要求未定义为xml2js

Question

我想使用库xml2js。我将它安装在带有npm的项目文件夹中。

var parseString = require('xml2js').parseString;
var xml = "<root>Hello xml2js!</root>";
parseString.(xml, function (err, result) {
    console.dir(result);
});

执行节点myfile.js时出错：

d:\Profiles\user\ProjectIDE\Aproject\parseXML.js:3
parseString.(xml, function (err, result) {
            ^

SyntaxError: Unexpected token (

Answer 1

语法错误：

而不是这样：

parseString.(xml, function (err, result) {
    console.dir(result);
});

试试这个：

parseString(xml, function (err, result) {
    console.dir(result);
});

Answer 2

这对我起了作用：

    var xml2js = require('xml2js');
    var parser = new xml2js.Parser();
    // var util = require('util');

    parser.parseString(xml, function(err, result){
      console.log(result);
      // In case you want to see the whole thing.
      // console.log(util.inspect(result, {showHidden:true, depth:null}); 
    });
