Method readUntil

xmlparser/decoder.go:742–764

readUntil reads bytes to the buffer until the specified delimiter byte is encountered. The delimiter byte is included in the buffer. If an error occurs, it sets d.err and returns false.

(delim byte)

// The delimiter byte is included in the buffer.
// If an error occurs, it sets d.err and returns false.
func (d *Decoder) readUntil(delim byte) bool {
	for {
		b, err := d.r.ReadSlice(delim)
		if err != nil && !errors.Is(err, bufio.ErrBufferFull) && !errors.Is(err, io.EOF) {
			d.err = err
			return false
		}

		d.buf.Write(b)
		d.countNewLines(b)

		if err == nil {
			// We've read up to the delimiter byte, break the loop.
			return true
		}

		if err == io.EOF {
			// Reached EOF without finding the delimiter.
			d.err = err
			return false
		}
	}
