我试图遍历DOM中的每个表行元素并执行String Assert以查看它是否包含所需的文本。当我调试我的代码并查看我的变量tableRows的Count时，它显示它包含158个项目，而实际页面上几乎没有。我在这里做错了什么？
C＃：
[Test]
public void FilterByCompanyTest()
{
const string filter = "Company";
var table = this.Driver.FindElement(By.ClassName("index-table"));
var tableRows = table.FindElements(By.XPath("//tr"));
for (var i = 1; i < tableRows.Count; i++) {
StringAssert.Contains(filter, this.Driver.FindElement(By.XPath("//tr[" + i + "]/td[6]")).Text);
}
}
HTML：
<div class="table-responsive index-table">
<table class="table">
<thead>
<tr>
<th>#</th>
<th class="ticket-title">Title</th>

<a href="?companyID=-1&technicianID=-1&statusID=0&typeID=&orderBy=priorityAsc">

答案 0 :(得分：1)
XPath需要更多的帮助来告诉它有关上下文（即在元素内搜索）：
var tableRows = table.FindElements(By.XPath(".//tr"));
请注意。。这会将查询过滤到该表中的tr元素。
另外需要注意的是，这可以在没有XPath的情况下完成：
var tableRows = table.FindElements（By.TagName（“tr”））;
我还要提到的是，就性能而言，您可能会发现通过XPath专门定位元素（即不用于循环整个批次）会更快更高效。
