How do I escape this ampersand in the source XML? I tried &, but this is decoded as the actual ampersand character (&), which is invalid in HTML. So I want to escape it in such a way that it will be rendered as & in the web page that uses the XML output.
HTML Character Entities Some characters are reserved in HTML. If you use the less than (<) or greater than (>) signs in your HTML text, the browser might mix them with tags. Entity names or entity numbers can be used to display reserved HTML characters. Entity names look like this:
An explanation of when to use encoded ampersands (&) in HTML and Javascript and when not to encode them.
What is & is the first place? Because one symbol can mean different things in coding (in general), so there needs to be a way to differentiate one kind from another.
The ampersand is no exception. Here's an example of what is required in order to display the code required to output an ampersand symbol. Note that the amp; bit needs to be included twice. Without including it twice, a single ampersand symbol would rendered and that's all.
In SGML, XML, and HTML, the ampersand is used to introduce an SGML entity, such as (for non-breaking space) or α (for the Greek letter α). The HTML and XML encoding for the ampersand character is the entity &. 40 This can create a problem known as delimiter collision when converting text into one of these markup languages.
From w3c: Authors should use & (ASCII decimal 38) instead of "&" to avoid confusion with the beginning of a character reference (entity reference open delimiter).
Note that I've edited your first post to have it shown the entity code "&" -> "&"
The thread title doesn't resolve the entity code and displays them as such.
I understand the rationale behind why most of the HTML character Entities were created, but I don't understand the purpose behind the ampersand HTML entity. & contains more bits than a &
