I'm working on a project that involves KML creation using Java. Currently, I'm fooling with the sample Java code from the KML example at Micromata Labs JAK Example. I tried to "extend" the code by adding multiple coordinates and getting two markers, but I could not get it to work. Can you please tell me how I can add multiple coordinates and put markers on them, and also, draw a line between the markers. Thank you for your help!
PS: I need to do this via the program. I saw sample code of them using DOM and XML, but not pure Java/JAK as such. Please guide me.
I got as far as this (updated):
kml.createAndSetDocument().withName("MyMarkers")
.createAndAddPlacemark().withName("London, UK").withOpen(Boolean.TRUE)
.createAndSetPoint().addToCoordinates(-0.126236, 51.500152);
kml.createAndSetDocument().withName("MyMarkers")
.createAndAddPlacemark().withName("Somewhere near London,UK").withOpen(Boolean.TRUE)
.createAndSetPoint().addToCoordinates(-0.129800,52.700152);
But I know I'm going wrong somewhere. Please point me in the right direction.
Here is the resulting KML output:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:xal="urn:oasis:names:tc:ciq:xsdschema:xAL:2.0">
<Document>
<name>MyMarkers</name>
<Placemark>
<name>Somewhere near London, UK</name>
<open>1</open>
<Point>
<coordinates>-0.1298,52.700152</coordinates>
</Point>
</Placemark>
</Document>
</kml>
I can't seem to access the Document again to add more placemarks. How do I do it?
Basically, you need to do:
Document document = kml.createAndSetDocument().withName("MyMarkers");
document.createAndAddPlacemark().withName("London, UK").withOpen(Boolean.TRUE)
.createAndSetPoint().addToCoordinates(-0.126236, 51.500152);
document.createAndAddPlacemark().withName("Somewhere near London,UK").withOpen(Boolean.TRUE)
.createAndSetPoint().addToCoordinates(-0.129800,52.700152);
Previously, you were creating a new document and setting it (as the only document!) in the kml object. Therefore, only the last entry was shown.
To put more than one Placemark in a KML file you need a Folder or a Document
A basic <kml> element contains 0 or 1 Feature
A Feature is an abstract element that can be a Placemark.
A Container extends Feature and
can be a Document or a Folder
To make a long story short, if you want multiple Placemarks, you need to include them in a Document or a Folder
<kml>
<Document>
<Placemark>
</Placemark>
...
<Placemark>
</Placemark>
</Document>
</kml>
The documentation is very bad.
final Kml kml = new Kml();
Document document = kml.createAndSetDocument();
listForms = formDAO.getAll();
for (Form list : listForms){
document.createAndAddPlacemark()
.withName(String.valueOf(list.getId()))
.withDescription(list.toStringKML())
.createAndSetPoint().addToCoordinates(-20.3978398, -43.5146653);
}
kml.setFeature(document);
kml.marshal(new File("test.kml"));

I need help in constructing XML dynamically. I have a XSD associated with the XML. Thing is my xml contains repititive elements/block. Sometimes it might contain 3 elements or sometime only one. Sample xml is below
<?xml version="1.0" encoding="utf-8"?>
<addml>
<objectStore>
<folder>
<folderProperties>
<documentId>str1234</documentId>
<documentTitle>str1234</documentTitle>
<dateCreated>str1234</dateCreated>
</folderProperties>
<documents>
<document>
<docProperties>
<documentId>str1234</documentId>
<documentTitle>str1234</documentTitle>
<dateCreated>str1234</dateCreated>
</docProperties>
</document>
<document>
<docProperties>
<documentId>str1234</documentId>
<documentTitle>str1234</documentTitle>
<dateCreated>str1234</dateCreated>
</docProperties>
</document>
</documents>
</folder>
</objectStore>
</addml>
As you can see above document tag can appear many times. all the values I will be getting from variables like (String documentID = "1234"). I need help in how to loop the elements and construct the above xml in java.
Any help is much appreciated.
Thanks, Mark
use DOM parser. consider
http://www.mkyong.com/java/how-to-create-xml-file-in-java-dom/
and
Xml file generator in java
i have a XML file in : /res/xml/countries.xml
and also i have a view with editText inside.
i want to search that text (users should type in editText) in my countries.xml file!
here is my xml file :
<?xml version="1.0" encoding="utf-8"?>
<countries>
<country>
<name>United State</name>
</country>
<countries>
If you want to read a whole document, use XML Parser, like Pull already mentioned. If you only want to pick out only one or few certain things, I would suggest XPath. Here is a good Tutorial on how to use XPath in Java.
First you need to parse that xml file containing the countries name. Store list of countries in any arraylist and then write any search algo to search the text found from that edittext.
Try this xpath tutorial...
You will have good learning experience...
This tutorial explain clearly how to parse an XML file : XML parser

I want to parse XML file using SaxParser. I'm trying to fetch the data associated to a tag or its attributes. The XML is in the following format.
<con>
<fig>
<abc>
<name xyz="">
<id>2</id>
</name>
</abc>
</fig>
</con>
I tried with couple of example but not succeeded in the fetching the data, I am requesting you to provide me any suggestion or and working example to increase my knowledge on parsing using SAX.
Use a DOM parser as your xml is very small and its easy to get what you are asking for.
There are my example and help available online, Please Google your question before posting on the stack over flow from next time.
Please check the following links which has good example for saxParsing

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.

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.

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.

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">

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.
I have this job in Talend that is supposed to retrieve a field and loop through it.
My big problem is that the code is looping through the XML fields but it's returning null.
Here is a sample of the XML:
<?xml version="1.0" encoding="ISO-8859-1"?>
<empresas>
<empresa>
<imoveis>
<imovel>
[-- some fields -- ]
<fotos>
<nome id="" order="">photo1</nome>
<nome id="" order=""></nome>
<nome id="" order=""></nome>
<nome id="" order=""></nome>
</fotos>
</imovel>
[ -- other entries here -- ]
</imoveis>
</empresa>
</empresas>
Now using the tExtractXMLField component I am trying to get the "fotos" element.
Here is what I have in the component:
I have tried to change the XPath query and the XPath loop query but the result is either I don't loop through the field or I get the null in the value field in the tMap.
Here is an image of the job:
You can see that I have retrieved 4 items from the XML but what I get is null in the "nome" field. There must be something wrong with the XPath but I can't seem to find the problem :(
Hope someone can help me out. Thanks
Notes: I am using talendv4.1.2 on ubuntu 10.10 64bit
If you want to loop on <nome> nodes your Loop XPath Query has to be
"/empresas/empresa/imoveis/imovel/fotos/nome"
and foto_nome XPath Query something like
"text()"
Take care: I also corrected an error in your XML that could bring issues (</imoveis> missing the "s").
There are two ways to go about it. One way is to use directly XMLinput and the instructions that bluish mentioned.
The other way is to continue on the path that you chose. In the XMLinput, make sure that your Loop XPath query is set to "/empresas/empresa/imoveis/imovel/fotos" and that you pass through the fotos element with the Get Nodes option checked. The XPath Query of your fotos element should be "../fotos" or ".".
Your extractXMLField component looks to be well configured.
Also, I don't know what tSetGlobalVar does in your design, but make sure it doesn't affect the fotos element that you're trying to pass through.
I have made a test job, this will help you definitely. If I'm not wrong you want to get all the "nome" under the "fotos" tag.
Try to change your loop xpath to the top level in the file, "empresas". Sometimes that works for me, also I have seem the "?xml version="1.0" encoding="ISO-8859-1"?" tag cause problems before, you could try to remove that.
Also make sure that the encoding is set correctly in the tFileInputXML.
I think you are confusing reading XML and extracting XML from XML.
Reading XML:
If the part of XML you have provided is the file readed by you tFileInputXML you don't need tExtractXMLField, just configure the tFileInputXML as this:
set the xpath loop to the <nome> elements, like this "//nome"
add 3 columns in the tFileInputXML component id, order and content
get content column with xpath query "."
get id value with xpath query "#id"
get order value with xpath query "#order"
Extracting XML from XML:
That is the goal of the tExtractXMLField component:
It allows to parse XML data contained in a database column or another XML document as if it was itself a data flow.
To put it in a nutshell, tExtractXMLField create a flow of data from a column record containing XML.
It is very useful when parsing soap query result: server reply is usually provided as xml, like this one:
<arg2>
<![CDATA[
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<exportInscriptionEnLigneType>
<date>2015-04-10</date>
<nbDossiers>2</nbDossiers>

<dossier>
<numOrdre>2</numOrdre>
<identifiantDossier>BBBBB</identifiantDossier>
</dossier>
</listeDossiers>
</exportInscriptionEnLigneType>
]]>
</arg2>
In XML above, arg2>element contains an XML document that you may need to parse.
tExtractXMLField has been created for this purpose.
I've written a tutorial on how to achieve this work, please have a look here "how to extract xml from xml". It is in french but screenshots may help understanding the few comments provided.
Hope it will help.
