how to get tags content by grep
1) Is it possible to get tags content by grep -E ? For example title. Source text "<title>My page<title>"; to print "My page".

2) which bash utility to use when I want to use regex in this format?
(?<=title>).*(?=</title)

_________________________________________________________________

DESCRIPTION

       These  routines	are used to generate complete responses, including headers, status codes, content types, and the requested data.  They all
       return a status code which is NS_OK if the response was sent or NS_ERROR if an underlying call to sent the content failed.

       int Ns_ConnReturnAdminNotice(conn, status, title, msg)
	      This routine is equivalent to Ns_ConnReturnNotice. In prior versions, it would format a slightly different response which was  later
	      considered inconsequential.

       int Ns_ConnReturnData(conn, status, data, len, type)
	      Generates  a reponse with the given HTTP status including a content-type header with the given type.  Content pointed to by the data
	      argument of length len is then sent without any modification via an underlying call to Ns_ConnFlushDirect.

       int Ns_ConnReturnCharData(conn, status, data, len, type)
	      Generates a response as with Ns_ConnReturnData except that the given content pointed to by data is assumed to be a text stream which
	      is output encoded using the appropriate Tcl_Encoding based on the given type mimetype and possibly gzip compressed via an underlying
	      call to Ns_ConnFlush.

       int Ns_ConnReturnHtml(conn, status, msg, len)
	      This is equivalent to Ns_ConnReturnCharData(conn, status, msg, len, "text/html").

       int Ns_ConnReturnNotice(conn, status, title, msg)
	      Constructs a basic HTML response and sends it via Ns_ConnReturnHtml.  The title string is placed both in the <head> portion as  well
	      as  an  <h2>  tag in the <body> portion of the document.	If the title is NULL, it defaults to the string "Server Message".  The msg
	      string, if not NULL, follows the body and is copied unaltered.  This routine is useful for generating  very  basic  responses.   For
	      example, it is used by the various builtin reponse routines such as Ns_ConnReturnUnauthorized.
