Question

我正在尝试使用xml2js构建XML节点。当我添加用cdata包装的html标签时，它会创建一个单独的节点，如下所示。如果我将CDATA包装在“＆lt;＆gt;”中里面的值是未定义的。基本上我正在尝试创建XML文档，我可以从中获取节点值并使用jQuery / Angular在HTML文档中显示它。那些节点必须能够包含HTML标签

var xml2js = require('xml2js');

var parser = new xml2js.Parser({
    explicitArray: false
});
var builder = new xml2js.Builder({
    cdata: true
});


var test = "<parent>![CDATA[Hey There! <span> Buddy.</span>]]</parent>"

parser.parseString(test, function(err, result) {
    var xml = builder.buildObject(result)
    console.log(xml)
});
//Output
/*
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<parent>
  ![CDATA[Hey There! ]]
  <span> Buddy.</span>
</parent>
*/


var test2 = "<parent><![CDATA['Hey There! <span> Buddy.</span>']]></parent>";

parser.parseString(test, function(err, result) {
    var xml = builder.buildObject(result)
    console.log(xml)
});
//Output : 
/*
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<parent><![CDATA[undefined]]></parent>
*/

Answer 1

您的首次测试几乎正确无误。你真的需要＆lt; ＆GT; CDATA内容周围的符号。

此代码：

var xml2js = require('xml2js');

var parser = new xml2js.Parser({
    explicitArray: false
});
var builder = new xml2js.Builder({
    cdata: true
});

var test = "<parent><![CDATA[Hey There! <span> Buddy.</span>]]></parent>";

parser.parseString(test, function(err, result) {
    var xml = builder.buildObject(result);
    console.log(xml);
});

生成此输出：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<parent><![CDATA[Hey There! <span> Buddy.</span>]]></parent>

它可以在没有解析器的情况下进行。 _有助于处理标签内的内部文本。

const xml2js = require('xml2js');

const builder = new xml2js.Builder({
    cdata: true
});

const test = "Hey There! <span> Buddy.</span>";

const xml = builder.buildObject({
   parent: {
     _: test,
   }
});

console.log(xml);

如何在xml2js xml的CDATA中添加html标签？
