以 X 开头并以零或最小数字结尾的 Python XPath

Question

如果有人能帮助我编写实现以下目标的 XPath，我将非常感激:

• 查找具有以下 id 的元素:“revit_form_Button_50”，其中数字不断变化(可能是 30/40，但页面上的第一个似乎总是以 0 结尾)，并且标题还为“每日技术总计/”每日技术总计/员工每日总计报告”
• 或查找如下元素:“revit_form_Button_”+“minnumnumber”并包含图 block :“每日技术总计/每日技术总计/员工每日总计报告”

任何方法都会对我有很大帮助。

我的前两次失败的尝试:

browser.find_element_by_xpath("//*[starts-with(@id,'revit_form_Button_' ) and ends-with(@id,'0')]").click()

browser.find_element_by_xpath("//*[boolean(number(substring-before(substring-after(@id, 'revit_form_Button_'), '0')))]").click()

<div id="reporting_grid_CellReportTitle_10" class="rptCellReportTitle" widgetid="reporting_grid_CellReportTitle_10">

没有ends-with在 XPath 1.0 ，但你可以使用

"//*[starts-with(@id,'revit_form_Button_' ) and substring(@id,string-length(@id)) = '0']"

满足附加条件

and also has the title "Daily Tech Totals / Daily Tech Totals / Employee Daily Totals Report"

添加一个子句，例如

child::*[text() = 'full content of the child element here']

或

child::*[contains(text(),'text to match here')]

到您的 XPath。在您的示例中，子元素是 <b> 。所以，你也可以写child::b而不是child::* .

把它们放在一起:

"//*[starts-with(@id,'revit_form_Button_')
    and substring(@id,string-length(@id)) = '0'
    and child::*[text() = 'Daily Tech Totals / Daily Tech Totals / Employee Daily Totals Report']
]"

这是一个单一的 XPath 表达式。为了便于阅读，分成几行，但也可以是一行。
