<tr style="background-color:#FBF7EA;" onclick="javascript:__doPostBack('ctl00$MasterPlaceHolder$GrdHistory','Select$15')" onmouseout="javascript:setMouseOutColor(this);" onmouseover="javascript:setMouseOverColor(this);">

Is this possible, if so then how do i get the count without including the header row in the count. Please help me on this. Help will be appreciated.

Answer 1

在xpath下使用以排除第一行（标题）

//table[@id='ctl00_MasterPlaceHolder_GrdHistory']/tbody/tr[position()>1]

Answer 2

我建议 ：

 count(table[@id="ctl00_MasterPlaceHolder_GrdHistory"]/tbody/tr) - 1

Answer 3

试试这个代码：

int count = (driver.findElements(By.xpath("//table[@id='ctl00_MasterPlaceHolder_GrdHistory']/tbody/tr")).size()) - 1;
