python 判断xpath
时间: 2023-11-07 11:05:14 浏览: 46
在Python中判断XPath的存在可以使用自定义方法来实现。首先,使用try-except语句来捕获异常,如果能够成功通过XPath定位到元素,则返回True,否则返回False。以下是一个示例的自定义方法:
```
def NodeExists(xpath):
try:
driver.find_element_by_xpath(xpath)
return True
except:
return False
```
在具体使用时,可以通过调用该方法来判断XPath是否存在。例如:
```
if NodeExists("//*[@id='tsf']/div<span class="em">1</span><span class="em">2</span><span class="em">3</span>
