Removing all attributes from a table

Removing all attributes from a table

244 Views Asked by Deantjee__ At 27 October 2025 at 12:37

I want to have a standard table without any attributes. But I have got a table that's exported from a program called QlikView in there they automatically give the table attributes, weirdly too. Is there a fast way to remove all these attributes, I'm using .NET Core and I haven't found any. I want to do this so that I can use my own CSS easily. Here is the HTML I'm getting when exporting:

<HTML>
<HEAD>
<META CONTENT="StraightTableBox">
<TITLE>TM_SW_0004 Resultaten overzicht dekweken</TITLE>
<SCRIPT> function UpdateImage(name) { var img = document.getElementById(name); var url = '' + document.location; url = url.substr(0, url.lastIndexOf('/')+1); img.src = url + name; }</SCRIPT></HEAD>
<BODY CLASS="std" BGCOLOR="#FFFFFF" TEXT="#000000">
<!--StartFragment-->

<TABLE style="font-size:9pt;"  border="1" bordercolor="#C0C0C0"  CELLSPACING=0  CELLPADDING=2 bgcolor="#ffffff">

If all you want is to remove attributes on the table (not any children) then

var table = document.QuerySelector("table");
var attributes = table.Attributes.Select(m => m.Name).ToArray();

foreach (var attr in attributes)
{
    table.RemoveAttribute(attr);
}

If you also want to get all the children and remove their attributes, then I'd say using table.QuerySelectorAll("*") for getting all descendants + applying the same code as above with the RemoveAttribute would do the job.
