How to change inner content of HTML tag using HTMLDocument?

Question

I want to change the inner content of an HTML tag from a HTMLDocument. The tag is like
<span id ="id1">Replace me</span>.
So I want to change the text "Replace me" inside the span tag and replace it with an other text.
I can get the span element using
HTMLDocument.getElement("id1")
I have tried many things with the Element instance i got from getElement. But I find no way to change the inner content of the HTML element. Any ideas?

If I use JDK 1.5 the SPAN tag works, so I checked the core of the problem which is inserting HTML code in an HTML tag.
setInnerHTML works fine for block tags like DIV but not if the tag is a leaf element like the SPAN tag. I have tried to use the following code for leaf elements:
Element elem = m_htmlDocument.getElement(id);
int nStartOffest = elem.getStartOffset();
int nEndOffset = elem.getEndOffset();
int nLength = nEndOffset - nStartOffest;
m_htmlDocument.replace(nStartOffest, nLength, html, elem.getAttributes());
This works, but only if the new HTML string does not contain HTML tags like a link <href..... >. If the string contains HTML tags the replace method masks all characters like < or >. So the link is not shown as link in the HTML page but as HTML text.
The next thing I have tried is using
m_htmlDocument.setOuterHTML(elem, html);
This works too but it replaces the whole original HTML element like the SPAN tag.
So there is still the question how to insert HTML text into a leaf Element in a HTMLDocument.
