Question

很难，我设法实现了一个允许我搜索xml文件的功能。但是，它似乎只是将文件的最后<item>的数据返回到屏幕。

例如，当搜索特朗普的关键词（对不起）时，它将返回与特朗普有关的文章（这是最后一个item）。但是，还有另一个item与文件中的特朗普（第一项）有关，但未被退回。

我的假设是，这是任何简单的解决方法，但我正在努力。任何朝着正确方向的点头都会非常感激。

HTML

<form action="" class="search-form"> Search
      <br>
      <br>
      <div class="form-group has-feedback">
        <label for="search" class="sr-only">Search</label>
        <input type="text" class="form-control" name="search" id="search" placeholder="Search for current topics, e.g., Brexit"><span class="glyphicon glyphicon-search form-control-feedback"></span>
      </div>
    <br>
  </div>
  <div class="col-md-5 col-md-offset-1">
    <br>
    <div id="search_output"> Search results will appear here.</div>

的jQuery

    $(document).ready(function(){
    $('#search').on('keyup', function(){
        $.ajax({
            type: "GET",
            url: "top_news.xml",
            dataType: "xml",
            success: parseXML
        });
    });
});
function parseXML(xml){
    var searchFor = $('#search').val();
    var reg = new RegExp(searchFor, "i");
    $(xml).find('item').each(function(){
        var title = $(this).find('title').text();
        var titleSearch = title.search(reg);
        var desc = $(this).find('description').text();
        var descSearch = desc.search(reg);
        $('#search_output').empty();
        if(titleSearch > -1){
            $('#search_output').append('Found <i>'+searchFor+'<\/i> in title: '+title.replace(reg, '<b>'+searchFor+'</b>')+'<br \/>');
        }
        if(descSearch > -1){
            $('#search_output').append('Found <i>'+searchFor+'<\/i> in description: '+desc.replace(reg, '<b>'+searchFor+'</b>')+'<br \/>');
        }
    });    
}
