A MHTML(.mht) file parser.
Only tested in .mht converted by Word 2016.
npm install mhtml-parser --savelet parser = require('mhtml-parser');
parser.loadFile(__dirname + "/simple/simple.mht", {
charset: "gbk"
}, function(err, data) {
if (err) throw err;
console.log(data);
});let parser = require('mhtml-parser');
let fs = require("fs");
let fileName = 'image001.jpg';
parser.loadFile(__dirname + "/simple/simple.mht", {
charset: "gbk",
readMode: parser.constants.READ_MODE_POSITION
}, function(err, data) {
if (err) throw err;
fs.open(__dirname + "/test/simple/simple.mht", "r", function(err, fd) {
let buffer = new Buffer(data[fileName].bufferLength);
fs.readSync(fd, buffer, 0, data[fileName].bufferLength, data[fileName].startPosition);
console.log(buffer.toString());
});
});let parser = require('mhtml-parser');
let data = parser.parse(iconv.decode(require("fs").readFileSync(__dirname + "/simple/simple.mht", null), "gbk"), {});In this mode, option.readMode will always be constants.READ_MODE_ALL.
Default Value: utf-8
To convert binary data to detected charset. Useless when readMode == READ_MODE_POSITION.
Default Value: false
To decode quoted-printable data, which is something like <a href=3D\"http://zsxsoft.com\">. Useless when readMode == READ_MODE_POSITION.
See here: https://github.com/mathiasbynens/quoted-printable
Default Value: constants.READ_MODE_ALL
Avaiable items list here:
- READ_MODE_ALL - Read the whole file to the memory. You can directly get each file's content from
data.fileName.data - READ_MODE_POSITION - Scan the whole file and only get the position and length of each file but not reading them.
