如何在awk循环后打印一行?

我有一个打印标题信息的awk脚本,然后遍历csv文件以创建xml输出。我希望在循环完成后打印一行,但是以下脚本将标记放在每行之后而不是仅放在文件末尾。我有什么不对?

BEGIN { FS="," }
NR==1 {
{print "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" > "output.xml" }
{print "<Batch>" > "output.xml" }
{print "  <ASWFileVersion>" > "output.xml" }
{print "    <Application>Batch Maintenance</Application>" > "output.xml" }
{print "    <FileFormat>BATCH_XML_01</FileFormat>" > "output.xml" }
{print "    <Release> </Release>" > "output.xml" }
{print "  </ASWFileVersion>" > "output.xml" }
{print "  <BatchHeader>" > "output.xml" }
{print "    <BatchId>965</BatchId>" > "output.xml" }
{print "    <UserBatchId>965</UserBatchId>" > "output.xml" }
{print "    <BatchType>O</BatchType>" > "output.xml" }
{print "    <Description>Brdata Customer Import</Description>" > "output.xml" }
{print "    <CreatedOn>2014-12-05T12:35:30.3930000-05:00</CreatedOn>" > "output.xml" }
{print "    <TargetData>BatchCustomer</TargetData>" > "output.xml" }
{print "    <SaleLevel>0</SaleLevel>" > "output.xml" }
{print "    <Status> </Status>" > "output.xml" }
{print "    <ErrorMessage> </ErrorMessage>" > "output.xml" }
{print "  </BatchHeader>" > "output.xml" }
for (i=1; i<=NF; i++) {
        tags[i] = $i
    }
    next
}
{
    print "<BatchCustomer>" > "output.xml"
    for (i=1; i<=NF; i++) {
        printf "    <%s>%s</%s>\n", tags[i], $i, tags[i] > "output.xml"
    }
    print "</BatchCustomer>" > "output.xml"
}
{print "</Batch>" > "output.xml" }

我使用以下命令:

sudo gawk -f tst.awk customers.csv 

运行该文件。输入文件是customers.csv,文件包含成为标记的标题。该脚本生成一个名为output.csv的文件。我需要标记仅位于文件的底部,而不是在从行生成的每个段的末尾。我做错了什么想法?

你可能意味着

END {print "</Batch>" > "output.xml" }

其余的代码也非常糟糕,为什么要重定向每次写入而不是简单地重定向整个输出?
