如何将xml文档对象转换为字符串? [英] how to convert xml document object to string?

问题描述

我有一个字符串形式的 xml.我想更改其中的一些属性.
所以我所做的是

var xml//包含xml解析器 = 新的 DOMParser()xmlDoc = parser.parseFromString(xml, "text/xml")xmlDoc.setAttribute("名称", "随机")

现在 xmlDoc 具有所需的更改.但是如何再次获取xml的字符串表示呢?

解决方案

您需要在进行更改后将 xmlDoc 序列化回 XML:

var s = new XMLSerializer();var newXmlStr = s.serializeToString(xmlDoc);

现在你可以对更新后的 XML 字符串做你需要做的事情，覆盖你的 xml 变量，或者将它发送到服务器，或者其他任何......

请参阅 MDN 文档了解更多信息>

I have xml that I have in a string. I want to change some attributes in it.
So what I have done is

var xml //contains xml  
parser = new DOMParser()
xmlDoc = parser.parseFromString(xml, "text/xml")
xmlDoc.setAttribute("name", "random")

Now the xmlDoc has the required changes. But how do I get the string representation of the xml again?

解决方案

You will need to serialize your xmlDoc back to XML once you have made the changes:

var s = new XMLSerializer();
var newXmlStr = s.serializeToString(xmlDoc);

Now you can do what you need to do with the string of updated XML, overwrite your xml variable, or send it to the server, or whatever...
