How To Ouptput doc worddocuemt sector?

[xlcoder]

as you code

if entry.Name == "WordDocument" {
	fmt.Println(buf[:i])
        fmt.Println(string(buf[:i]))
}

will output unknow code ,

I expect output person read string or text

Ok, same issue now..

To get the bytes out of that stream you could do something like this:

package main

import (
"io"
"io/ioutil"
"log"
"os"

"github.com/richardlehane/mscfb"

)

func main() {
file, err := os.Open("test/test.doc")
defer file.Close()
if err != nil {
log.Fatal(err)
}
doc, err := mscfb.New(file)
if err != nil {
log.Fatal(err)
}
for entry, err := doc.Next(); err == nil; entry, err = doc.Next() {
if entry.Name == "WordDocument" {
buf, err := ioutil.ReadAll(entry)
if err != nil {
log.Fatal(err)
}
fmt.Println(string(buf))
}
}
}

BUT

"... [this] package only implements the MS-CFB spec (https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-cfb/53989ce4-7b05-4f8d-829b-d08d6148375b) which is a common container format used by a lot of different Windows software. It doesn't implement the MS Word spec (MS-DOC) - so can't help you identify byte ranges of the runs of text in a word doc. To do something like that, you'd need to look at the MS-DOC spec (https://docs.microsoft.com/en-us/openspecs/office_file_formats/ms-doc/d7fae142-670d-4cd5-869a-708366984a71) - you'd probably need to work out how to interpret the File Information Block structure (FIB) at the start of the WordDocument stream to get offsets for where the text entries are in the stream. That's probably quite a bit of work. The other option might be just to iterate over the byte slice and delete any bytes not in the ASCII range (this won't work if the doc stream has UTF16 or some other encoding)? e.g.

buf2 := make([]byte, 0, len(buf))
for _, c := range buf {
if c > 6 && c < 128 {
buf2 = append(buf2, c)
}"
