Summary of JQuery's methods for parsing XML_jquery

The examples in this article summarize the method of JQuery parsing XML. Share it with everyone for your reference, the details are as follows:

Using JavaScript to parse XML data is a common programming task. If JavaScript can do it, JQuery can certainly do it. Let's summarize some examples of using JQuery to parse XML.

The first option:

<script type="text/javascript">
$(document).ready(function() {
  $.ajax({
     url: 'http://localhost/cgi/test.xml',
     dataType: 'xml',
     success: function(data){
       //console.log(data);
       $(data).find("channel").find("item").each(function(index, ele) {
        var titles = $(ele).find("title").text();
        var links = $(ele).find("link").text();
        console.log(titles+'-----');
        $("#noticecon").find('ol').append('<li><a href="'+links+'">'+titles+'</a></li>');
      });
    }
  });
})
</script>
<div id="noticecon">
  <ol>
  </ol>
</div>

Second option:

<script type="text/javascript">
  $.get("http://localhost/cgi/test.xml", function(data){
    $(data).find('channel').find('item').each(function(index, ele){
      var titles = $(ele).find('title').text();
      var links = $(ele).find('link').text();
      $("#noticecon").find('ol').append('<li><a href="'+links+'">'+titles+'</a></li>');
    })
  });
</script>
<div id="noticecon">
  <ol>
  </ol>
</div>

The general steps are as follows:

1. Read xml file

$.get("xmlfile.xml",function(xml){
  //xml即为可以读取使用的内容，具体读取见第2点
});

2. Read xml content

If the xml read comes from an xml file, combined with the above point, the processing is as follows:

$.get("xmlfile.xml",function(xml){ 
  $(xml).find("item").length; 
});

If you are reading an xml string, please note that the xml string must be surrounded by "" and "" before it can be parsed

$("<xml><root><item></item></root></xml>").find("item").length;

Parse xml content:

Sample xml:

<&#63;xml version="1.0" encoding="utf-8" &#63;>
<fields>
 <field Name="Name1">
 <fieldname>dsname</fieldname>
 <datatype>字符</datatype>
 </field>
 <field Name="Name2">
 <fieldname>dstype</fieldname>
 <datatype>字符</datatype>
 </field>
</fields>

The following is the parsing sample code:

$(xml).find("field").each(function() {
  var field = $(this);
  var fName = field.attr("Name");//读取节点属性
  var dataType = field.find("datatype").text();//读取子节点的值
});
