For examle:
<div id="outer">
<div id="a">
<div class="b"> 11111111111</div>
<div class="b"> 22222222222222</div>
</div>
</div>
Now I want to match the elements of id is a, and replace it to empty, but I found I can't, because id="a" is not the outer div. This is my c# code ,it will match the last Tag.
Regex regex = new Regex(@"<div id=""a([\s\S]*) (<\/[div]>+)");
Try this:
var doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);
var divs = doc.DocumentNode.Descendants().Where(x => x.Name == "div" && x.Id == "a");
foreach (var div in divs.ToArray())
{
div.InnerHtml = "";
}
var result = doc.DocumentNode.OuterHtml;
The result I get is:
<div id="outer">
<div id="a"></div>
</div>
