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。特别是我想要解析lineItems
的值及其属性coaCode
的值,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,它会在
行崩溃 var values = elements[i].getChildren('Statement').getChildren('lineItem');
错误消息:
TypeError: Cannot find function getChildren in object [Element: <Statement/>],
[Element: <Statement/>],[Element: <Statement/>].
我试图找到错误几个小时,但没有成功(我尝试了.getChildren
组合的不同变体)。
您对我的代码可能出现的问题有什么想法吗?
答案 0 :(得分:2)
对于这样的XML:
<ReportFinancialStatements Major="1" Minor="0" Revision="1">
<FinancialStatements>
<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>
</AnnualPeriods>
</FinancialStatements>
</ReportFinancialStatements>
变化:
...
//var values = elements[i].getChildren('Statement').getChildren('lineItem');
var values = elements[i].getChildren('Statement')[0].getChildren('lineItem');
...
答案 1 :(得分:0)
或者,您可以进行以下更改:
//var values = elements[i].getChildren('Statement').getChildren('lineItem');
var values = elements[i].getChild('Statement').getChild('lineItem');
这个以及@wchiquito提到的代码更改将在数据存在于第一个&#34; Statement&#34;节点
