Java 前一个兄弟姐妹不工作

请尝试使用下面的xpath，它会起作用

// Option 1
String xpath = "//div[div/span[@role='columnheader' and text()='Product']" + 
"//span[contains(@class, 'ag-icon-menu')]"

driver.findElement(By.xpath(xpath)).click();


// Option 2
String xpath = "//div[div/span[@role='columnheader' and text()='Product']"
driver.findElement(By.xpath(xpath))
      .findElement(By.cssSelector("span.ag-icon-menu"))
      .click()

---

当class属性有多个唯一值时，我们可以使用“AND”条件

选择第一个类是

ag-header-icon

，而不是

g-header-icon

。您缺少

a

。仍不清楚要单击哪个元素。路径

//previous sibling:：span

非常没有意义-它会选择文档中某个元素的前一个同级元素。我怀疑前导“/”被添加为magic fairy dust，应该去掉。您需要提供一些匹配的节点才能得到好的答案。

WebElement pipeline = driver.findElement(By.xpath("//span[text()='Product']"));
WebElement parent = pipeline.findElement(By.xpath(".."));
WebElement sibling = parent.findElement(By.xpath("(//preceding-sibling::span[@class='g-header-icon ag-header-cell-menu-button']/span)[1]"));
sibling.click();

// Option 1
String xpath = "//div[div/span[@role='columnheader' and text()='Product']" + 
"//span[contains(@class, 'ag-icon-menu')]"

driver.findElement(By.xpath(xpath)).click();


// Option 2
String xpath = "//div[div/span[@role='columnheader' and text()='Product']"
driver.findElement(By.xpath(xpath))
      .findElement(By.cssSelector("span.ag-icon-menu"))
      .click()

driver.findElement(By.xpath("//span[contains(@class,'ag-icon') and contains(@class,'ag-icon-menu')]")).click();
