没有td元素但第二行它有一个td元素

java代码

Hashtable<String, Integer> renewalStatus = new Hashtable<String, Integer>();
        List<WebElement> activeAssetStatus = driver.findElements(By
                .xpath("//*[@id='divPatPortfolioStatusCount']/table/tbody/tr"));

        for (int i = 1; i <= activeAssetStatus.size(); i++) {
            List<WebElement> statusValue = activeAssetStatus.get(i)
                    .findElements(By.tagName("td"));

            if (statusValue.size() > 0) {
                WebElement al = driver
                        .findElement(By
                                .xpath("//*[@id='divPatPortfolioStatusCount']/table/tbody/tr["
                                        + i + "]/td[2]"));

                String mainText = al.getText();
                final Pattern p = Pattern.compile("(.*?)\\s*\\((.*?)\\)");
                final Matcher m = p.matcher(mainText);
                m.find();
                String name = m.group(1);
                String count = m.group(2);
                renewalStatus.put(name, Integer.parseInt(count));
            }
        }
}

以上代码无法在哈希表中收集和存储td值它的产品＆＃34; NoSuchElementException＆＃34; 因为在if条件中我的值为1所以它产生了这个异常，我怎么能用td值收集相应的行

Answer 1

List <WebElement> allTrElements = driver.findElements(By.xpath("//table[@class='adminlist']/tbody/tr"));

for(int i= 0;i<allTrElements.size();i++){
   List<WebElement> allTdElements = allTrElements.get(i).findElements(By.tagName("td"));
   if(allTdElements.size() > 0 ){
      // if confirms <tr> contains <td>
   }
}

Answer 2

WebDriver mainDriver = new ChromeDriver();

//get the table element
WebElement eleTable = mainDriver.findElement(By.tagName("table");

//get the list of row elements of table
List<WebElement>tableRowList = eleTable.findElements(By.tagName("tr"));

for(int i = 0 ; i < tableRowList.size(); i++) {
    //take individual rows
    WebElement rowElement = tableRowList.get(i);

    //get the list of td elements
    List<WebElement> dataElement = rowElement.findElements(By.tagName("td"));

    if(dataElement.size() > 0) {
        //if size > 0, there are td elements in it.
    }
}

如何找到td元素是否存在 - 使用java的selenium webdriver
