格式化XMLSerializer（）。serializeToString中的输出字符串

Question

我正在使用以下调用来获取部分DOM的XML代码。

var sXML = new XMLSerializer().serializeToString(document.getElementsByTagName("TopElementTag")[0]);

但是，当我显示这个字符串时，它就是一行。

有没有办法格式化这个字符串，以便它有换行符和标签，使其易于阅读？

Answer 1

我使用以下代码vkBeutify。

var sXML = new XMLSerializer().serializeToString(document.getElementsByTagName("TopElementTag")[0]);
sXML = vkbeautify.xml(sXML);

Answer 2

这个小型图书馆可以美化和缩小小于1kb的未压缩文件。
