find divs with id - regex

Question

Hi I'm very new to regex and I need some help with writing this or at least getting me started.
I would like to get all the divs on the page and put them into a string collection
there might be spaces between the < and div and a spaces between the < / div > thanks
I have tried the htmlaggilitypack but was experiencing issues thats why I am going this way
Dim reg As Regex = New Regex("<div(.*?)> </div")
Dim matches As string() = reg.Matches(htmlCode)
<div id="out">
<div id="one">
< div id="b"></div>
< div id="d"></div>
</div>
<div id="two">
<h1>fsdfsdf</h1>
< div id="a"><div id="a"></div></div>
< / div >
</div>

Answer 1

If you want to return a collection of divs by an ID value then you could use the following with HMTL agility pack:
protected void Page_Load(object sender, EventArgs e)
{
List<HtmlAgilityPack.HtmlNode> divs = GetDivsInner();
foreach (var node in divs)
{
Response.Write("Result: " + node.InnerHtml.ToString());
}
}
public List<HtmlAgilityPack.HtmlNode> GetDivsInner()
{
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.OptionFixNestedTags = true;
doc.Load(requestData("YOUR URL HERE"));
var divList = doc.DocumentNode.Descendants("div").Where(d => d.Attributes.Contains("id") && d.Attributes["id"].Value.Contains("YOUR ID VALUE")).ToList();
return divList;
}
public StreamReader requestData(string url)
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
StreamReader sr = new StreamReader(resp.GetResponseStream());
return sr;
}

Try
<\s*div.*>(.|\n)*<\s*/\s*div>
as your regex pattern. Have tested it with the following and it matches all
<div id='d'>
dsfdsfs
dsfdfd
</div>
< div >dave </div>
<div>home </ div>
<p></p>
however if you want to tweak it there are some great tools on the internet to test your regular expressions
