I'm going to assume Rick means a hyperlink to a graphic, such as an <IMG SRC="..."/> element....

In the simple case, it could be as easy as

<xsl:template match="foo">
<!-- copying the foo since Rick didn't tell us otherwise -->
<xsl:if test=".='?'">
<!-- testing if the value of the current node is equal to the string '?' -->
<img src="questionmark.jpg"/>

But this is assuming many things. Things are trickier if you need to worry about strings floating in other strings (not just testing for and replacing entire strings) -- then you will have to recurse over your text node, as Jeni does when replacing a string with another (Rick, see Also whitespace might be a problem: you may have to work around that. Then too, there are tricks one can use (not shown here) to make the solution more scalable. But mainly, Rick hasn't said if, when and what *else* happens to <foo> elements or the text inside them, which he might have to account for.

I hope that helps,

What do you mean, "with a graphic"?  Do you want a hyperlink to a graphic?
Do you want the graphic to be inserted using base64 encoding?  So you want
to insert an svg graphic? ...
