Relative Xpath from list of WebElements
提问by so cal cheesehead
Is it possible to use a relative xpath after I've gathered a list of WebElements? If so what's the best way to do it?
在收集了 WebElements 列表后，是否可以使用相对 xpath？如果是这样，最好的方法是什么？
This is what I have:
这就是我所拥有的：
List <WebElement> rows = driver.findElements(By.xpath(rowsXpath));
int j = 1;
boolean foundCollector = false;
for(WebElement e : rows) {
String c = e.findElement(By.xpath("(//tbody)[" + j + "]//u[text()=\"" + collector + "\"])")).getText();
if(c.equals(collector)) {
foundCollector = true;
break;
}
++j;
}
the list rows contains individual rows with multiple columns and I'm trying to find the row which contains a particular name in a column. Within my for loop I was trying to use a relative xpath to look for an element, is this even possible? Or do I need to provide the whole xpath I used to find the rows with the additional xpath for the individual divs?
列表行包含具有多列的单个行，我正在尝试查找列中包含特定名称的行。在我的 for 循环中，我试图使用相对 xpath 来查找元素，这甚至可能吗？或者我是否需要提供整个 xpath 我用来查找带有单独 div 的附加 xpath 的行？
I'm not guaranteed the order of the columns which is why I have to do it this way.
我不能保证列的顺序，这就是为什么我必须这样做。
This is the xpath I used to obtain the rows:
这是我用来获取行的 xpath：
String rowsXpath = "//div[@id=\"QosDashpardPanelBottom\"]//div[@id=\"CollectorQoSPerformanceMetricsgrid\"]//div[contains(@class, \"x-grid3-row x-unselectable-single\")]";

Yes, this is definitely possible. See this:
是的，这绝对是可能的。看到这个：
// Find the outer element.
WebElement outer = driver.findElement(By.anything("whatever"));
// This doesn't work, it searches the whole page for the XPath expression.
WebElement inner = outer.findElement(By.xpath("//some/nasty/xpath"));
// This works! It takes the outer element as root.
WebElement inner = outer.findElement(By.xpath(".//some/nasty/xpath"));
Therefore, if I understood your need well, your XPath expression needs to look like this:
因此，如果我很好地理解您的需求，您的 XPath 表达式需要如下所示：
By.xpath("(.//tbody)[" + j + "]//div[text()=\"" + collector + "\"])")
EDIT(Holy cow, that's a lot of HTML and only a small amount of it is actually needed :).)
编辑（天哪，这是很多 HTML，实际上只需要一小部分 :)。
Now that I caught what you're after, I think you don't need this approach at all. Try this instead:
既然我抓住了你想要的东西，我认为你根本不需要这种方法。试试这个：
WebElement row = driver.findElement(By.xpath("id('CollectorQoSPerformanceMetricsgrid')//div[contains(@class,'x-grid3-row x-unselectable-single') and .//u[text()='" + collector + "']]"));
Only the XPath expression:
仅 XPath 表达式：
id('CollectorQoSPerformanceMetricsgrid')
//div[contains(@class,'x-grid3-row x-unselectable-single')
and .//u[text()='" + collector + "'] ]
Taken apart:
拆开来看：
FIND ELEM WITH ID = 'CollectorQoSPerformanceMetricsgrid'
id('CollectorQoSPerformanceMetricsgrid')
FIND ALL DIV ELEMS THAT CONTAIN 'x-grid3-row x-unselectable-single' IN @CLASS
//div[contains(@class,'x-grid3-row x-unselectable-single')
AND HAVE AN <U> DESCENDANT WITH TEXT EQUAL TO collector VARIABLE
and .//u[text()='" + collector + "'] ]
This finds you only the single row you need with a single command.
这只会为您找到一条命令所需的单行。
If you rather want to stick with your current solution, try:
如果您想坚持使用当前的解决方案，请尝试：
String rowsXpath = "id('CollectorQoSPerformanceMetricsgrid')//div[contains(@class, 'x-grid3-row x-unselectable-single')]";
List<WebElement> rows = driver.findElements(By.xpath(rowsXpath));
boolean foundCollector = false;
for(WebElement row : rows) {
if(!row.findElements(By.xpath(".//u[text()='" + collector + "']")).isEmpty()) {
foundCollector = true;
break;
}
}

Nowhere I found row (tr tag) in this xpath then how it will get rows count.
我在此 xpath 中无处找到行（tr 标记），那么它将如何获得行数。
String rowsXpath = "//div[@id=\"QosDashpardPanelBottom\"]//div[@id=\"CollectorQoSPerformanceMetricsgrid\"]//div[contains(@class, \"x-grid3-row x-unselectable-single\")]";
You need to construct xpath something like below to get row count in particular table
您需要构建类似于下面的 xpath 以获取特定表中的行数
int rowCount=driver.findElements(By.xpath("//table[@class='x-grid3-row-table']/tbody/tr"))
Or else if you want to find all columns in that table with particular name
否则，如果您想查找该表中具有特定名称的所有列
construct xpath like below
像下面这样构造xpath
int columnCount=driver.findElements(By.xpath("//table[@class='x-grid3-row-table']/tbody//tr//td[@name='RequiredName']"))
