jquery - 使用 Javascript 或 JQuery 按元素值检索 XML 节点

Question

我正在处理一个问题，我需要按特定属性值过滤 XML 文档并检索所有匹配的节点。但是，我没有得到想要的结果。

这是我用来遍历两个单独的 XML 文档的 jQuery。为了简单起见，现在我正在对 definitionId 进行硬编码。然后我需要按 definitionId 过滤 instanceData XML 文档并返回所有符合该条件的节点。

$(definitionData).find("Entity").each(function (index) {
    var definitionId ="b1df0728-d761-e311-84c5-6c3be5a8bcd8";

    var instanceXmlRecords = $cm(instanceData).find("Entity").each(function () {
    if ($(this).find("Id").text() == definitionId) {
        return this;
    }
});
}

Answer 1

您必须首先将 xml 字符串转换为 xml 文档，然后您可以通过标签名称在该文档中进行搜索。离开命名空间。

http://jsfiddle.net/2D9MB/

var xml = $("#xml").text();
var xmlDoc = $.parseXML(xml);
var definitionId ="b1df0728-d761-e311-84c5-6c3be5a8bcd8";
// find all entities that have an Id that contains the definitionId
var entities = $(xmlDoc).find("Entity:has(Id:contains(" + definitionId + "))");
console.log(entities); // one entity

您甚至可以将最后一行缩短为:

var entities = $(xmlDoc).find("Entity:contains(" + definitionId + ")");
