[erlang-questions] What is "Rest" in the return of xmerl_scan:string() ?

[达曾]

Hi all,
  I am using xmerl_scan to decode a xml string, but when calling
xmerl_scan:sting, it returns in a tuple:

{xmlElement{}, Rest}

I've searched about this API, looks like we all ignore the Rest in return.

So what is the Rest used for?? Should I ignore them??

Here is the defination of  xmerl_scan:string/1 in erlang OTP 19,

*string(Text::list()) -> {**xmlElement()**, Rest}*


 Great thanks.
