I know the error is occurring because of this line: System.out.println("caffeineIntake");
I want to access this input variable i.e. caffeineIntake to perform some operation on it.

The error is not occurring because of this line: System.out.println("caffeineIntake");
It is occurring because of the Dialect option selection:
Using this option as mvel rather than java resolved the issue.

Well,
from my point of view
String noOfCups = 1;
is the problem.
perhaps change it to
String noOfCups = "1";

Is there a way of doing this in JAXB & xsd??

Should be no problem, neither with DOM nor with JAXB. In JAXB you should simply be able to create a new SimilarModel object which you then can add in the SimilarModels object's list.

How to get the annotated text for a DictionaryAnnotator

I have a dictionary created from the DictionaryCreator from UIMA, I would like to annotate a piece of text using the DictionaryAnnotator and the aforementioned dictionary, I could not figure out how to get the annotated text. Please let me know if you do. Any help is appreciated. The code, the dictionary-file and the descriptor is mentioned below,
P.S. I'm new to Apache UIMA.
XMLInputSource xml_in = new XMLInputSource("DictionaryAnnotatorDescriptor.xml");
ResourceSpecifier specifier = UIMAFramework.getXMLParser().parseResourceSpecifier(xml_in);
AnalysisEngine ae = UIMAFramework.produceAnalysisEngine(specifier);
JCas jCas = ae.newJCas();
String inputText = "Mark and John went down the rabbit hole to meet a wise owl and have curry with the owl.";
jCas.setDocumentText(inputText);
printResults(jCas);
public static void printResults(JCas jcas) {
FSIndex<Annotation> index = jcas.getAnnotationIndex();
for (Iterator<Annotation> it = index.iterator(); it.hasNext(); ) {
Annotation annotation = it.next();
List<Feature> features;
features = annotation.getType().getFeatures();
List<String> fasl = new ArrayList<String>();
for (Feature feature : features) {
try {
String name = feature.getShortName();
System.out.println(feature.getName());
String value = annotation.getStringValue(feature);
fasl.add(name + "=\"" + value + "\"");
System.out.println(value);
}catch (Exception e){
continue;
}
}
}

Alternatively, you could also use Apache Ruta, either with the workbench (recommended to get started) or with java code.
For the latter, I created an example project at https://github.com/renaud/annotate_ruta_example. The main parts are:
a list of names in src/main/resources/ruta/resources/names.txt (a plain text file)
Mark
John
Rabbit
Owl
Curry
ATH-MX50
CC234
a Ruta script in src/main/resources/ruta/scripts/Example.ruta
PACKAGE example.annotate; // optional package def
WORDLIST MyNames = 'names.txt'; // declare dictionary location
DECLARE Name; // declare an annotation
Document{-> MARKFAST(Name, MyNames)}; // annotate document
and some java boilerplate code to launch the annotator:
JCas jCas = JCasFactory.createJCas();
// the sample text to annotate
jCas.setDocumentText("Mark wants to buy CC234.");
// configure the engine with scripts and resources
AnalysisEngine rutaEngine = AnalysisEngineFactory.createEngine(
RutaEngine.class, //
RutaEngine.PARAM_RESOURCE_PATHS,
"src/main/resources/ruta/resources",//
RutaEngine.PARAM_SCRIPT_PATHS,
"src/main/resources/ruta/scripts",
RutaEngine.PARAM_MAIN_SCRIPT, "Example");
// run the script. instead of a jCas, you could also provide a UIMA collection reader to process many documents
SimplePipeline.runPipeline(jCas, rutaEngine);
// a simple select to print the matched Names
for (Name name : JCasUtil.select(jCas, Name.class)) {
System.out.println(name.getCoveredText());
}
there is also some UIMA type (annotation) definitions, check src/main/resources/desc/type/ExampleTypes.xml, src/main/resources/META-INF/org.apache.uima.fit/types.txt and src/main/java/example/annotate.
how to test it
git clone https://github.com/renaud/annotate_ruta_example.git
cd annotate_ruta_example
mvn clean install
mvn exec:java -Dexec.mainClass="example.Annotate"

I want to delete all <resver> elements except for the one with highest "major" attribute value.
For example above major="71" is highest in the first resver group and major="87" is the highest in second resver group.

I thought of using JAXB to do the work. Is there a better way to solve this?
Can this be done with Simple Java File api?
Answer
I have written this thing using JAXB to acheive this.
Here is the code
try {
File file = new File(FILE);
JAXBContext jaxbContext = JAXBContext.newInstance(Package.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
Package pack = (Package) jaxbUnmarshaller.unmarshal(file);
if (pack.getRes() == null || pack.getRes().size() == 0) {
System.out.println("Size zero - exit");
return;
}
for (Package.Res res : pack.getRes()) {
if (! (res.getResver().size() == 1)) {
Short max = getMaxMajorVersion(res);
List<Package.Res.Resver> resverList = removeNonMaxResver(res, max);
for (Package.Res.Resver resver : resverList)
res.getResver().remove(resver);
}
}
finalPack = pack;
} catch (JAXBException e) {
e.printStackTrace();
}
marshal();
Method: extractNonMaxResver
private static List<Package.Res.Resver> removeNonMaxResver(
Package.Res res, Short max) {
List<Package.Res.Resver> resverList = new ArrayList<Package.Res.Resver>();
for (Package.Res.Resver resver : res.getResver()) {
if (resver.getMajor() != max)
resverList.add(resver);
}
return resverList;
}
Method: getMaxMajorVersion
private static Short getMaxMajorVersion(Package.Res res) {
List<Short> list = new ArrayList<Short>();
for (Package.Res.Resver resver : res.getResver()) {
list.add(resver.getMajor());
}
Short max = Collections.max(list);
System.out.println("Max: " + max);
return max;
}
Method: marshal
public static void marshal() {
try {
File file = new File(FILE_OUT);
JAXBContext jaxbContext = JAXBContext.newInstance(Package.class);
Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
// output pretty printed
jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,
Boolean.TRUE);
jaxbMarshaller.marshal(finalPack, file);
jaxbMarshaller.marshal(finalPack, System.out);
} catch (JAXBException e) {
e.printStackTrace();
}
}

You need to load the XML into either XMLElement or a Java object(using JAXB or other lib). If using XMLEement then you will be iterating through nodes and deleting as per your condition. and in case of Java Model object, just iterate through the list delete them and then persist the same Model as XML file.
Go through the Java Docs :https://docs.oracle.com/javase/7/docs/api/org/w3c/dom/Element.html
It has all API which you can use to manipulate XML.

XML is not a programming language.
you cant add conditions on it, but the same is possible with processing languages such as XSLT.
<xsl:if test="#foo='bar'">
<xsl:text>Hello, world!</xsl:text>
</xsl:if>
I suggest that as the best way to do this kind of operations.
Other possible operations are by parsing the XML String using basic String operations. Its complex and confusing and more error prone.
