hi,
I was in search of finding a regular expression that matches the anchor tag in HTML and updates the value of the href attributes.
i have gone through many of them but none supports the anchor tag in which the qoutes around href are not present i.e.
so here in the updated Regular expression that matches all kinds of anchor tag and then a small chunk of c# code to get and update the value of href attribute.
public string UpdateHTMLAnchorTag(string input)
{
string initialURL = PLACE THE ABOVE REGULAR EXPRESSION HERE
Regex regex = new Regex(initialURL, RegexOptions.IgnorePatternWhitespace | RegexOptions.IgnoreCase);
MatchCollection matches = regex.Matches(input);
string ma = string.Empty;
foreach (Match m in matches)
{
ma = m.Result("${url}");
input = input.Replace(tempMa, "UpdatedMA");
}
return input;
}

Events in Community server 2008.5
I was assigned a task to write Events module in community server 2008.5, Many ways i looked for but dint find any good one to get ma work done, I decided to make a complete custom module for this purpose but again searching, Tags , blah blah ... y to make whats already done so i decided to modify a blog post and make it look like event.
lets begin what i did.
first of all events sud have some customized fields like location, Map url , start date, start time.
simply go to the community server Database and make table for all the customized fields.
just one this you need to append to it is a POST Id from cs_posts table. so that we can use the basic post functionality with events.
Okay now just goto the control pannel make a new blog. One important this "DONOT FORGET TO MAKE A NEW GROUP FOR THE BLOG". when you are dont with this just goto the CS code. navigate to folder Controlpannel> blogs > PostEditor.aspx
this is where we need to place the Extended module .
In order to make an extended module create a Class library project. Import all the DLL from the bin directory of CS Code.
now we need to create a SUB FORM but this time we wont be extending a user registration module we will be extending Blog post module.
========================================================================

// Class Custom Function will define all the Functions required in Custom modules

cs.getPostByPostId(cs);

}
if (string.IsNullOrEmpty(EventStartDate.Text))

CS.insertEventDetails(p.PostID, EventStartDate.Text,
EventEndDate.Text, EventLocation.Text);
}
}
}

In the Above subform code you will be finding a CS class this is the custom class added in the community server class library project. In this class we will just interact with our database to fetch the Events details.
Now the Events module admin is there its time to change the PostEditor page to show updated fields only for events.

===========================================================================
In tyhe above code you will find a value, Where group ID is set to "16" this 16 is the Id of the group which was assigned to BLog that we made for events.
<csblog:grouppropertyvaluecomparison id="GroupPropertyValueComparison1" comparisonproperty="GroupId" runat="server" operator="EqualTo" comparisonvalue="16">
this is all for the Admin Side.
When you will be opening the Blog Post for events extra fields will be visible to you that will be saved in your own table.
I will soon be writing about the showing event to the Community server users.
Hope this Blog helped ya...
Cheers.
