Web Forms :: Create RegEx Function That Would Retrieve Inner Html Of Div?
Sep 15, 2010
I have been trying for a long time to create regEx function that would retrieve inner html of div but still no luck. What I want to do is to retrieve inner html of div with specific class.
As you can see inner html itself can contain div tag and have no fixed structure (though will have correct html structure - opening and closing tag). So, how to get the inner html of div with class "Product".
How do I solve the problem below? I'm creating a simple content management system, where there is a HTML template with specific markup that denotes where content should be:
Separate from this, there is content in a database field that looks a little like this:
<!-- #BeginEditable "Body1" -->This is Test Text<!-- #EndEditable --><!-- #BeginEditable "Extra" -->This is more test text<!-- #EndEditable -->
As you can guess I need to merge the two, that is, replacing
<!-- #Editable "Body1" -->
with: This is Test Text. I've begun the code here. But I'm having problems using the Regex Replace function that should be located at the very bottom of that For/Each.
//Html Template string html = "<html><head></head><body><!-- #Editable "Body1" --><p>etc etc</p><!-- #Editable "Extra" --></body></html>"; //Regions that need to be put in the Html Template string regions = "<!-- #BeginEditable "Body1" -->This is Test Text<!-- #EndEditable --><!-- #BeginEditable "Extra" -->This is more test #EndEditable -->"; //Create a Regex to only extract what's between the 'Body' tag Regex oRegex = new Regex("<body.*?>(.*?)</body>", RegexOptions.Multiline); //Get only the 'Body' of the html template string body = oRegex.Match(html).Groups[1].Value.ToString(); // Regex to find sections inside the 'Body' that need replacing with what's in the string 'regions' Regex oRegex1 = new Regex("<!-- #Editable "(.*?)"[^>]*>",RegexOptions.Multiline); MatchCollection matches = oRegex1.Matches(body); // Locate section titles i.e. Body1, Extra foreach (Match match in matches) { string title = oRegex1.Match(match.ToString()).Groups[1].ToString(); Regex oRegex2 = new Regex("<!-- #BeginEditable "" + title + ""[^>]*>(.*?)<!-- #EndEditable [^>]*>", RegexOptions.Multiline); // // // Replace the 'Body' sections with whats in the 'regions' string cross referencing the titles i.e. Body1, Extra // // // }
I need to create something which is like an Add friend function in my website which works like this:
1) User types in name of the person he wants to search in the search field and clicks enter
2) on the same page, the search result will come out with an "add friend" button beside every name
3) when the user clicks the "add friend" button, he will be brought to another page (or pop up with a message box?) with a text message field to send to the friend, and a submit button to submit the friend request.
4) over at the Friend's page, he will be able to view the add friend request and decide whether to accept or deny the friend request.
I am using a linkbutton iside a gridview.... i need to get the text of the link button in another function. how can get that ... i tried find control .. but its not working.... I created the link button from other function which executes just b4 this function...
I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:
function setData(associateValue, reviewDateValue) { var associate = document.getElementById("Associate"); var reviewDate = document.getElementById("ReviewDate"); associate.value = associateValue; reviewDate.value = reviewDateValue; }
Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>
The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.
above string i have displayed in front end thrgh response.write i.e by assigning string abc to viewstate. also i am tryin to genetrate above input fields from database , so i have to make it dynamic in a loop. so when a user updates any of those dynamically created fields i need to retreive those values in a loop
something like this :
field1.text , field2.text ......so on till fieldn.text ....i want to assign these values to array
like :
string[] arr1 = new string[nooffields]; arr1[i] = fieldi.text;
I'm trying to generate a block of HTML code using a VB.net function. I created a function in a class. THe function generates a string that contains html and a strValue that I would like displayed.
public shared function getMyHTML(strValue) return string str1 = "<table><tr><td><%=strValue%></td></tr></table>" end function
I added a call to this function in the page_Load event to generate a string on the page. In the aspx page, I have the following code:
<% =stValue %>
The string value passed to the function appears on the page, but none of the html or formatting that is passed. When I view the page using View source, all the HTML is there exactly as it should be. I read this may have something to do with viewstate. But don't know what to use and where to place it to override it.
I'm having a little trouble with using regex in linq. I want to be able to perform a search on values in my database. The goal is to insert a value into the regex and then use that to search a column in a table in my database for that term. I want it to work so that it gets all exact matches and also returns matches in which the search term is a substring of the term in the column.
I was trying to follow this tutorial on msdn, but it doesn't quite fit perfectly with my problem:
I have a public property that I use to store a GUID in the viewState:
Property myGUID() As Guid Get Return CType(Me.ViewState("myGUID"), Guid) End Get Set(ByVal value As Guid) Me.ViewState("myGUID") = value End Set End Property
I include this code on many pages in my website...is there any way to migrate this to a common code file, so I don't have to repeat it on each page? If I try to add it to a class file, the "Me" part of course is out of scope.
I have a function that gets the position of a control.
[Code]....
All the function needs is an htmlcontrol being fed to it as the parameter (elemRef). I can declare a variable in Javascript of the same content page but different function and pass the parameter successfullly getting returned values. For example, if I have the following function:
function (getPosition) { var txtBox1 = document.getElemendById('<%=txtBox1.ClientID %>'); getPos(txtBox1); }
I will get the coordinates of the control txtBox1. But how can I accomplish this if I am calling this function from a javascript function or codebehind of the Master Page, or codebehind of the same content Page.
I am trying to create an HTML button that can use a C# server side delete function. since I don't know how many results I will have at the page, the control is created dynamically when the end user searches for current Messages:
Recently i am develop a tuition center management systemNow i want to show a timetable which admin can view and know what time the class room is emptyMy timetable is : On the top of x-axis is time (8am, 9am, ...)On the left of y-axis is date (monday, tuesday, ...)In database i will define the start time and end time for each class
I have a large string containing a custom HTML tag (xxx). The tag also has two attributes. How would I retrieve the value of the two attributes and then place the tag and its content with a new string derived from those two attributes?

How to Create a function for Prefix generation on each insert row ?I have a table with ID as primary and is identity and increment by 1. and POID another column.Now I need to generate a function like this.In POID Column on each insert I need to set prefix like this
I'm coding an ASP.NET page, with VB code behind. When the user clicks a button on the page, I send them an email with information and instructions. Rather than sending a plain text email, I send a nice, pretty, HTML-formatted one. Right now, I'm doing this in a way that I KNOW will be difficult to maintain. That is, I'm straight up writing out all of the html. i.e.
and so on. Is there a way to create an aspx page (with vb code behind), and send the html of that page in the body of the email? The information is dynamic, so this pseudo-page would need logic in the on-load event to format the html correctly.
