Selenium检查属性是否包含Java中字符串的一部分

Question

So I have a webpage where the Id's of certain elements are generated dynamically with certain parts changing and certain parts being constant like so:

<div id= "xxxdiv" title= 'this title'>
  <p id = "xxxp">
  <table id = "xxxtable" title = 'not derp'>
         <div id = "yyyydiv">
           <table id = "yyytable" title= 'derp'>
             <table id = "yyytable2" title = 'not derp'>
               <table id = "zzztable" title = derp>

I'm trying to do some dynamic lookups on the page that can look for a given element where the id contains a known value. For instance, I do not always know how many nested elements might exist so the number that gets generated on the end can vary. So I would like to find an element by xpath where the @title = not derp and the @id contains yyy. How can I accomplish this?

Answer 1

driver.findElement(By.xpath("//table[@title='not derp' and contains(@id, 'yyy')]"));

会找到与您的搜索条件相匹配的第一个元素，这将是HTML代码段的<table id = "yyytable2" title = 'not derp'> 。

Answer 2

There are a whole host of relational and logical operators you can use. In this case, assuming you're looking for the table element, you can use: //table[@title='not derp' and contains(@id,'yyyy')]

Answer 3

I would like to find an element by xpath where the @title = not derp and the @id contains yyy

I would suggest you cssSelector instead, because using By.cssSelector() to locate an element is much faster than By.xpath() in performance. So you should try as below :-

driver.findElement(By.cssSelector("table[id *= 'yyy'][title = 'not derp']"));
