Latex: access the content of an environment while using \newenvironment

Question

Hey guys,

I'm trying to make my own environment with \newenvironment.

Is it somehow possible to access the "body" of the environment?

For example if the user uses

\begin{myenv}
    i'm the content
\end{myenv}

i want to analyze the "i'm the content" in the definition of the environment.

Thanks in advance,

Use package 'environ'.

\NewEnviron{myenv}{\colorbox[gray]{0.7}{\BODY}} 

where \BODY is a your "body".
