If I write <xmlElement> in a javadoc, it does not appear, because tags have special functions on formatting texts.
How can I show this chars in a javadoc?
You can use < for < and > for > .
Recent versions of JavaDoc support {@literal A<B>C}; this outputs the content correctly (escaping the '<' and '>' in the generated HTML).
See http://download.oracle.com/javase/1.5.0/docs/guide/javadoc/whatsnew-1.5.0.html
Considering XML is actual code, I believe XML snippets in Javadoc are better suited for the {@code A<B>C} tag rather than the {@literal A<B>C} tag.
The {@code } tag uses a fixed-width font which makes its content standout as actual code.
Escape them as HTML: < and >
You only need to use the HTML equivalent for one of the angle brackets. The < can be represented as either < or <. Here's a sample taken from real Javadoc:
<pre>
<complexType>
<complexContent>
<restriction base="{http://www.w3.org/2001/XMLSchema}anyType">
<sequence>
[...]
This displays as:
<complexType>
<complexContent>
<restriction base="{http://www.w3.org/2001/XMLSchema}anyType">
<sequence>
If you set maven up to use markdown, you can just surround it with backticks.
`A<B>C` reads a bit nicer than {@code A<B>C}
