问题

I am very new at Java and Selenium so my apologies in advance if my question sounds a bit primary.

I use:

driverChrome.findElements(By.className("blabla"));

to find elements which have "blabla" as their className, for example:

<span class="blabla" title="the title">...</span>

Now, what if I want to find all elements by their other attributes? something like:

driverChrome.findElements(By.titleValue("the title"));

This is the code that I am currently using to do this task:

List<WebElement> spans = driverChrome.findElements(By.tagName("span"));

for (WebElement we : spans) {

    if (we.getAttribute("title") != null) {
            if (we.getAttribute("title").equals("the title")) {
                    ...
                    break;
            }
    }

}

but it is not fast and easy to use.

There are many methods while archiving an element by XPath

1 Absolutely path

<html>
  <body>
     <div>
       <form>
          <input id="demo"/>
       </form>
     </div>
   </body>
 <html>

To get the 'input' tag

xpath="/html/body/div/form/input"

2 Relative path

<html>
  <body>
     <div>
       <form>
          <input id="demo"/>
       </form>
     </div>
   </body>
 <html>

To get the 'input' tag

xpath="//input"

3 Index

<html>
  <body>
     <div>
       <form>
          <input id="demo1"/>
          <input id="demo2"> 
       </form>
     </div>
   </body>
 <html>

To get the input 'demo2'

xpath="//input[1]"

4 Arbitrary single attribute

<html>
  <body>
     <div>
       <form>
          <input id="demo1"/>
          <input id="demo2" foo="bar"> 
       </form>
     </div>
   </body>
 <html>

To get input 'demo2'

xpath="//input[@id='demo2']" (equivalent to By.id)

xpath="//input[@foo='bar']"

5 Arbitrary multiple attributes

<html>
    <body>
     <div>
       <form>
          <input id="1" type="submit" />
          <input id="2" foo="bar"/>
          <input id="3" type="submit" foo="bar"/> 
       </form>
     </div>
   </body>
 <html>

To get 3rd input

xpath="//input[@type='submit'][@foo='bar']"

xpath="//input[@type='submit' and @foo='bar']"

If use xpath="//input[@type='submit' or @foo='bar']" here you'll get an array. You can get the List by driver.findElements(By.xpath(xpath)) (java). Otherwise you'll get the first element(If you just use driver.findElement). Because all of the 3 input elements meet your condition 'or' and it gives you the first one.

6 Contains attribute

<html>
    <body>
     <div>
       <form>
          <input id="1" type="submit" />
          <input id="2" foo="bar" daddy="dog"/>
          <input id="3" type="submit" foo="bar"/> 
       </form>
     </div>
   </body>
 <html>

To get the second input

xpath="//input[@daddy]"

Because only the second one has attribute 'daddy'

7 Inner searching

 <html>
    <body>
     <div>
       <form>
          <input id="input1" daddy="dog" />
          <input id="input2" daddy="pig"/>
       </form>
     </div>
     <div>
       <form>
          <input id="input3" daddy="dog" />
          <input id="input4" daddy="apple"/>
       </form>
     </div>
   </body>
 <html>

To get the second div

xpath="//div[.//input[@daddy='dog'] and .//input[@daddy='apple']]"

Overall those are all I can work out for now. Hope it helps.

回答2:

You can do it using xpath

driverChrome.findElement(By.xpath("//*[@yourAttribute='value']"));

For example:

driverChrome.findElement(By.xpath("//*[@title='the title']"));

回答3:

You can also achieve this using CSS locators.

By.cssSelector ("span[title='the title']")

CSS selector are rumoured to be faster.

We cover a number of locating techniques in Selenium WebDriver in Practice: http://selenium-webdriver-in-practice.github.io

回答4:

There a number of options you can go for.

by css selector
by xpath
by id
by tag For easy reading tutorials, please follow the links below: http://www.w3schools.com/xsl/xpath_syntax.asp http://www.w3schools.com/cssref/css_selectors.asp

All above is using element attributes, alternatively, you can use relationship among elements. Such as sibling, parents and children.

Please refer to this awesome link for more details. http://scraping.pro/res/xpath-cheat/xpath_css_dom_recipes.pdf

There are also very well supported and established frameworks for you to use. For example, robot framework, it will vastly simplify your codes.

回答5:

 WebElement element = driver.findElement(By.xpath(".//*[@id='ctl00_PLSMainContent_AssistTaskList_assistListView']/div/table/tbody/tr/td[7]/span"));

 System.out.println("get attribute is --> " + element.getAttribute("Title"));
