如何将表单数据调用为xml表单

Question

您好我正在处理一些Web应用程序，并且在我可以保存到数据库之前，首先将输入表单值传递给xml表单。但是，当我传递以下数据时，它无法正常工作。这是正确的做法。

<?xml version="1.0" encoding="utf-8"?>
    <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
      <soap:Body>
        <PostTransaction xmlns="http://PegPayTelecomsApi/">
          <trans>
            <DigitalSignature>de96d901b3bad1db2aab76b7b0b202f2</DigitalSignature>
            <FromTelecom>#{params[:pay_type]}</FromTelecom>
            <ToTelecom>#{params[:pay_type]}</ToTelecom>
            <PaymentCode>1</PaymentCode>
            <VendorCode>TEST</VendorCode>
            <Password>61T05DB750</Password>
            <PaymentDate>01/01/2014</PaymentDate>
            <Telecom></Telecom>
            <CustomerRef>#{params[:phone_no]}</CustomerRef>
            <CustomerName>#{params[:name]}</CustomerName>
            <TranAmount>10000</TranAmount>
            <TranCharge>0</TranCharge>
            <VendorTranId>1</VendorTranId>
            <ToAccount></ToAccount>
            <FromAccount>#{params[:phone_no]}</FromAccount>
            <TranType>PULL</TranType>
          </trans>
        </PostTransaction>
      </soap:Body>
    </soap:Envelope>
