populate XML with value from another XML

[Andrew Cane]

I have a config file (lets call this file main-config.xml) with a list of environments of databases for my app.
The question now, I have several frameworks that requires the information from inside main-config.xml, but different format (hibernate wants its own config format and mybatis wants its own format). so how can I populate the hibernate's and mybatis' config file based on the value in main-config.xml. thanks

I suggest you start by working with simpler XML exercises until you get comfortable with the Java standard library for XML.

This free online book by Harold is loaded with good examples.

umm, I've been working with XML for quite a while along with XSLT. I don't understand how the article can help me with thisissue, am I missing something? thanks

I can think of two ways to address this.

1) Keep all those properties in some file format of your own choosing, and create all the config files for the various subsystems as part of the build process from that.

2) Write code that reads the properties at startup time, and then initialize the other libraries programmatically.

so, there's no way to do something like

general.properties

jdbc.url=abc://def.ghi.jkl
.......

mybatis-cfg-xml

<dataSource type="POOLED" ref="../../properties/general.properties">
  ......
  <property name="url" value="${jdbc.url}"/>
</dataSource>

so, it won't involve any kind of code involvement, just pure XML reading another XML / properties file
thanks

A google search for XML include found this article.

Why not just use a properties file with unique keys of course for different DB storing such info rather than creating another XML?

@william brogden:
yep, this is what I've been looking for.

K. Tsang:
yes, properties file would also work, its just my team prefer XML because utility class that processes XML already exist. its just a matter of habit I guess. can you give me an example of how this works?

is xi:include the common way in reusing information stored in one main configuration file by different frameworks config file?
