How to add children to children using jsoup document

I am trying to create the following example.

<body> <resources> <string-array name="mytest"> <item number="1"> <name>Testname</name> </item> <item number="2"> <name>blaat..</name> </item> </string-array> </resources> </body>

I try this by doing the following:

 FileInputStream fis = openFileInput("test1.xml"); Document doc = Jsoup.parse(fis, "UTF-8", ""); Node node = doc.getElementsByTag("item").get(getPosition()); fis.close(); fis = openFileInput("test2.xml"); Document doc2 = Jsoup.parse(fis, "UTF-8", ""); fis.close(); Elements test = doc2.getElementsByTag("resources"); if(test.size() < 0){ fis = openFileInput("test2.xml"); doc2 = Jsoup.parse(fis, "UTF-8", ""); fis.close(); doc2.appendElement("resources").parent(); FileOutputStream os = openFileOutput("test2.xml", Context.MODE_PRIVATE); os.write(doc2.toString().getBytes()); os.close(); fis = openFileInput("test2.xml"); doc2 = Jsoup.parse(fis, "UTF-8", ""); fis.close(); doc2.appendChild(doc2.appendElement("string-array").attr("name", "mytest")).parent(); os = openFileOutput("test2.xml", Context.MODE_PRIVATE); os.write(doc2.toString().getBytes()); os.close(); System.out.println("Created file\n"); } doc2.appendChild(node); FileOutputStream os = openFileOutput("test2.xml", Context.MODE_PRIVATE); os.write(doc2.toString().getBytes()); os.close();

And now I get the following:

 <!-- test1.xml (input) --> <resources> <string-array name="firsttest"> <item number="1"> <name>Testname</name> </item> <item number="2"> <name>blaat..</name> </item> <item number="3"> <name>Next item</name> </item> </string-array> </resources> <!-- test2.xml (output)--> <body> <resources></resources> <string-array name="mytest"></string-array> <item number="1"> <name>Testname</name> </item> <item number="2"> <name>blaat..</name> </item> </body>

Can someone tell me what I'm doing wrong, and maybe give some examples of how to do this?

Thanks in advance

EDIT: To get a little more detailed: I want to copy some elements from test1.xml to test2.xml. So basically the user selects a listitem that points to the number in text1.xml (position number), and this element should then be copied to (ITEM HERE

Jsoup is usually used to parse html, not xml, although they have the same structure. By default, Jsoup parses something, then completes it inside <html><body> ... </body></html> .

An example for your purpose:

 import org.jsoup.nodes.*; Document doc = Jsoup.parse(""); // clear <html><body></body></html> doc.html(""); Element e = doc.appendElement("body").appendElement("resources"); e = e.appendElement("string-array"); e.attr("name", "mytest"); for (int i = 0; i < 10; i++) { Element sub = e.appendElement("item"); sub.attr("number", Integer.toString(i)); sub.appendElement("name").text("blahh"); }

This will not solve your exact problem, but you must understand it. I pretty much create test2.xml as a new document. So, if it exists with information in it, you will have to get around this.

  String html = "<resources>" + "<string-array name=\"firsttest\">" + "<item number=\"1\">" + "<name>Testname</name>" + "</item>" + "<item number=\"2\">" + "<name>blaat..</name>" + "</item>" + "<item number=\"3\">" + "<name>Next item</name>" + "</item>" + "</string-array>" + "</resources>"; Document test1 = Jsoup.parse(html); Document test2 = Jsoup.parse(""); test2.body().append("<resources>"); test2.select("resources").append("<string-array name='mytest'>"); test2.select("[name=mytest]").append(test1.select("item[number=1]").toString()); test2.select("[name=mytest]").append(test1.select("item[number=2]").toString()); System.out.println(test2.body().children());

Here is the result:

  <resources> <string-array name="mytest"> <item number="1"> <name> Testname </name> </item> <item number="2"> <name> blaat.. </name> </item> </string-array> </resources>
