So my first statement still holds, you need to parse the content into a tree, manipulate some nodes and export again as markup.

Wiki-syntax is nested, e.g. a table entry can be bold or a link!

No "object-oriented substrings" needed!

    But then I could not guarantee that the output is exactly the same as the input outside of the specific values being updated.

    DOM-tree<-->wiki-syntax is a one-to-many relationship, for example each of the following is a valid wiki-syntax representation of a table row containing 3 cells with the contents A, B, and C:

    |- | A || B || C

    |- | A | B | C

    <tr> <td>A</td> <td>B</td> <td>C</td> </tr>

    Also, I doubt that writing a full-blown parser and serializer would result in less work and less code than a regex-based solutions supported by linked substrings.

      But then I could not guarantee that the output is exactly the same as the input outside of the specific values being updated.

      :) Sure you could. While HTML DOM doesn't guarantee same representation, there is no reason your DOM couldn't -- hey, if PPI can do it, you can too :) whitespace can be significant if you make it so
