This function parses the main part of the content, i.e., the content which has been entered in the Rich Text Editor. The function is responsible for the fact that the content is not rendered exactly as it was entered in the RTE. Some default parsing rules are implemented in the core, like parsing link tags via typolink function.

You can also use parseFunc for your own processing. In the following example, every occurrence of "COMP" is replaced by "My company name":

page.stdWrap.parseFunc.short {
   COMP = My company name

The various possibilities of changing the default behavior can be found by using the TypoScript object browser. All possibilities of how parseFunc can alter the rendering can be found in the TypoScript Reference.
