xml - 如何访问 XML 响应的子级 - Google Apps 脚本

问题描述

我正在构建一个函数，它应该获取 XML 响应的元素并将元素的每次迭代存储在电子表格中它自己的行中，直到所有元素都被考虑在内。请参阅下面的代码，我可以将元素标题和值打印到记录器，但不能访问每个值以传输到工作表。请指教。

function testPOST(e) {

var url = "API_URL";

var payload = e;

var options =
    {
      "method"  : "POST",
      "payload" : payload,   
      "followRedirects" : true,
      "muteHttpExceptions": true
    };

var result = UrlFetchApp.fetch(url, options);

if (result.getResponseCode() == 200) {
  //    Logger.log(result);
  Logger.log(result.getResponseCode() + "\n\n");
}

/*TESTING*/
var od = XmlService.parse(result);
pm = XmlService.getPrettyFormat().format(od);
Logger.log(pm);

/* Preferred Approach */  
var ss = SpreadsheetApp.openById("SPREADSHEET_ID").getSheetByName("Output"),
    temps = [],
    root = XmlService.parse(result).getRootElement().getDescendants(),
    temps = root;
for (var [key,val] in temps)
{
  if(val == "")
  {
    continue;
  }
  else{
    //      Logger.log("Index Value:"+e.values[key]+"\n");
    Logger.log(key+" Value:"+val+ "\n");  
  }
}
}

这是记录器输出的示例。

解决方案

  • 您希望通过解析 XML 数据将值放入电子表格。
  • 在您的示例 XML 数据中，用于放入电子表格的标题和值如下所示。
    • 标题：userID webExId firstName lastName email userRoleType registrationDate active timeZoneID lastLoginTime
    • 价值观：
      • UID ID NAME NAME EMAIL HOST DATE ACTIVATED 11 DATE
      • UID ID NAME NAME EMAIL SITEADMIN DATE ACTIVATED 7 DATE

我可以像上面那样理解。如果我的理解是正确的，那么这个示例脚本怎么样？请认为这只是几个答案之一。

示例脚本：

在运行脚本之前，请设置电子表格 ID。

function myFunction() {
  var id = "###"; // <--- Please set the Spreadsheet ID here.

  // This is the sample XML data from your updated question.
  var result = '<?xml version="1.0" encoding="UTF-8"?><serv:message xmlns:serv="http://www.webex.com/schemas/2002/06/service" xmlns:com="http://www.webex.com/schemas/2002/06/common" xmlns:use="http://www.webex.com/schemas/2002/06/service/user"><serv:header><serv:response><serv:result>SUCCESS</serv:result><serv:gsbStatus>PRIMARY</serv:gsbStatus></serv:response></serv:header><serv:body><serv:bodyContent xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="use:lstsummaryUserResponse"><use:user><use:userID>UID</use:userID><use:webExId>ID</use:webExId><use:firstName>NAME</use:firstName><use:lastName>NAME</use:lastName><use:email>EMAIL</use:email><use:userRoleType>HOST</use:userRoleType><use:registrationDate>DATE</use:registrationDate><use:active>ACTIVATED</use:active><use:timeZoneID>11</use:timeZoneID><use:lastLoginTime>DATE</use:lastLoginTime></use:user><use:user><use:userID>UID</use:userID><use:webExId>ID</use:webExId><use:firstName>NAME</use:firstName><use:lastName>NAME</use:lastName><use:email>EMAIL</use:email><use:userRoleType>SITEADMIN</use:userRoleType><use:registrationDate>DATE</use:registrationDate><use:active>ACTIVATED</use:active><use:timeZoneID>7</use:timeZoneID><use:lastLoginTime>DATE</use:lastLoginTime></use:user><use:matchingRecords><serv:total>2</serv:total><serv:returned>2</serv:returned><serv:startFrom>1</serv:startFrom></use:matchingRecords></serv:bodyContent></serv:body></serv:message>';

  var header = [];
  var values = [];
  var root = XmlService.parse(result).getRootElement();
  var c1 = root.getChildren();
  for (var i = 0; i < c1.length; i++) {
    if (c1[i].getName() == "body") {
      var c2 = c1[i].getChildren()[0].getChildren();
      for (var j = 0; j < c2.length; j++) {
        if (c2[j].getName() == "user") {
          var c3 = c2[j].getChildren();
          var temp = [];
          for (var k = 0; k < c3.length; k++) {
            if (j == 0) header.push(c3[k].getName());
            temp.push(c3[k].getValue());
          }
          values.push(temp);
        }
      }
    }
  }
  values.unshift(header);

  var sheet = SpreadsheetApp.openById(id).getSheetByName("Output");
  sheet.getRange(1, 1, values.length, values[0].length).setValues(values);
}

笔记：

  • 在您的示例 XML 数据中，每个元素的顺序是相同的。这个脚本使用这个。如果顺序是随机的，首先需要声明头部。
