XMLBuilder将属性添加到XML文件中的错误节点

Question

我正在使用XMLBuilder包在Node.js中创建XML文件。除了一件事，一切都很好。我试图向root元素添加属性，但由于某种原因，它被添加到child元素中。

我已经这样声明了我的root元素：

//Create the header for XML
var builder     =   require('xmlbuilder');
var root        =   builder.create('test:XMLDocument')
root.att('schemaVersion', "2.0")
root.att('creationDate', '2020-10-09T09:53:00.000+02:00')
root.att('xmlns:xsi', "http://www.w3.org/2001/XMLSchema-instance")
root            =   root.ele('MyBody')
root            =   root.ele('MyEvents')

在声明之后，当我试图向我的根元素添加更多属性时：

root.att('new1','additionalAttributes1')
root.att('new2','additionalAttributes2')

它被附加到MyEvents上，看起来像这样：

<?xml version="1.0"?>
<test:XMLDocument schemaVersion="2.0" creationDate="2020-10-09T09:53:00.000+02:00">
<MyBody>
<MyEvents new1="additionalAttributes1" new2="additionalAttributes2">
</MyEvents>
</MyBody>
</test:XMLDocument>

但我希望生成的XML文件显示如下：

<?xml version="1.0"?>
<test:XMLDocument schemaVersion="2.0" creationDate="2020-10-09T09:53:00.000+02:00" new1="additionalAttributes1" new2="additionalAttributes2">
<MyBody>
<MyEvents>
</MyEvents>
</MyBody>
</test:XMLDocument>

我知道，如果我像这样声明我的XML元素，那么我能够实现预期的结果，但由于我将其传递给另一个函数，我无法像这样声明它：

//Create the header for XML
var builder             =   require('xmlbuilder');
var root        =   builder.create('test:XMLDocument')
root.att('schemaVersion', "2.0")
root.att('creationDate', '2020-10-09T09:53:00.000+02:00')
root.att('xmlns:xsi', "http://www.w3.org/2001/XMLSchema-instance")

root.att('new1','additionalAttributes1')
root.att('new2','additionalAttributes2')
root            =   root.ele('MyBody')
root            =   root.ele('MyEvents')

我试着添加.up((，看看它是否被添加到父对象中，但没有成功。有人能帮我吗？当我有多个孩子时，我如何将属性添加到父母身上并达到所需的结果？

Answer 1

你只需要上升两次

var builder = require('xmlbuilder')
var root = builder.create('test:XMLDocument')
root.att('schemaVersion', '2.0')
root.att('creationDate', '2020-10-09T09:53:00.000+02:00')
root.att('xmlns:xsi', 'http://www.w3.org/2001/XMLSchema-instance')
root = root.ele('MyBody')
root = root.ele('MyEvents')
root = root.up().up()
root.att('new1','additionalAttributes1')
root.att('new2','additionalAttributes2')
console.log(root.end({pretty: true}));

输出

<?xml version="1.0"?>
<test:XMLDocument schemaVersion="2.0" creationDate="2020-10-09T09:53:00.000+02:00" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" new1="additionalAttributes1" new2="additionalAttributes2">
<MyBody>
<MyEvents/>
</MyBody>
</test:XMLDocument>
