我用它来使用一个XML文档

_getXmlDocument: function(TextToParse) {
try {
            //XmlDoc = new ActiveXObject("Microsoft.XMLDOM")
            var XmlDoc = new ActiveXObject("Msxml2.DOMDocument.6.0");
            XmlDoc.async = "false"
            XmlDoc.loadXML(TextToParse);
        }
        catch(ex) {
            Efficy.log("_getXmlDocument - Cannot create an XML document: " + ex.description)
            //Firefox, Mozilla, Opera, etc.
            try {
                Parser = new DOMParser()
                XmlDoc = Parser.parseFromString(TextToParse,"text/xml")
            }
            catch(ex) {throw new Error("Cannot create an XML document: " + ex.description)}
        }
        return XmlDoc
    }

我想在得到一个特定的标签后
privates._XmlGetElementsByTagName（data，“tagname”）
简单地导出原始XML，包括字符串中的XML标记。但是我找不到这样做的方法
我尝试循环等，但没有结果

使用XMLSerializer将其改回字符串。

const note = `<?xml version="1.0" encoding="UTF-8"?>
<note>
  <to>Tove</to>
  <from>Jani</from>
  <heading>Reminder</heading>
  <body>
    <para>Bacon ipsum dolor amet tail chuck beef, biltong capicola pork belly jowl tongue meatloaf brisket beef ribs picanha.

</note>
`

const parser = new DOMParser()
const xmlDoc = parser.parseFromString(note,"text/xml");

const body = xmlDoc.querySelector("body");

const serializer = new XMLSerializer();
const xmlStr = serializer.serializeToString(body);

console.log(xmlStr);

您可以将特定的DOM节点序列化为XML。

const xmlString = `<foo><bar atttribute="value">content</bar></foo>`;
const xmlDocument = (new DOMParser).parseFromString(xmlString, 'text/xml');
const serializer = new XMLSerializer();

const output = Array.from(xmlDocument.getElementsByTagName('bar'))
  .map(
    (node) => serializer.serializeToString(node)
  )
  .join('');
  
console.log(output);

对于node.js，您可以使用@xmldom/xmldom。
