I am building a forum and I want to use forum-style tags to let the users format their posts in a limited fashion.Currently I am using Regex to do this.As per this question:How to use C# regular expressions to emulate forum tags. The problem with this,is that the regex does not distinguish between nested tags.Here is a sample of how I implemented this method:
public static string MyExtensionMethod(this string text){return TransformTags(text);}
private static string TransformTags(string input)
{string regex = @"[([^=]+)[=x22']*(S*?)['x22]*](.+?)[/(1)]";
MatchCollection matches = new Regex(regex).Matches(input);
for (int i = 0; i < matches.Count; i++)
var tag = matches[i].Groups[1].Value;
var optionalValue = matches[i].Groups[2].Value;
var content = matches[i].Groups[3].Value;
Now,if I submit something like [quote] This user posted [quote] blah [/quote] [/quote] it does not properly detect the nested quote.Instead it takes the first opening quote tag and puts it with the first closing quote tag.Do you guys recommend any solutions?Can the regex be modified to grab nested tags?Maybe I shouldn't use regex for this?
I want to implement readmore/less feature. i.e I will be having html content and I am going to show first few characters from that content and there will be a read more link in front of it. I am currently using this code :
var txtToHide= input.substring(length);
var textToShow= input.substring(0, length);
var html = textToShow+ '<span class="readmore"> … </span>'
+ ('<span class="readmore">' + txtToHide+ '</span>');
html = html + '<a id="read-more" title="More" href="#">More</a>';
Above input is the input string and length is the length of string to be displayed initially. There is an issue with this code, suppose if I want to strip 20 characters from this string:
"Hello <a href='#'>test</a> output", the html tags are coming between and it will mess up the page if strip it partially. What I want here is that if html tags are falling between the range it should cover the full tag i.e I need the output here to be "Hello <a href='#'>test</a>" . How can I do this?

I have a fck editor in which the user enters some text. And in the code i want to strip the class,id attributes of the text posted. I know this can be done through regular expressions And i have written some code to do so but unfortunately it's not working.
private string RemoveScripts(string input)
{
string re1 = "(.*?"; // Non-greedy match on filler
string re2 = "(class)"; // Word 1
string re3 = "(=)"; // Any Single Character 1
string re4 = "(".*?"))"; // Double Quote String 1
string re5 = "(id)";
Regex regClass = new Regex(re1 + re2 + re3 + re4, RegexOptions.IgnoreCase | RegexOptions.Singleline);
Regex regID = new Regex(re1 + re5 + re3 + re4, RegexOptions.IgnoreCase | RegexOptions.Singleline);
input = regClass.Replace(input, new MatchEvaluator(ReplaceClassID));
input = regID.Replace(input, new MatchEvaluator(ReplaceID));
return input;
}
private string ReplaceClassID(Match m)
{ return ""; }
I am creating a web form for employees to submit recipe's on a web form. The fields are recipe name, ingredients, and the recipe instructions. Majority of the time, employee's will be copying/pasting the text from a word document. Currently I am using the ajax editor control. I know there is a "Paste from Word" button that can be used but all the users are not going to know to use the button.
They may just do a right click to paste or the ctrl v to paste. When this is done, all the html tags from Word are pasted as well. I want to be able to remove the tags.
how one might go about implementing your own custom tags in JS pages served by ASP.NET?
Basically what I am looking to achieve is a way of creating "includes" for my Javascript files by adding some code such as.
//Include Src="MyJavascriptFileLocation.JS"
And then having the ASP.Net handler serve my javascript file but also dynamically append the referenced javascript file to the location where the include is written.
I am creating a custom control and was wondering if it is possible to render any JavaScript in the head tags of the page it is placed on? I am thinking I would need to use the FindControl method, but am not sure what I need to bind to. I am thinking the page object? Let me know if I am thinking in the right direction or if there is another option.
My only concern with the above mentioned idea is that how do I render all my content while placing some code in the head tags?
I am successfully including a javascript resource by calling ScriptManager.RegisterClientScriptResource at the end of OnPreRender in my custom control. However, the resulting script tag is being included before the automatically included script tags that define things like Type and Sys which my script depends on. I thought they were defined in the order that they are included but I can't include my script any later then I am. How can I control the order in which the script tags are included?
View 2 Repliesi'm trying to find all the anchor tags and appending the href value with a variable.
for example
<a href="/page.aspx">link</a> will become <a href="/page.aspx?id=2">
<A hRef='http://www.google.com'><img src='pic.jpg'></a> will become <A hRef='http://www.google.com?id=2'><img src='pic.jpg'></a>
I'm able to match all the anchor tags and href values using regex, then i manually replace the values using string.replace, however i dont think its the efficient way to do this.Is there a solution where i can use something like regex.replace(html,newurlvalue)

View 2 RepliesIs there a way to apply your own CSS tags to <li> tags when using ASP .NET 4.0 menu control? For example, say I have an external style sheet that has tags "class1", "class2", "class3", and etc. I want to apply "class1" to the first menu item. Then if menu item is selected, I want to apply "class2" and if it's not selected, "class3". I played with various 'Static' styles, but just can't get it work. I finally gave up and created my own menu control that extends ASP .NET menu control and provides my own custom rendering. This works, but I'm wondering if there is a way to get it work with built-in menu control.
