我正在尝试使用 Google 电子表格中的 Google Apps 脚本解析以下 XML 文档。特别是我想解析lineItems
其属性的值和值coaCode
,例如 RTLR = 50211.000000:
<ReportFinancialStatements Major="1" Minor="0" Revision="1">
<FinancialStatements>
<COAMap></COAMap>
<AnnualPeriods>
<FiscalPeriod Type="Annual" EndDate="2009-06-30" FiscalYear="2009">
<Statement Type="INC">
<FPHeader>
<PeriodLength>12</PeriodLength>
<Source Date="2009-09-23">ARS</Source>
</FPHeader>
<lineItem coaCode="SREV">50211.000000</lineItem>
<lineItem coaCode="RTLR">50211.000000</lineItem>
<lineItem coaCode="SCOR">12001.000000</lineItem>
</Statement>
</FiscalPeriod>
这是我的代码片段:
function parse(txt) {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];
var document = XmlService.parse(txt);
var root = document.getRootElement();
var elements = root.getChild('FinancialStatements').
getChild('AnnualPeriods').getChildren('FiscalPeriod');
var columnOffset = 2;
var rowOffset = 5;
for (var i = 0; i < elements.length; i++) {
var column = elements.length - i + columnOffset;
var endDate = elements[i].getAttribute('EndDate').getValue();
var fiscalYear = elements[i].getAttribute('FiscalYear').getValue();
var fiscalPeriodType = elements[i].getAttribute('Type').getValue();
// ***** SCRIPT CRASHES HERE: *****
var values = elements[i].getChildren('Statement').getChildren('lineItem');
for (var j = 0; j < values.length; j++) {
var row = j + rowOffset;
var value = values[j].getValue();
sheet.getRange(row,column).setValue(value);
}
}
}
当我运行代码时,它在该行崩溃
var values = elements[i].getChildren('Statement').getChildren('lineItem');
带有错误消息:
TypeError: Cannot find function getChildren in object [Element: <Statement/>],
[Element: <Statement/>],[Element: <Statement/>].
我试图找出错误几个小时,但没有成功(我尝试了不同的.getChildren
组合变体)。
您对我的代码可能有什么问题有任何想法吗?
