How to disable/avoid Ampersand-Escaping in Java-XML?

i need to create something like: ∧(in the xml-file) and the problem is, that the java technique i am using convertes it to &#8743; what doesn´t work for me. i need it in the first format. so, the question is, is there a way to escape it in some way or whatever to get it like that: ∧? for the exporting i am using the same method as here: link

Please show us your code fragment, and we'll help you correct it. — Sergey Kalinichenko, Nov 06 '12 at 15:28
i am using the method i have linked. -__- this project is big. but it works in the same way as on the linked page. i am using this: `tag.setAttribute("defaultText", "∧");` — immerhart, Nov 06 '12 at 15:41

Is this what you want?

    DocumentBuilderFactory f = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = f.newDocumentBuilder();

    Document d = builder.newDocument();
    Element root = d.createElement("root");
    d.appendChild(root);
    root.setTextContent("this text contains the \u2227 character");

    Transformer t = TransformerFactory.newInstance().newTransformer();
    t.setOutputProperty(OutputKeys.ENCODING, "US-ASCII");
    t.setOutputProperty(OutputKeys.INDENT, "yes");
    t.transform(new DOMSource(d), new StreamResult(System.out));

which produces

<?xml version="1.0" encoding="US-ASCII" standalone="no"?>
<root>this text contains the &#8743; character</root>

yeah, but i need it for a tag and not the text between the tags. perhaps it works there, also. i ll try it tomorrow! – immerhart Nov 06 '12 at 19:41
Huh? For a tag? Do you mean for an attribute? – forty-two Nov 06 '12 at 20:49
Well, it works the same for attributes. Try it! – forty-two Nov 06 '12 at 20:51
nice. will try it tomorrow... thanks – immerhart Nov 06 '12 at 20:52
OK, but now that you have 42 reputation, the time is ripe ;-) – forty-two Nov 06 '12 at 20:53
i don´t get what you mean :) can´t test it right now, because i do not have the project with me. but tomorrow. and if it works, i mark your answer... – immerhart Nov 06 '12 at 21:17
as you said. it works. so thank you! – immerhart Nov 07 '12 at 09:09

The way to do this is using &. Typically it works. If it does not work for your please post some code snippets.

Or in other words: when parsing an XML document which contains "∧" with a proper XML parser will return "∧" again. – Puce Nov 06 '12 at 15:35
now it doesn´t work. if it would work, i wouldn´t ask. `∧` gets to `&#8743;` – immerhart Nov 06 '12 at 15:36
And yet in other words: an XML document which contains "∧" is not a valid XML document, AFAIK. – Puce Nov 06 '12 at 15:37
Please show the relevant code, as suggested. – Puce Nov 06 '12 at 15:38
how the user should enter the sign that is not on the keyboard? `∧` is valid xml – immerhart Nov 06 '12 at 15:48
Yes, you are correct, it's valid: http://www.w3.org/TR/2006/REC-xml11-20060816/#sec-references Sorry for the confusion. – Puce Nov 06 '12 at 16:00

I think the issue is that you're trying to encode the XML by hand.

Try:

Convert the user input to Java String
Let the XML library take care of converting from Java String to XML String

this post is senseless XD. how to pass something other than a string to the `tag.setAttribute()` method than a string? – immerhart Nov 06 '12 at 19:49
@immerhart according to forty-two's response, "∧" in XSD is equal to "\u2227" in Java. So, make sure you use the Java character encoding, not the XSD character encoding. – Puce Nov 07 '12 at 08:46

You could try:

Document doc = documentBuilder.newDocument();
Element root= doc.createElement("root");
doc.appendChild(root);

Document newDoc = documentBuilder.parse(new InputSource(new StringReader("<element defaulttext=\"&#8743;\">some text or XML</element>")));

Element newElement = newDoc.getDocumentElement();
Node node = doc.importNode(newElement, true);

root.appendChild(node);
