从模板生成 XML 并用新数据填充它答案

【问题标题】：Generate XML from template and fill it with new data从模板生成 XML 并用新数据填充它
【发布时间】：2011-07-01 14:20:27
【问题描述】：

我有一些 XML（超过 150 个标签）。
我需要基于该模板创建另外 50 个 xml 文件，但使用另一个标记值。
所以我生成了随机数据（以 xls、csv、sql 格式保存），我需要在模板中填写这些值并用新名称保存。我怎么能做到这一点？（unix shell 脚本、java、软件等）

谢谢

【解决方案1】：

假设您能够使用 SQL Server - 查看 FOR XML

我觉得会很复杂，但我会试试
只根据您的要求复杂 - 首先尝试一些简单的方法，例如 SELECT * FROM Customers FOR XML AUTO、返回 XML 数据类型的 TYPE 或 SELECT * FROM Customers FOR XML AUTO 将 XML 内容作为varchar
看来我的问题类似于stackoverflow.com/questions/4267427/…

【解决方案2】：

@BonyT，谢谢，你告诉我正确的方向，我正在使用 db2，所以对我来说答案是：

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（所有生成的 XML 保存在一个文件中c:\temp\xml\tmp_xml2.001.xml - 我没有找到单独保存 XML 的方法）

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' />"
