Question

我正在研究一个问题，我需要通过特定的属性值过滤XML文档并检索匹配的所有节点。但是，我没有得到理想的结果。

这是我用来遍历两个单独的XML文档的jQuery。现在我为了简单起见我正在硬编码一个definitionId。然后，我需要通过definitionId过滤instanceData XML文档，并返回符合该条件的所有节点。

$(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

您必须先将xml字符串转换为xml文档，然后才能通过标记名称在该文档中进行搜索。不要使用命名空间。

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

您甚至可以缩短最后一行：

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

使用Javascript或JQuery通过Element Value检索XML节点
