Oh, there are many. This phenomenon is not unique to the XML
family of languages. I would go so far as to say it is the norm.
Example 1: Regular expressions in the Python programming language
s = r"\s\tWord" prog = re.compile(s)
From the Python language point of view, s has a character string
value. It turns out that this value is an expression in a
different language, the Python regular expression language. (This
particular regular expression is very simple. It has no repetition
operators like '*' or '+'.) Read more about Python and regular
expressions at my answer

Overflow question, What exactly is a "raw string regex" and
how can you use it?
Example 2: Human-readable text in just about any language
s = "This is human-readable text"
This expression is a valid in many different programming
languages. s has a character string value. It turns out that this
value is an expression in a different language, the English
language.
