当我尝试解析值不正确时HTMLTableCell
,innerText
似乎我得到的是类名而不是文本。
现在奇怪的是,当我在调试中查看单元格(在 VS2010 中)时,我看到了正确的值我做错了什么?
进一步调查提出了这一点,当我在 VS2010 中查找值时,看起来这个 cell.innerText是“中心时间”并且((mshtml.HTMLTableCellClass)(cell)).innerText是"23:45"。问题是当我转换为 mshtml.HTMLTableCellClass 时它不会编译,所以我必须使用接口(为什么会这样?)
见下面的代码:
mshtml.HTMLDocument doc = MainBrowser.Document as mshtml.HTMLDocument;
if (doc != null)
{
mshtml.HTMLTable table = doc.getElementById("ecEventsTable") as mshtml.HTMLTable;
List<List<string>> textRows = new List<List<string>>();
foreach (mshtml.HTMLTableRow row in table.rows)
{
if (row != null && row.id != null && row.id.Contains("eventRowId"))
{
List<string> temp = new List<string>();
foreach (mshtml.HTMLTableCell cell in row.cells)
{
string text = cell.innerText;
if (text != null && text != "" && text != " ")
{
if (text.Contains("\r\n"))
text = text.Replace("\r\n", "");
temp.Add(cell.innerText);
}
}
if (temp.Count > 0)
textRows.Add(temp);
}
}
foreach (var row in textRows)
{
string str = String.Join(" ", row);
}
}
}
HTML 示例行:
<tr id="eventRowId_34599" onclick="javascript:changeEventDisplay(34599, this, 'overview');" event_timestamp="2014-02-24 01:30:00" event_attr_id="752">
