Question

html如下：

<OBJECT id="IndiDocX" CODEBASE="/IndiDoc.CAB#version=4,5,0,132" width=500 height=201 VIEWASTEXT>
.........
<PARAM NAME="IDNUM" VALUE="4090">
<PARAM NAME="Editable" VALUE="false">
<PARAM NAME="Nodelfiles" VALUE="\adad.xlsx\1111.sep\2222.gw">

我想通过IE驱动程序中的xpath获取PARAM[@name="Nodelfiles"]的值我的代码：

attr = driver.find_element_by_xpath('//object[@id="IndiDocX"]/param[@name="Nodelfiles"]').get_attribute('value')

消息：

Traceback (most recent call last):

    main()

    attributeValue = self.parent.execute_script(
  File "C:\Users\A\AppData\Local\Programs\Python\Python38\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 634, in execute_script
    return self.execute(command, {

    self.error_handler.check_response(response)
  File "C:\Users\A\AppData\Local\Programs\Python\Python38\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.StaleElementReferenceException: Message: Error executing JavaScript

如何获得价值我用这个可以通过索引获取，但是不能用名字

js = 'return document.getElementById("IndiDocX").getElementsByTagName("PARAM")[24].getAttribute("value");'
attr = driver.execute_script(js)
print(attr)

24是索引

使用diriver.page_souce来gei html，并使用re.findall（）来匹配数据

使用硒IE驱动程序获取<object>中<param>的值
