如何通过getText()从html中的多个子节点中提取动态文本

2022-01-16 00:00:00 selenium selenium-webdriver webdriverwait webdriver java

我们有一个包含一些硬编码文本的 Div 和一个包含一些动态文本值的 span(请参阅下面的 HTML 代码以获得更多理解).结果文本为:1 任务从 'XYZ' 更新为 'ABC'

但是当我使用 Selenium 定位器检索时，即

final String 实际 = $("#bulk_update_confirmation").text();

那么实际只包含要更新的任务".缺少所有动态文本.

HTML代码如下(使用的浏览器是chrome)

 解决方案 在尝试提取总文本之前，例如1 任务从 'XYZ' 更新为 'ABC' 您可以诱导 WebDriverWait 让所有三个子  元素都可见 并且您可以使用以下解决方案:
new WebDriverWait(driver, 10).until(ExpectedConditions.and(ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[@id='taskCountSpan']")),ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[@id='oldStatusSpan']")),ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[@id='newStatusSpan']"))));
We have a Div containing some hard coded text and span containing some dynamic text values (refer below HTML code for more understanding). 
The resultant Text is: 1 Tasks to be updated from 'XYZ' to 'ABC' 

but when I am retrieving using Selenium locator i.e. 
final String actual = $("#bulk_update_confirmation").text();
Then the actual contains only "Tasks to be updated from to". All the dynamic text are missing.

HTML code is as below (browser used is chrome)
<div id="bulk_update_confirmation" class="ui-dialog-content ui-widget-content" style="display: block; width: auto; min-height: 96.16px; height: auto;" scrolltop="0" scrollleft="0">
            <span id="taskCountSpan">1</span> Tasks to be updated from <span id="oldStatusSpan">'XYZ'</span> to <span id="newStatusSpan">'ABC'</span> <span id="desciptionSpan"> </span> <br>
            <hr>
            <div class="ui-dialog-buttonset">
                <button type="button" id="btn_bulk_update" onclick="updateBulkStatus()">Update</button>
                <button type="button" onclick="closeBulkUpdateRequest()">Cancel</button>
            </div>
        </div>

 解决方案 Before you attempt to extract the total text e.g. 1 Tasks to be updated from 'XYZ' to 'ABC' you can induce WebDriverWait for all the three child elements to be visible and you can use the following solution:
new WebDriverWait(driver, 10).until(ExpectedConditions.and(
    ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[@id='taskCountSpan']")),
    ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[@id='oldStatusSpan']")),
    ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[@id='newStatusSpan']"))
));
