使用XPath进行搜索时，HtmlElements可以找到3个元素，而不是块中的一个元素 [英] HtmlElements finds 3 elements instead of only one in block when searching with XPath

问题描述

我有一个方块:

@Block(@FindBy(xpath = "//tr[contains(@class,'bg-success')]"))
public class ShareContentRowBlock extends HtmlElement {

   @FindBy(xpath = "//h3[@class='fileName']/span/a")
   private TextBlock contentNameText;

   public String getContentName() {
       return contentNameText.getText();
   }

   .... // some other elements and methods
}

我描述了一个页面:

public class DocumentLibraryPage extends SitePage {

    private List<ShareContentRowBlock> shareContentRowBlocks;

    .....

    public ShareContentRowBlock getShareContentRowBlock(String name){
        for (ShareContentRowBlock conentRowBlock: shareContentRowBlocks){
            if(name.equals(conentRowBlock.getContentName())){
                return conentRowBlock;
            }
        }
        return null;
    }
}

当我尝试获取元素时，它返回的不完全是我想要看到的元素.

When I try to get element, it returns not exactly element that I want to see.

我有带有元素树的html:

I have html with elements tree:

   html
       h3.fileName
         span 
             a
       h3.fileName
         span 
             a
       table.bg-success
         h3.fileName
             span 
                 a

我想在表中获取元素<a>，但是它返回所有3个<a>元素. 当我尝试调试时，它实际上会忽略父块xpath来查找所有<a>元素.

I want to get element <a> inside table, but it returns all 3 <a> elements. When i try to debug it really finds all <a> elements with ignoring parent block xpath.

这有什么问题?我需要更改选择器，还是以其他方式描述块?

What wrong with it? Am I need to change selectors, or describe block in other way?

推荐答案

以"//"开头的xpath定位器表示绝对块位置.为了进行相对搜索，您应该以"."开头:

Starting xpath locator with "//" means absolute block position. In order to make relative search you should start it with ".":

@Block(@FindBy(xpath = "//tr[contains(@class,'bg-success')]"))
public class ShareContentRowBlock extends HtmlElement {

   @FindBy(xpath = ".//h3[@class='fileName']/span/a")
   private TextBlock contentNameText;

   public String getContentName() {
       return contentNameText.getText();
   }

   .... // some other elements and methods
}
