.net - Remove Any HTML Within THE <TABLE> And </TABLE> Tags?
Dec 22, 2010
I have a html text file and I am trying to remove any HTML tags in tables, i.e. remove any HTML within THE <TABLE> and </TABLE> tags.
However, what's really weird is that the regex that I use, (?<=<table((?!</table).)*)<(?!/table)[^>]+>, works perfectly in PowerGREP or EditPad Pro, however, when applied in vb.NET (or Expresso) to the VERY SAME text, it does NOT work! I just use a simple replace method: newString = Regex.Replace(oldString, "(?<=<table((?!</table).)*)<(?!/table)[^>]+>", string.Empty, RegexOptions.IgnoreCase)?
I have an HTML document in .txt format containing multiple tables and other texts and I am trying to delete any HTML (anything within "<>") if it's inside a table (between <table> and </table>). For example:
=================== other text <other HTML> <table> <b><u><i>bold underlined italic text</b></u></i>
This is the format of the html, i just need to gett he users age and name, using reg ex i have so far:
Dim proxySourceHTML As New Regex("(?<=<tr bgcolor=""#ffffff"" class=""text"" height=10>"").*?(?="".*?"">)", RegexOptions.IgnoreCase Or RegexOptions.Singleline) Dim matchesFound As MatchCollection = SourceHTML.Matches(GETHTMLResponse)
I am using a string builder to set up an html table row by row so that it can be emailed. I currently gather my information from the database using a data reader and while dataReader.read, I use stringbuilder.Append to add each cell value to the table.The issue is that after about 200 rows, the html breaks and displays a cell value above the table in the email. I have tried changing the cell padding, but this was not successful.
I would like to print an HTML file that I am generating myself, but I want the pages to have the same table header at the start of each page. I think the best options to print an HTML file is the webbrowser control? but this won't give the table header at the start of each page (and I will have to contend with the ugly file://c:empfile.htm at the top of each page etc)
I have text stored in SQL as HTML. I'm not guaranteed that this data is well-formed, as users can copy/paste from anywhere into the editor control I'm using, or manually edit the HTML that's generated. The question is: what's the best way of going about removing or somehow ignoring <script/> and <form/> tags so that, when the user's text is displayed elsewhere in the Web Application, it doesn't disrupt the normal operation of the containing page.I've toyed with the idea of simply doing a "Find and Replace" for <script>/<form>with <div> (obviously taking into account whitespace and closing tags, if they exist). I'm also open to any way to somehow "ignore" certain tags. For all I know, there could be some built-in way of saying (in HTML, CSS, or JavaScript) "for all elements in <div id="MyContent">, treat <form> and <script> as <div>.
I am using ASP.NET 2.0 and SQL Server 2005. I am saving a value/string in the database <P>Test 1</P><P>Test2</P>
Now i want to decode/remove the html tags and display it properly to the user such as...

I am setting the value to a Text box where the TEXTMODE property of the text box is set to MULITILINE for scroll. Setting it to a normal Label work but not for my text box.......
I have a data table whose one column is related to a column of another table. I have a listbox in a form which shows a column (which is sorted by another column value by ORDER clause) of the parent table and other columns are in textboxes. The child table is represented by a datagrid. When I add a new item in parent table and click save, the newly created item is listed at the bottom of the listbox violating my ORDER clause. When I wrote some codes to fill data again after updating, it shows an error message[code]...
I have Dataset ds filled up with values Until now I was displaying values in GridView. Now I want that all the rows should be columns and columns should be rows.I have 2 options: Either 1 I can directly convert grid to columns and display it, or 2 I can convert the GridView to html and then write loops to convert. I was trying the 2nd option but I cant figure out how I should do that.[code]With this code I am still getting same as GridView. Please help me for converting rows to columns and vice versa.
I would like extract the data elements from tables within HTML pages.The output should produce an XML file.What is the best way to do that? I am using VB.NET 3.5.
I'm using the HtmlAgilityPack to extract data from a html document. I can get the data to display in console.Writeline however I need to get it into a DataGrid/DataTable so I can import it into SQL Server. For the life of me I can't figure out how to get it into the DataGrid.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim ds As New DataSet
I have a page with a html table on and am accessing it from code behind and changing what is displayed depending on values from a database, I have managed to change what text is displayed and the background color but i'm struggling to change either a rows or a cells font/fore color.
'Iterate through the rows of the table. For i = 0 To Table1.Rows.Count - 1 'Iterate through the cells of a row. For j = 0 To Table1.Rows(i).Cells.Count - 1
I am trying to write a class to serialize/deserialize something as simple as:
<table border="1"> <tr> <td>row 1, cell 1</td>
[Code]....
I just can't get it to serialize to this thing. I tried to generate the class using xsd but that produced a lot of garbage code and I really would like to maintain this by hand as it is easier than the monstrosity that xsd produced which didn't work anyway.
I'm wanting to extract a table on a regular basis from an HTML web page in to a listview control. Before I start the long winded manual process (which I'm sure I can do, finding strings etc). I was wondering if there was a built-in way with VB.NET?
I'm currently creating a HTML editor using a WebBrowser control and using IHTMLDocument2, but I'm currently having a problem that when I insert a table the user is unable to resize the table columns by dragging the border.
I was wondering whether anyone had done anything similar using IHTMLDocument2 and how I would be able to allow for the user to resize the tables like that. Or if anyone knows any good HTML editors that are written in VB.Net and are open source, unfortunately this is a requirement as I have to do some custom stuff for my customer.
if there is a way to make a html table from a datagridview? what im trying to do is enter details ( the rota at work) into my application and then export as html table and upload it to my site for all my staff to read so they have no excuse that they didnt know what time they had to be at work..... now i have tryed the "libs" i have found online but they give you no room to edit the sounding html page and just exports the datagridview into a html page
ps: i ahve the datagridview in my app and i have all the uploading code done only thing that is left is to some how convert the gid to html table
My question is a combination of VB.Net creating html code..No Google links to pointless areticles in languages that are not VB.NET, please. If you cannot code it yourself, please don't reply because it's so annoying to ask a question then get pointless, timewasting links just so you can get your points score up.I have a table which has 3 columns - nothing special just simple but its's the row number I am having issues with. Will explain soon.There is a directory with jpg files in it and the number of jpg files increased yesterday by 67, today by 37. Because the picture files come with any filename I have created a Windows app that renames the new files taking the ending point of yesterdays number as the starting point for today..So, each row holds 3 jpg files therefore 67 jpg / 3 = rows (yesterday). First number today is 68. I type 68 into the app I created, enumberating & moving (renaming) the jpg ('hduyhdgu.jpg becomes 68.jpg, suhdos.jpg becomes 69.jpg and so on for each of the new jpgs in that directory. That is done by the simple FileInfo/DirectoryInfo classes. Whilst renaming the photos in numerical sequence it has to write the html in the following form: [code] My Questions are:
1) How to sort out the row numbers so they flow in groups of 3 correctly and not 70, 71, 72, 71, 72, 73, 74, 75..?
2) How to create the table in code that dynamically draws itself with 3 columns (200px each done by CSS) wide and enough rown to hold every jpg in that directory? So, if I moved 5000 jpgs in that directory tomorrow the code will loop through and create the html.
3) If creating the table dynamically as in Q2 above how would I fix the place to draw it? Placeholder? A div is easy (<div 'id="MyTable" runat="server"></div>. In code behind: MyTable.InnerText=.../MyTable.InnerHtml=...) but is it the best idea? [code]
I would like to retrieve a value ( in this case: windspeed) from a HTML webpage the has table with the desired value contained it and put this value into a label within windows app form. Below is this HTML Data from the webpage.Ultitmately I would like to refresh the value every 30 secs
HTML <html> <meta http-equiv="refresh" content="30" /> <head>
again after a week of trying to figure out how to parse a HTML table I have yet to figure it out.Below is the Table I am trying to get the information out of.
[Code]...
The problem I am having is that It pulls out the 28,900 fine but I need to pull the rest of the information IE the 23,132 and the 170,000 and they will get placed into other Labels. Now they are not Static numbers they change all the time to higher or lower lumbers.
I have a html string like this:[code]I wish to strip all html tags so that the resulting string becomes:From another post here at SO I've come up with this function (which uses the Html Agility Pack):[code]
I have a DataGridView that is bound to a DataSet and I allow someone to remove a row from the table and I remove the row from the set. My code looks like this:
My problem I found is if the grid gets sorted the index of the rows no longer corresponds to the indexes in the DataSet. As a result the wrong rows get removed from the set.
Can I solve this problem with maybe having to sort the DataSet on some sort event of the DataGridView?
