xml.getelement by tag name无法正常工作

xml.getelement by tag name is not working properly

本文关键字：常工作 工作 by getelement tag name xml      更新时间：2023-10-07

我已经读取了字符串中的所有xml内容。现在我正在解析那个字符串。我解析ias的代码如下：

  parser=new DOMParser();
      xmlDoc=parser.parseFromString(output,"text/xml");//output is a string which contains xml
      var region= xmlDoc.getElementsByTagName("Region");
       console.log("Region lenght"+region.length);

有一个标签名称Regions，在我的xml字符串中有很多Regions。但我面临的问题是xmlDoc.getelementBytagName只返回1个元素。

我的xml字符串的代码段如下：

<?xml version="1.0"?>

JS

  parser=new DOMParser();
  xmlDoc=parser.parseFromString(output,"text/xml");//output is a string which contains xml
  var region= xmlDoc.getElementsByTagName("Regions"); // Regions
   console.log("Region length"+region.length);
