我想使用xmlbuilderin制作一个 XML 文件node.js。但它的结束标签在一种情况下丢失

var root = builder.create('ENVELOPE');

root.ele('HEADER')
    .ele('TALLYREQUEST').txt('Import Data').up().up()
    .ele('BODY')
    .ele('IMPORTDATA')
    .ele('REQUESTDESC')
    .ele('REPORTNAME').txt('All Masters').up()
    .ele('STATICVARIABLES')
    .ele('SVCURRENTCOMPANY').txt('Private Limited').up().up().up()
    .ele('REQUESTDATA')
    .ele('TALLYMESSAGE').att('xmlns:UDF', 'TallyUDF')
    .ele('VOUCHER').att('REMOTEID', '00002285').att('VCHKEY', '0000038')
    .att('VCHTYPE', 'MTC').att('ACTION', 'Create').att('OBJVIEW', 'Accounting Voucher View')
    .ele('OLDAUDITENTRYIDS.LIST').att('TYPE', "NUMBER")
    .ele('OLDAUDITENTRYIDS').txt('-1').up().up()
    .ele('DATE').txt('20210920').up()

var xml = root.end({ pretty: true });
console.log(xml);

上面的代码将给出如下输出，这就是我想要的

<?xml version="1.0" encoding="UTF-8"?><ENVELOPE><HEADER>
<TALLYREQUEST>Import Data</TALLYREQUEST></HEADER><BODY>
<IMPORTDATA>
    <REQUESTDESC>
        <REPORTNAME>All Masters</REPORTNAME>
        <STATICVARIABLES>
            <SVCURRENTCOMPANY>Private Limited</SVCURRENTCOMPANY>
        </STATICVARIABLES>
    </REQUESTDESC>
    <REQUESTDATA>
        <TALLYMESSAGE xmlns:UDF="TallyUDF">
            <VOUCHER REMOTEID="00002285" VCHKEY="0000038" VCHTYPE="MTC" ACTION="Create" OBJVIEW="Accounting Voucher View">
            <OLDAUDITENTRYIDS.LIST TYPE="NUMBER">
                <OLDAUDITENTRYIDS>-1</OLDAUDITENTRYIDS>
            </OLDAUDITENTRYIDS.LIST>
            <DATE>20210920</DATE>
            </VOUCHER>
        </TALLYMESSAGE>
    </REQUESTDATA>
</IMPORTDATA></BODY></ENVELOPE>

但是如果我为重复的代码设置一个循环，那么它会产生一个问题

var root = builder.create('ENVELOPE');
root.ele('HEADER')
    .ele('TALLYREQUEST').txt('Import Data').up().up()
    .ele('BODY')
    .ele('IMPORTDATA')
    .ele('REQUESTDESC')
    .ele('REPORTNAME').txt('All Masters').up()
    .ele('STATICVARIABLES')
    .ele('SVCURRENTCOMPANY').txt('Private Limited').up().up().up()
    .ele('REQUESTDATA');
    
for (let i = 0; i < 2; i++) {
    root.ele('TALLYMESSAGE').att('xmlns:UDF', 'TallyUDF')
        .ele('VOUCHER').att('REMOTEID', '00002285').att('VCHKEY', '0000038')
        .att('VCHTYPE', 'MTC').att('ACTION', 'Create').att('OBJVIEW', 'Accounting Voucher View')
        .ele('OLDAUDITENTRYIDS.LIST').att('TYPE', "NUMBER")
        .ele('OLDAUDITENTRYIDS').txt('-1').up().up()
        .ele('DATE').txt('20210920').up()
}

var xml = root.end({ pretty: true });
console.log(xml);

上述代码的输出如下。最后要关闭的标签将首先关闭

<?xml version="1.0" encoding="UTF-8"?><ENVELOPE><HEADER>
<TALLYREQUEST>Import Data</TALLYREQUEST></HEADER><BODY>
<IMPORTDATA>
    <REQUESTDESC>
        <REPORTNAME>All Masters</REPORTNAME>
        <STATICVARIABLES>
            <SVCURRENTCOMPANY>Private Limited</SVCURRENTCOMPANY>
        </STATICVARIABLES>
    </REQUESTDESC>
    <REQUESTDATA />
</IMPORTDATA></BODY><TALLYMESSAGE xmlns:UDF="TallyUDF">
<VOUCHER REMOTEID="00002285" VCHKEY="0000038" VCHTYPE="MTC" ACTION="Create" OBJVIEW="Accounting Voucher View">
    <OLDAUDITENTRYIDS.LIST TYPE="NUMBER">
        <OLDAUDITENTRYIDS>-1</OLDAUDITENTRYIDS>
    </OLDAUDITENTRYIDS.LIST>
    <DATE>20210920</DATE>
</VOUCHER></TALLYMESSAGE></ENVELOPE>

请帮我解决这个问题，这将是一个很大的帮助
