在xml中搜索屬性

我嘗試了許多不同的方法，但沒有運氣。我所要做的就是確定當前URL的域，並從基於域的XML文件中提取一個值。在xml中搜索屬性

任何幫助將非常感激。

merchants.xml

<?xml version="1.0" encoding="utf-8"?> 
<catalog> 
    <merchant id="1"> 
    <domain>http://www.amazon.com</domain> 
    <affiliate>1</affiliate> 
    </merchant> 
</catalog>

popup.js

function ReadXML() { 
    try { 
     var xmlPath = "merchants.xml"; 
     $.ajax({ 
      type: "GET", 
      url: xmlPath, 
      dataType: "xml", 
      success: parseXML 
     }); 
    } catch (e) { 
     alert("Error while reading XML; Description – " + e.description); 
    } 
} 

function parseXML(xml) { 
    var $merchant = $(xml).find('domain').filter(function() { 
     return $(this).text() == "http://www.amazon.com"; 
    }).closest('domain'); 
    var affiliate = $('affiliate', $domain).text(); 

    if(window.location.hostname.indexOf("http://www.amazon.com") > -1) { 
     document.getElementById("demo").innerHTML = affiliate; 
    } 
} 
readXML()

popup.html

<!doctype html> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
    <head> 
     <title>Test</title> 
     <style> 
      body { 
      font-family: "Segoe UI", "Lucida Grande", Tahoma, sans-serif; 
      font-size: 75%; 
      } 
      #status { 
      /* avoid an excessively wide status text */ 
      white-space: normal; 
      text-align: center; 
      width: 200px; 
      height: 225px; 
      overflow: hidden; 
      max-width: 400px; 
      word-wrap: normal; 
      } 
     </style> 
     <script type="text/javascript" src="popup.js"></script> 
     <script src="http://code.jquery.com/jquery-latest.js"></script> 
    </head> 
    <body> 
     <table id="demo"></table> 
     <div id="status"></div> 
    </body> 
</html>

您可以將XML轉換成JSON與jQuery XML to JSON Plugin。作爲結果，你會得到一個JavaScript對象的所有屬性：

{"merchant":{"domain":"http://www.amazon.com","affiliate":"1","id":"1"}}

完整的示例：

<script type="text/javascript" src="https://code.jquery.com/jquery-2.2.3.min.js"></script> 
<script type="text/javascript" src="https://jquery-xml2json-plugin.googlecode.com/svn/trunk/jquery.xml2json.js"></script> 
<script type="text/javascript"> 
    $(function() { 

     var 
      xml, 
      json; 

     xml = 

      '<?xml version="1.0" encoding="utf-8"?>' + 
      '<catalog>' + 
       '<merchant id="1">' + 
       '<domain>http://www.amazon.com</domain>' + 
       '<affiliate>1</affiliate>' + 
       '</merchant>' + 
      '</catalog>'; 

     json = $.xml2json(xml); 

     alert(json.merchant.domain); 
    }); 
</script>

var affiliateData = {}; 

function loadUrlData(url, data, affiliateData) { 
    var urlDomain = url.substring(url.indexOf('//') + 2); 
    if (urlDomain.indexOf('/') > -1) { 
    urlDomain = urlDomain.substring(0, urlDomain.indexOf('/')); 
    } 
    if (urlDomain.indexOf('?') > -1) { 
    urlDomain = urlDomain.substring(0, urlDomain.indexOf('?')); 
    } 

    lastIndexOfDot = urlDomain.lastIndexOf('.'); 
    if (lastIndexOfDot < 0) { 
    return; 
    } 


    do { 
    affiliateData[urlDomain] = data; 
    urlDomain = urlDomain.slice(urlDomain.indexOf('.') + 1); 
    } while (urlDomain.indexOf('.') > -1); 
}; 
function getAffiliateData(url, affiliateData) { 
    var urlDomain = url.substring(url.indexOf('//') + 2); 
    if (urlDomain.indexOf('/') > -1) { 
    urlDomain = urlDomain.substring(0, urlDomain.indexOf('/')); 
    } 
    if (urlDomain.indexOf('?') > -1) { 
    urlDomain = urlDomain.substring(0, urlDomain.indexOf('?')); 
    } 

    lastIndexOfDot = urlDomain.lastIndexOf('.'); 
    if (lastIndexOfDot < 0) { 
    return 'none'; 
    } 
    do { 
    for (domain in affiliateData) { 
     if (domain == urlDomain) { 
     return affiliateData[domain]; 
     } 
    } 
    urlDomain = urlDomain.slice(urlDomain.indexOf('.') + 1); 
    } while (urlDomain.indexOf('.') > -1); 

    return 'none'; 
}; 

var url = 'http://www.amazon.com?asdf=/a/b/c'; 
var url2 = 'http://www.yahoo.com?asdf=/a/b/c'; 

loadUrlData('http://www.amazon.com?asdf=/a/b/c', 'data amazon', affiliateData); 
loadUrlData('http://www.yahoo.com?asdf=/a/b/c', 'data yahoo', affiliateData); 

alert(getAffiliateData(url, affiliateData)); 
alert(getAffiliateData(url2, affiliateData));
