Include tag in jaxb

I have an xml file of following structure:
<root>
<paramsToInclude>
<params id="id1">
<param11>val1</param11>
<param12>val2</param12>
<param13>val3</param13>
<param14>val4</param14>
</params>
<params id="id3">
<param31>val1</param31>
<param32>val2</param32>
</params>
</paramsToInclude>
<process>
<subprocess1>
<include params="id1"/>
<query>
SELECT *
FROM
table;
</query>
</subprocess2>
<subprocess1>
<rule>rule1</rule>
<rule>rule2</rule>
</subprocess2>
<subprocess3>
<processParam>val1</processParam>
<include params="id2"/>
<include params="id3"/>
</subprocess3>
</process>
I'm using jaxb to parse this xml into the java classes. Is there a way to substitute includes in the process by it's values from the begin of file? I mean, I wan't file to be parsed as if it look's like
<root>
<paramsToInclude>
<params id="id1">
<param11>val1</param11>
<param12>val2</param12>
<param13>val3</param13>
<param14>val4</param14>
</params>
<params id="id3">
<param31>val1</param31>
<param32>val2</param32>
</params>
</paramsToInclude>
<process>
<subprocess1>
<param11>val1</param11>
<param12>val2</param12>
<param13>val3</param13>
<param14>val4</param14>
<query>
SELECT *
FROM
table;
</query>
</subprocess2>
<subprocess1>
<rule>rule1</rule>
<rule>rule2</rule>
</subprocess2>
<subprocess3>
<processParam>val1</processParam>
<param11>val1</param11>
<param12>val2</param12>
<param13>val3</param13>
<param14>val4</param14>
<param31>val1</param31>
<param32>val2</param32>
</subprocess3>
</process>
is it possible t do this? I've found link http://thetechietutorials.blogspot.com/2011/08/jaxb-tutorial-part-2-jaxb-with-xinclude.html how to this include from another file, but comment says that it's impossible to do this for the same file (I understand that I can put this includes in another xml, but I don't think it's a best way). Also I don't want to use hashMap because in this way included params will be stored in hashMap and processParam (from subprocess3) will be class variable.
Is there a way to do this somehow?

Tool or schema that describes Adobe Premiere Pro

I have some data outside that i would like to use to create certain edit effects in Adobe Premiere Pro. Rather than editing by hand adding keyframes over time with my data i would like to automate this and write or use a tool to create an XML fragment and update the project file.
I have looked at the XML and some properties are evident. However most data is hidden away as comma separated values, which of course means theres no self documenting tag name. I am therefore after a schema or documentation that describes the format of some or all effects.

<DiscontinuousInterpolate>false</DiscontinuousInterpolate>
<IsLocked>false</IsLocked>
<IsTimeVarying>true</IsTimeVarying>
<Name>Rotation</Name>
</VideoComponentParam>
The interesting tag is of course the Keyframes, which appears to include the keyframe, rotation degrees and some other numbers. I havent yet decyphered the first value which is obviously the timestamp.
Any help in undetrstnding the XML is appreciated.

FINAL CUT PRO XML
I have exported a simple project to Final Cut Pro XML and it appears to be functional but in the above case about rotation over several keyframes, the FCP file has far fewer values.
<parameter authoringApp="PremierePro">
<parameterid>rotation</parameterid>
<name>Rotation</name>
<valuemin>-8640</valuemin>
<valuemax>8640</valuemax>
<value>0</value>
<keyframe>
<when>107634</when>
<value>123</value>
</keyframe>
<keyframe>
<when>107784</when>
<value>124</value>
</keyframe>
<keyframe>
<when>107934</when>
<value>126</value>
</keyframe>
</parameter>

Here is full description of Final Cut XML format. it is same as Premiere XML.
Go to developer.apple.com and find the document that describes FinalCutPro XML format, it's exact the same as Premiere pro XML. The structure is simple, for example this is sequence block format:
<?xml version="1.0" encoding="UTF-8"?>
<xmeml version="3">
<sequence>
<name>Sequence 1</name>
<duration></duration>
<rate>. . .</rate>
<timecode>. . .</timecode>
<media>
<video>
<format></format>
<track></track>
</video>
<audio>
<format></format>
<outputs></outputs>
<track></track>
<track></track>
</audio>
</media>
</sequence>
</xmeml>

THe best solution is to make changes and study the file differences with your favourite diff'ing tool. Its not terribly difficult to understand small fragments and hand edit the XML. Naturally its a pain to make a change and reload the project file and observe the changes, buts its doable.

How to split xml to header and items using smooks?

I have a xml file roughly like this:
<batch>
<header>
<headerStuff />
</header>
<contents>
<timestamp />
<invoices>
<invoice>
<invoiceStuff />
</invoice>
<!-- Insert 1000 invoice elements here -->
</invoices>
</contents>
</batch>
I would like to split that file to 1000 files with the same headerStuff and only one invoice. Smooks documentation is very proud of the possibilities of transformations, but unfortunately I don't want to do those.
The only way I've figured how to do this is to repeat the whole structure in freemarker. But that feels like repeating the structure unnecessarily. The header has like 30 different tags so there would be lots of work involved also.
What I currently have is this:
<?xml version="1.0" encoding="UTF-8"?>
<smooks-resource-list xmlns="http://www.milyn.org/xsd/smooks-1.1.xsd"
xmlns:calc="http://www.milyn.org/xsd/smooks/calc-1.1.xsd"
xmlns:frag="http://www.milyn.org/xsd/smooks/fragment-routing-1.2.xsd"
xmlns:file="http://www.milyn.org/xsd/smooks/file-routing-1.1.xsd">
<params>
<param name="stream.filter.type">SAX</param>
</params>
<frag:serialize fragment="INVOICE" bindTo="invoiceBean" />
<calc:counter countOnElement="INVOICE" beanId="split_calc" start="1" />
<file:outputStream openOnElement="INVOICE" resourceName="invoiceSplitStream">
<file:fileNamePattern>invoice-${split_calc}.xml</file:fileNamePattern>
<file:destinationDirectoryPattern>target/invoices</file:destinationDirectoryPattern>
<file:highWaterMark mark="10"/>
</file:outputStream>
<resource-config selector="INVOICE">
<resource>org.milyn.routing.io.OutputStreamRouter</resource>
<param name="beanId">invoiceBean</param>
<param name="resourceName">invoiceSplitStream</param>
<param name="visitAfter">true</param>
</resource-config>
</smooks-resource-list>
That creates files for each invoice tag, but I don't know how to continue from there to get the header also in the file.
EDIT:
The solution has to use Smooks. We use it in an application as a generic splitter and just create different smooks configuration files for different types of input files.

I just started with Smooks myself. However... your problem sounds identical to this: http://www.smooks.org/mediawiki/index.php?title=V1.5:Smooks_v1.5_User_Guide#Routing_to_File
You will have to provide the output FTL format in whole, that's the downside of using a general purpose tool I guess. Data mapping often includes a lot of what feels like redundancy, one way around this is to leverage convention but that has to be built into the framework.

I don't know smooks, but the simplest solution (with poor performance) would be (to create the Nth file):
copy the whole xml structure
delete all the invoice tags but the Nth one
I don't know how to do that in smooks, that only an idea. In this case you don't need to duplicate the structure of the xml in a freemarker template.

Ant and XML configuration file parsing

I have an XML file of the following form -
<map MAP_XML_VERSION="1.0">
<entry key="database.user" value="user1"/>
...
</map>
Does ant have a native ability to read this and let me perform an xquery to pull back values for keys? Going through the API I did not see such capabilities.

The optional Ant task XMLTask is designed to do this. Give it an XPath expression and you can select the above into (say) a property. Here's an article on how to use it, with examples. It'll do tons of other XML-related manipulations/querying/creation as well.
e.g.
<xmltask source="map.xml">
<!-- copies to a property 'user' -->
<copy path="/map/entry[#key='database.user']/#value" attrValue="true" property="user"/>
</xmltask>
Disclaimer: I'm the author.

You can use the scriptdef tag to create a JavaScript wrapper for your class. Inside JS, you pretty much have the full power of Java and can do any kind of complicated XML parsing you want.
For example:
<project default="build">
<target name="build">
<xpath-query query="//entry[#key='database.user']/#value"
xmlFile="test.xml" addproperty="value"/>
<echo message="Value is ${value}"/>
</target>
<scriptdef name="xpath-query" language="javascript">
<attribute name="query"/>
<attribute name="xmlfile"/>
<attribute name="addproperty"/>
<![CDATA[
importClass(java.io.FileInputStream);
importClass(javax.xml.xpath.XPath);
importClass(javax.xml.xpath.XPathConstants);
importClass(javax.xml.xpath.XPathFactory);
importClass(org.xml.sax.InputSource);
var exp = attributes.get("query");
var filename = attributes.get("xmlfile");
var input = new InputSource(new FileInputStream(filename));
var xpath = XPathFactory.newInstance().newXPath();
var value = xpath.evaluate(exp, input, XPathConstants.STRING);
self.project.setProperty( attributes.get("addproperty"), value );
]]>
</scriptdef>
</project>

Sounds like you want something like ant-xpath-task. I'm not aware of a built-in way to do this with Ant.

How to use size of file inside Ant target

I'm currently in the process of replacing my homebrewn build script by an Ant build script.
Now I need to replace various tokens by the size of a specific file. I know how to get the size in bytes via the <length> task and store in in a property, but I need the size in kilobytes and megabytes too.
How can I access the file size in other representations (KB, MB) or compute these values from within the Ant target and store them in a property?
Edit: After I discovered the <script> task, it was fairly easy to calculate the other values using some JavaScript and add a new property to the project using project.setNewProperty("foo", "bar");.

I found a solution that does not require any third-party library or custom tasks using the <script> task that allows for using JavaScript (or any other Apache BSF or JSR 223 supported language) from within an Ant target.
<target name="insert-filesize">
<length file="${afile}" property="fs.length.bytes" />
<script language="javascript">
<![CDATA[
var length_bytes = project.getProperty("fs.length.bytes");
var length_kbytes = Math.round((length_bytes / 1024) * Math.pow(10,2))
/ Math.pow(10,2);
var length_mbytes = Math.round((length_kbytes / 1024) * Math.pow(10,2))
/ Math.pow(10,2);
project.setNewProperty("fs.length.kb", length_kbytes);
project.setNewProperty("fs.length.mb", length_mbytes);
]]>
</script>
<copy todir="${target.dir}">
<fileset dir="${source.dir}">
<include name="**/*" />
<exclude name="**/*.zip" />
</fileset>
<filterset begintoken="$$$$" endtoken="$$$$">
<filter token="SIZEBYTES" value="${fs.length.bytes}"/>
<filter token="SIZEKILOBYTES" value="${fs.length.kb}"/>
<filter token="SIZEMEGABYTES" value="${fs.length.mb}"/>
</filterset>
</copy>
</target>

There is a math task at http://ant-contrib.sourceforge.net/ that may be useful
