Question

我需要一种方法来搜索XML String并返回一个包含＆＃34;记录＆＃34;的数组。符合多个搜索条件的元素。

结构如下：

  <record>
     <project_name>Deploy Document Management</project_name>
     <project_phase>Design</porject_phase>
     <status>Not Started</status>
     <priority>Medium</priority>
  </record>
  <record>
     <project_name>Do Something Else</project_name>
     <project_phase>Design</porject_phase>
     <status>Not Started</status>
     <priority>Medium</priority>   
  </record>

如果我想返回一组＆＃34;记录＆＃34;其中status =＆＃34;未开始＆＃34;和priority =＆＃34; Medium＆＃34; ....我将如何使用javascript或JQuery？

要清楚，我需要符合条件的每条记录的整个记录。

提前致谢。

一个良好的开端是解析XML，例如使用jQuery.parseXML()

然后，您可以像往常一样

访问返回文档的DOM

示例：

＆＃13;

var xml = '<xml><record><project_name>Deploy Document Management</project_name><project_phase>Design</project_phase><status>Not Started</status><priority>Medium</priority></record><record><project_name>Do Something Else</project_name><project_phase>Design</project_phase><status>Not Started</status><priority>Low</priority></record></xml>'

var xmlDoc = $.parseXML(xml)
var $xml = $(xmlDoc)
var $records = $xml.find("record").filter(function() {
  return $(this).find("status").text() == "Not Started" && 
    $(this).find("priority").text() == "Medium"
});

// $records already holds all Elements as an Array, but you cold get the texts like this:
var records = []
$records.each(function() {
  // do your thing
  records.push($(this).text())
})

document.write(JSON.stringify(records))

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

＆＃13;

请注意，您的原始XML project_phase

中存在拼写错误

在Javascript / JQuery中搜索XML字符串
