Specifying multiple conditions in xpath

问题

I want to select all the tags with <td class='blob-code blob-code-addition'> and <td class='blob-code blob-code-deletion'> . So I am trying to include or condition here between the two predicates. It does not work. However, if I include only one of the two classes it works . What is the problem here? Something is wrong with the syntax.

By getChanges = By.xpath("//td[@class='blob-code blob-code-addition'] or  //td[@class='blob-code blob-code-deletion']");

回答1:

You want to specify that like the following:

//td[contains(@class,'deletion') or contains(@class,'addition')]

or

//td[contains(@class,'blob-code blob-code-addition') or contains(@class,'blob-code blob-code-deletion')]

If you want to do a tag independent search then you can simply use

//*[contains(@class,'blob-code blob-code-addition') or contains(@class,'blob-code blob-code-deletion')]

From your answer it looks like you are trying to concatenate two different xpaths

However, contians() is not mandatory here. You also can do without this

//*[(@class='blob-code blob-code-addition') or (@class='blob-code blob-code-deletion')]

回答2:

what works for me is below expression using "|" character inside my expression-

By element = driver.findElement(By.xpath("//button[@clas='xyz'] | //button[@clas='abc']"))

I used above expression for JAVA + Selenium + Maven project

using pom: @FindBy(xpath ="//span[contains(@class,'vui-menuitem-label-text') and normalize-space(.) = 'Clone']")

回答4:

To select all the tags with:

• <td class="blob-code blob-code-addition">
• <td class="blob-code blob-code-deletion">

You can use either of the following Locator Strategies:

• Using xpath through class attribute with or clause:

  //td[@class='blob-code blob-code-addition' or @class='blob-code blob-code-deletion']
  

• Using xpath through single class attribute with or clause:

  //td[contains(@class,'blob-code-addition') or contains(@class,'blob-code-deletion')]
  

• Using xpath through partial class attribute with or clause:

  //td[contains(@class,'addition') or contains(@class,'deletion')]
