How to read in a block

[suntong]

The Example (15b)
https://godoc.org/github.com/spakin/awk#ex-package--15b

shows how to deal with lines between occurrences of the strings "start" and "stop" (AWK: /start/, /stop/).

My question is, how to define the awk.Script func so that it will process the lines between "start" and "stop" as a block? -- My "start" and "stop" case is "<table>" and "</table>", and I got the error of invalid XML format, and I believe I'm reading them one line at a time, instead of all the lines between "<table>" and "</table>" as a block.

Please help. Thanks.

One possibility is to buffer all the lines between <table> and </table> and process the buffer later on, as in the following example:

package main

import (
	"fmt"
	"github.com/spakin/awk"
	"os"
)

func main() {
	s := awk.NewScript()
	s.State = make([]byte, 0)
	s.AppendStmt(awk.Auto("<table>", "</table>"), func(s *awk.Script) {
		str := []byte(s.F(0).String() + "\n")
		s.State = append(s.State.([]byte), str...)
		if s.F(0).Match("</table>") {
			s.Println("=== I HAVE A TABLE ===")
			fmt.Print(string(s.State.([]byte)))
			s.Println("=== ALL DONE ===")
			s.State = make([]byte, 0)
		}
	})
	s.Run(os.Stdin)
}
