I have created sitemap using the com.redfin.sitemapgenerator jar, now I want to add nodes i.e the urls in the urlset at run time, I have checked that the sitemap already exists or not but now I am unable to append to the already existing sitemap.xml file.`public String searchforques()
throws IllegalArgumentException {
// TODO Auto-generated method stub
System.out.println("calledd");
WebSitemapGenerator sitemapGenerator = null;
WebSitemapUrl sitemapUrl = null;
File file=new File("C:\\sitemap\\sitemap.xml");
try {
if(!file.exists())
{
sitemapGenerator = WebSitemapGenerator
.builder("http://www.testing.com", new File("C:\\sitemap"))
.gzip(false).build();
/*------------------------------------------*/
try {
sitemapUrl = new WebSitemapUrl.Options(
"http://www.testing.com/#!dashboard1")
.lastMod(new Date()).priority(1.0)
.changeFreq(ChangeFreq.HOURLY).build();
System.out.println("-----------");
System.out.println("sitemapUrl :: "+sitemapUrl.getUrl());
sitemapGenerator.addUrl(sitemapUrl);
} catch (MalformedURLException e) {

e.printStackTrace();

sitemapGenerator.write();
// this will configure the URL with lastmod=now, priority=1.0,
// changefreq=hourly
// You can add any number of urls here
return "";
}
But my else part is not working it directly goes to server fail.
I am working on java with gwt.
So, any one could help to add dynamically the nodes(urls) in the urlset at runtime.

I have created a program to convert text to xml by using ReverseXSL API.
This program is to be executed by an application by calling static method (static int transformXSL).
I am able to execute and produce output with running from Eclipse. However, When I ran program (jar) by using application it stuck somewhere and I couldnt find anything.
Then, I debugged by "Debug as...-> Remote Java Application" in Eclipse from Application and found "InvocationTargetException" at ClassLoaders.callStaticFunction.

I need help understanding why the XML String does not convert into a CSV file. Why is the CSV Resut always empty?

Best way is to use XSLT to "transform" the XML to CSV --> Can someone give me hint?
Consider to load the XSLT code from a file or URI (instead of from a string) as otherwise your approach of doing <xsl:param name="fields" select="document('')/*/xsl:variable[#name='fieldArray']/*" /> where document('') tries to pull in the XSLT code again is likely to fail, unless you set up a special resolver.
I have an string which I am attempting to extract values from, for convenience I thought that converting the string to a Document and then parsing the xml would be the best way to do this but I am running into all sorts of problems! The string looks like:
<Messagexxx>
<Unit>
<contact>0</contact>
<text>Test Content</text>
<date>09-Sep-14 13:56</date>
<subject>Test Title</subject>
</Unit>
</Messagexxx>
Can someone point me in the correct way to achieve my goal of reading the values from the tags .
I have attempted using the following snippet but I all the values in the array are
null! Document xml = null; Node T = null; try { xml = stringToDom(message); T = xml.getLastChild(); } catch (SAXException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (ParserConfigurationException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } if(xml.getFirstChild() != null){ }
When you write your string to a text file, you can first parse it:
private Document parse(String filename){
Document doc = null;
try {
DOMParser parser = new DOMParser();
parser.parse(filename);
doc = parser.getDocument();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return doc;
}
and then you read all text elements out of this document:
public void extract (Document doc){
Node root = doc.getDocumentElement();
for (int i = 0; i< root .getChildNodes().getLength(); i++){
Node child = root.getChildNodes().item(i);
System.out.println(child.getTextContent());
}
}
Use JAXB lib : https://jaxb.java.net/
Create your model from your XML and to read :
JAXBContext jaxbContext = JAXBContext.newInstance(YourModel.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
StringReader reader = new StringReader("xml string here");
YourModel yourModel= (Person) unmarshaller.unmarshal(reader);
After your can use the object "YourModel" to read your value.
This is a very simple way to get node values when you know the node names, and they don't repeat:
String getXmlNodeValue(String xmlString, String nodeName){
int start = xmlString.indexOf("<"+nodeName+">") + nodeName.length() + 2;
int end = xmlString.indexOf("</"+nodeName+">");
return xmlString.substring(start, end);
}
I am reading in an XML file, and trying to return the values in another class using Java. In the XML Reader I read in the values from the XML file. I'm not quite sure how to do this. Any help would be appreciated.
public class XMLReader {
public static List<String> load()
{
try{
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse (new File("C:/adapters.xml"));
doc.normalize();
NodeList rootNodes = doc.getElementsByTagName("adapters");
Node rootNode = rootNodes.item(0);
Element rootElement = (Element) rootNode;
NodeList adaptersList = rootElement.getElementsByTagName("class");
for(int i=0; i<adaptersList.getLength(); i++){
Node theAdapter = adaptersList.item(i);
Element adpElement = (Element) theAdapter;
System.out.println("This is: " + adpElement.getTextContent());
}
}catch(ParserConfigurationException e){
e.printStackTrace();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
}
public class AdapterLoader {
public static List<AbstractAdapter> loadAllAdapters()
{
List<AbstractAdapter> allAdapters = new ArrayList<AbstractAdapter>();
List<String> adapterClasses = XMLReader.load();
for (String className : adapterClasses)
{
try {
Class adapters = Class.forName(className);
AbstractAdapter adp = (AbstractAdapter) adapters.newInstance();
allAdapters.add(adp);
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return allAdapters;
}
}
Instead of printing it to console
System.out.println("This is: " + adpElement.getTextContent());
add this to a List and return that instead of
return null;
