HtmlListToArrayList (C#)

This function returns an ArrayList when you supply a string containing a list as the parameter. string text = "<ul><li class='foo' id='bar'>Item 1</li><li></li><li>Item 2</li><li>Item 3</li></ul>"; ArrayList ar; ar = HtmlListToArrayList(text); Response.Write(ar[1]); // returns 'Item 2' public System.Collections.ArrayList HtmlListToArrayList(string input) { string tag = @"</?(li)(\s+\w+=(\w+|""[^""]*""|'[^']*'))*\s*?/?>"; string pat = tag + "([^<]+)"; System.Collections.ArrayList ar = new System.Collections.ArrayList(); // Compile the regular expression. System.Text.RegularExpressions.Regex r = new System.Text.RegularExpressions.Regex(pat, System.Text.RegularExpressions.RegexOptions.IgnoreCase); foreach(System.Text.RegularExpressions.Match m in r.Matches(input)) { ar.Add(m.Groups[4].Value); } return ar; } Tags

Object Detection (JavaScript)

Object detection is a better way of writing JavaScript as the DOM cannot be faked like the user agent. Scripting Methods has a useful reference of DOM objects and what browser they are implemented in. It is also means forwards compatibility is less of an issue. So for instance, to get an element on a page (works in IE4+ and most modern browsers) : var myelement; if (document.getElementById) { myelement = document.getElementById("myelement"); } else if (document.all) { myelement = document.all["myelement"]; } if (myelement) { // do something } Tags: Web Developer Blog , JavaScript , DOM

Update to UrlQuery Class (C#)

Update to UrlQuery Class for easier working with Url's and QueryStrings in ASP.NET. Thanks to Levi Rosol ( UrlQueryString ) for the code. Previous versions: Url Manipulation (C#) - Jul 22nd, 2004, Url Manipulation v2 (C#) - Sep 22nd, 2004. You can now add a NameValueCollection to the QueryString. Replaces existing items when one with the same key exists in the collection. For redirecting to another page, including current page QueryString, supply the page location in the constructor: // current page is page.aspx?query=1 UrlQuery NewPage = new UrlQuery("newpage.aspx"); // redirect to newpage.aspx?query=1 Response.Redirect(NewPage.AbsoluteUri); More examples: UrlQuery MyPage = new UrlQuery("/path/to/file.aspx"); // parameters on the current page are added automatically // or to get the current page: MyQuery = new UrlQuery(); // add parameter MyPage["myparam"] = "myval1"; // add another parameter (or replace existing one) MyPage["my
