javascript - 解析 Jquery Ajax 中的嵌套 XML 响应

Question

我正在编写一个 asp.net web api web 服务。除了服务之外，我还编写了一个测试程序，以便可以测试 Web 服务。

测试器允许您发布和接收 JSON 或 XML。我正在使用 jquery ajax 处理响应。我可以很好地使用 JSON，下面的代码也可以正常工作。

JSON 响应

{"ItemLabel":
    {"Requisition":"W44DQ18255TS42 ",
    "Nsn":"5999-01-100-5901",
    "FscNiin":"5999011005901 ",
    "Cage":"1CAY9",
    "PartNumber":"",
    "Nomen":"CONTACT,ELECTRICAL ",
    "Quantity":"1",
    "Ui":"EA",
    "UiDesc":"",
    "PurchOrderNbr":"SPM907-85-5-4444",
    "RlseNbr":"TS0042",
    "Clin":"0042 ",
    "Lot":"",
    "Preservation":"",
    "DatePreserved":"",
    "ShelfType":"",
    "Shelf1":"",
    "Exp1":"",
    "CureDt1":"",
    "CureInsp1":"",
    "Shelf2":"",
    "Exp2":"",
    "CureDt2":"",
    "CureInsp2":"",
    "Serials":"",
    "Serial":null,
    "SerialInters":null,
    "UnitPerInt":"1",
    "TypeLbl":"ITEMx1"
    },
"filePaths":["https://xxxxxxxxxxx.dir.ad.dla.mil/pdf/email_ITEMLBL__W44DQ18255TS42 _682895.pdf"]
}

我可以使用 jquery ajax 处理结果，如下所示。

 success: function (result) {
                            $('#Spinner129').hide();
                            self.jsonResponse129(JSON.stringify(result));
                            self.hasSuccess129(true);
                            self.successMessage129("Success! Please view the response in the JSON Response tab below.");
                            $.each(result.filePaths, function (i, path) {
                                window.open(path, '_blank');                               
                            });
                        },

虽然我在使用 xml 响应做同样的事情时遇到了一些困难，但如何获取文件路径中的值？

这是 xml 响应

不确定如何在 jquery ajax 成功部分处理它，这是我的尝试。

 success: function (result) {
                            $('#Spinner129').hide();
                            self.hasSuccess129(true);                          
                            self.successMessage129("Success! Please view the response in the XML Response tab below.");
                            self.xmlResponse129(JSON.stringify(result));
                           // xmlDoc = $.parseXML(result),
                         //  $xml = $(xmlDoc),
                          // $filePath = $xml.find("filePaths");
                          //  now what?
                        },

文件路径嵌套在 filePaths 节点的子节点内。

<filePaths xmlns:d2p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
   <d2p1:string>https://xxxxxxxxxxx.dir.ad.dla.mil/pdf/email_ITEMLBL__W44DQ18255TS42 _405955.pdf</d2p1:string>
</filePaths>

一旦您拥有如下所示的 $filePaths:

$filePaths = $xml.find("filePaths");

您可以访问其子项，然后获取其文本:

$filePaths.children().each(function () { 
    //console.log($(this).text()); // print to test
    // https://xxxxxxxxxxx.dir.ad.dla.mil/pdf/email_ITEMLBL__W44DQ18255TS42 _405955.pdf

    // open in new window
    window.open($(this).text(), '_blank');         
});
