Ive written some code that creates an XML file from my System Properties in java. It works exactly how I want it to but I really (really) dont like how I ended up just using like 5 if statements to get it to work since I noticed none of the properties go beyond 4 delimited substrings anyways.
Id much prefer using an iterator and some kind of hasNext() method to continue appending onto elements until the end of the string but I couldn't work anything out.
I couldn't find a way to append the newest tag onto the last one in a loop/ add the value to the end of the elements.
This is what I currently have as a quick fix to get the program running.
Document doc = docBuilder.newDocument();
Element rootElement = doc.createElement("JAVA");
doc.appendChild(rootElement);
Iterator it = hm.entrySet().iterator();
while (it.hasNext())
{
Map.Entry entry = (Map.Entry) it.next();
String keyString = (String)entry.getKey();
String val = (String)entry.getValue();
java.util.List<String> sa = Arrays.asList(keyString.split("\\."));
Iterator ait = sa.iterator();
Element tag = doc.createElement((String) ait.next());
rootElement.appendChild(tag);
Element tag2 = null;
Element tag3 = null;
Element tag4 = null;
Element tag5 = null;
while(ait.hasNext())
{
if(ait.hasNext())
{
tag2 = doc.createElement((String)ait.next());
tag.appendChild(tag2);
if(!ait.hasNext())
tag2.appendChild(doc.createTextNode(val));
}
if(ait.hasNext())
{
tag3=doc.createElement((String)ait.next());
tag2.appendChild(tag3);
if(!ait.hasNext())
tag3.appendChild(doc.createTextNode(val));
}
if(ait.hasNext())
{
tag4=doc.createElement((String)ait.next());
tag3.appendChild(tag4);
if(!ait.hasNext())
tag4.appendChild(doc.createTextNode(val));
}
if(ait.hasNext())
{
tag5=doc.createElement((String)ait.next());
tag5.appendChild(tag5);
if(!ait.hasNext())
tag5.appendChild(doc.createTextNode(val));
}
}
}
Transformer transformer = null;
TransformerFactory transformerFactory = TransformerFactory.newInstance();
try
{
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File("XMLtester"));
transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
transformer.transform(source, result);
} catch (TransformerConfigurationException e)
{
e.printStackTrace();
} catch (TransformerException e)
{
e.printStackTrace();
}
catch(NullPointerException e)
{
System.out.println("ERROR: " + e.toString());
}
System.out.println("File saved!");
If anyone has any ideas on how to make this a little more flexible or elegant so as to take in any number of delimited substrings id appreciate it.
I think this is what you want.
Element destination = rootElement;
Element tag = null;
while (ait.hasNext()) {
tag = doc.createElement((String) ait.next());
destination.appendChild(tag);
destination = tag;
}
destination.appendChild(doc.createTextNode(val));
Example output:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

I have an XML that uses Map* , see below. I want to assign some values to an array (usrHoey).
example.
Assign "String_2" to Variable kode
Assign 2 to Variable prosentsats
How do I accomplish this in java using XPath. See below java code, area to look at is "// usrHoey ************************* ". The previous variable "ankomstDato" work fine.
XML file(xyx.xml)
<?xml version="1.0" encoding="UTF-8"?>
<map xmlns="http://www.w3.org/2005/xpath-functions">
<string key="ankomstDato">2020-08-03T09:24:40.486</string>
<map key="historikk">
<array key="usrHoey">
<map>
<string key="kode">string</string>
<number key="prosentsats">0</number>
</map>
</array>
</map>
</map>
Java code that is working well will other simple Nodes.

So this code uses the initial value digits after hash to start the counter.
Then it iterates through all the files in the folder.

And
/input12/bunny
/input12/bunny
/input12/bunny
/input12/bunny
in the the list Source values
surce value and the target value has link.. means first value of source is connected with first value of target.. 2nd value of source connected with 2nd value of target.

I'm trying to edit an XML file with Java, the thing is that I need to edit the content & replace them by what I want inside
(I want to replace some nodes that are in Deutsh into French
[for expample <fr>DE1</fr> into <fr>FR1</fr>])
I tried to use :
node.setTextContent(Value);
node.setNodeValue(Value);
But it doesn't work at all
Is there any other function that might work in editing these nodes below ?
Here's the code :
for (int i = memory; i < nodes.getLength(); i++) {
Node node = nodes.item(i);
if ((langu.equals(node.getNodeName()))) //langu = "fr"
{
test = node.getTextContent();
if(isCorrect()){}
else if ((manualTr.clickCount >= 0)
){
trash = test;
node.setTextcontent(Value);
// node.setNodeValue("Test");
memory += manualTr.clickCount;
manualTr.clickCount -= 1;
}
}
}
And here's the XML code :
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<titles>
<tome>
<de>DE1</de>
<fr>DE1</fr>
<en>EN1</en>
</tome>

<en>EN2</en>
</valhalla>
<vikings>
<de>DE3</de>
<fr>DE3</fr>
<en>EN3</en>
</vikings>
</titles>
Try this.. I am using setTextContent() to update a node value.

I created a simple class to create an XML document.
However, if I call the method more than once while creating a document of the same name the file does not overwrite.
How could I make the class automatically overwrite existing files of the same name?

Document doc = docBuilder.newDocument();
Element rootElement = doc.createElement(root);
doc.appendChild(rootElement);
for (int i = 0; i < elements.length; i ++) {
Element element = doc.createElement(elements[i]);
element.appendChild(doc.createTextNode(children[i]));
rootElement.appendChild(element);
}
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
File dir = new File(System.getProperty("user.dir"));
StreamResult result = new StreamResult(new File(dir + "\\XML\\" + name + ".xml"));
transformer.transform(source, result);
}
catch(ParserConfigurationException pce){
pce.printStackTrace();

I executed your code with the following statements:
public static void main (String[] args)
{
XMLCreater x = new XMLCreater();
String[] s = {"A","B","C"};
try
{
x.CreateXMLDoc("k","root",s,s);
x.CreateXMLDoc("k","root",s,s);
x.CreateXMLDoc("fakih","root",s,s);
}
catch (TransformerConfigurationException exception)
{ exception.printStackTrace(); }
}
And it nicely overwrites the existing files, no problems about overwriting, check it yourself.
I'll be honest here... I'm not able to replicate your problem. It works fine for me when I run this program multiple times in a for loop. Are you sure you didn't accidentally open the result file, thus locking it, before running your program?
If you are concerned of having multiple threads running your program at the same time, perhaps you can apply a synchronized block to prevent two threads trying to write the same file, like this:-
...
synchronized (XMLCreater.class) {
StreamResult result = new StreamResult(new File(dir + "\\XML\\" + name + ".xml"));
transformer.transform(source, result);
}
