Also, note that the about: However, due to legacy constraints, it has gained another very important purpose:

If you are using it before the onload event fires, as you presumably are, to build elements from structured data for instance, it is the appropriate tool to use. By the time it is finished this script creates over DOM nodes, mostly table cells.

On a 7 year old PC running Firefox on Vista, this little exercise takes less than 2 seconds using document. The page just pops into existence fully formed, ready to handle events. Using insertAdjacentHTML is not a direct substitute as the browser closes tags which the script requires remain open, and takes twice as long to ultimately create a mangled page.

Writing all the pieces to a string and then passing it to insertAdjacentHTML takes even longer, but at least you get the page as designed.

Other options like manually re-building the DOM one node at a time are so ridiculous that I'm not even going there. The fact that it is one of the oldest methods in JavaScript is not a point against it, but a point in its favor - it is highly optimized code which does exactly what it was intended to do and has been doing since its inception.

It's nice to know that there are alternative post-load methods available, but it must be understood that these are intended for a different purpose entirely; namely modifying the DOM after it has been created and memory allocated to it.

It is inherently more resource-intensive to use these methods if your script is intended to write the HTML from which the browser creates the DOM in the first place.

Just write it and let the browser and interpreter do the work. That's what they are there for. I just tested using an onload param in the body tag and even at this point the document is still open and document.

Also, there is no perceivable performance difference between the various methods in the latest version of Firefox.

It may make a difference on a cheap smartphone though.Nov 25,  · Introduction. When looking at XSS (Cross-Site Scripting), there are three generally recognized forms of XSS. Reflected, Stored, and DOM Based XSS Prevention Cheatsheet does an excellent job of addressing Reflected and Stored XSS.

This cheatsheet addresses DOM (Document Object Model) based XSS and is an extension (and assumes comprehension of) the XSS Prevention .

CDATA sections in XML. In an XML document or external parsed entity, a CDATA section is a section of element content that is marked for the parser to interpret purely as textual data, not as markup.

A CDATA section is merely an alternative syntax for expressing character data; there is no semantic difference between character data that manifests as a CDATA . For those who don't want to use HTML agility pack and want to get HtmlDocument from string using code only here is a good article on how to convert string to HtmlDocument.
