XML解析遍历子级别

Question

Currently I have XML in the following format:

 -<collection>
     -<beanRepresentation>
       <beanRepName>1</beanRepName>
       -<group>
        </group>
       -<relationships>
         <inputBeanId>1</inputBeanId>
         <outputBeanId>2</outputBeanId>
        </relationships>
       -<relationships>
         <inputBeanId>1</inputBeanId>
         <outputBeanId>3</outputBeanId>
        </relationships>
     </beanRepresentation>

     </beanRepresentation>
     <beanRepresentation>

   <collection>

I want to loop through each <beanRepresentation> 's and get the <outputBeanId> . Right now my code works when there is ONLY ONE <relationships> , but the above XML, has two <relationships> 's. and I need to go in and get BOTH of the <outputBeanId> 's so I can put them into my function connectPort() .

$(window).load(function(){  
        var $xml = $(xmlDoc);
        $xml.find('beanRepresentation').has('outputBeanId').has('inputBeanId').each(function () {
        var $br = $(this);
        connectPort($br.find('beanRepName').text(), $br.find('outputBeanId').text());
        })
    });

This only works when is there only one <relationships> , how do I add a loop in here so I can get N amount of <relationships> to work.

Answer 1

You can do something like below:

$xml.find('beanRepresentation').each(function() {
      $(this).find('relationships').has('outputBeanId').has('inputBeanId').each(function(){
      // Blah Blah
      });
});

Hope this Helps!!

Answer 2

You will have to make another loop for each relationship

$(window).load(function(){  
    var $xml = $(xmlDoc);
    $xml.find('beanRepresentation').each(function () {
       var $br = $(this),
           relations = $br.find('relationships').has('outputBeanId').has('inputBeanId'),
           beanName = $br.find('beanRepName').text();

       relations.each(function(){
          var outputId = $(this).find('outputBeanId').text();
          connectPort(beanName , outputId);
       });
    })
});
