我有一些XML（超過150個標籤）。
我需要基於該模板創建額外的50個xml文件，但需要使用另一個標記值。
所以我產生了隨機數據（保存爲xls，csv，sql格式），我需要在模板中填充該值並用新名稱保存。 我該怎麼做？ （UNIX shell腳本，JAVA，軟件等）
感謝從模板生成XML並填充新數據

假設你能夠使用SQL Server - 檢查出XML

@BonyT，謝謝，你告訴我正確的方向，我正在使用db2，所以對我來說，答案是：
db2 => EXPORT TO "c:\temp\xml.del" OF DEL XML TO "c:\temp\xml" XMLFILE "xml" MESSAGES "c:\temp\msg.txt" SELECT * FROM TMP.XML_TEMPLATE
其中xml.del（所有產生的個XML保存在一個文件c:\temp\xml\tmp_xml2.001.xml - 我沒有找到方法來單獨保存個XML）
6,"<XDS FIL='tmp_xml2.001.xml' OFF='0' LEN='34780' />"
5,"<XDS FIL='tmp_xml2.001.xml' OFF='34780' LEN='34780' />"
7,"<XDS FIL='tmp_xml2.001.xml' OFF='69560' LEN='34780' />"
