如何在 Selenium WebDriver 中获取元素的文本，而不包含子元素文本? [英] How to get text of an element in Selenium WebDriver, without including child element text?

问题描述

这是一些<div id="b">text</div>

获得这是一些"并非易事.例如，这将返回这是一些文本":

driver.find_element_by_id('a').text

一般来说，如何获取特定元素的文本而不包括其子元素的文本?

(我在下面提供了一个答案，但会留下这个问题，以防有人能想出一个不那么可怕的解决方案).

解决方案

这是一个通用的解决方案:

def get_text_ exclude_children(driver, element):返回 driver.execute_script("""返回 jQuery(arguments[0]).contents().filter(function() {返回 this.nodeType == Node.TEXT_NODE;}).文本();， 元素)

传递给函数的元素可以是从 find_element...() 方法获得的东西(即它可以是一个 WebElement 对象).

或者如果你没有 jQuery 或者不想使用它，你可以用这个替换上面的函数体:

return self.driver.execute_script("""var parent = 参数[0];var child = parent.firstChild;var ret = "";而(孩子){如果(child.nodeType === Node.TEXT_NODE)ret += child.textContent;child = child.nextSibling;}返回 ret;， 元素)

我实际上是在测试套件中使用此代码.

<div id="a">This is some
   <div id="b">text</div>
</div>

Getting "This is some" is non-trivial. For instance, this returns "This is some text":

driver.find_element_by_id('a').text

How does one, in a general way, get the text of a specific element without including the text of it's children?

(I'm providing an answer below but will leave the question open in case someone can come up with a less hideous solution).

解决方案

Here's a general solution:

def get_text_excluding_children(driver, element):
    return driver.execute_script("""
    return jQuery(arguments[0]).contents().filter(function() {
        return this.nodeType == Node.TEXT_NODE;
    }).text();
    """, element)

The element passed to the function can be something obtained from the find_element...() methods (i.e. it can be a WebElement object).

Or if you don't have jQuery or don't want to use it you can replace the body of the function above above with this:

return self.driver.execute_script("""
var parent = arguments[0];
var child = parent.firstChild;
var ret = "";
while(child) {
    if (child.nodeType === Node.TEXT_NODE)
        ret += child.textContent;
    child = child.nextSibling;
}
return ret;
""", element) 

I'm actually using this code in a test suite.
