Java: Error while parsing XML document as text

Question

I'm trying to parse XML document as String by using the following

Document parse = DocumentBuilderFactory.newInstance().newDocumentBuilder()
                .parse(new InputSource(new StringReader(xmlFile)));

but I'm getting this error

[Fatal Error] The entity "Ouml" was referenced, but not declared.

I tried escape and unescape xmlFile String using Apache StringEscapeUtils but still having errors

Its telling you theres something wrong with the xml, at an element named "Ouml". By the sounds of your question, you should be treating the file as a regular file (java.util.Scanner?) rather than using an xml parser? — ConMan

HTML 4.0 knows 252 predefined character-entities like Ö, ß etc.

XML on the other hand only has 5:

&lt;
&gt;

You can't use named character-entities from html other than those without defining them first.

So when using StringEscapeUtils make sure you use escapeXml() instead of escapeHtml4().
