Subject: Using XSLT 2.0 to define custom functions
Author: Shyam V

Hi,

I am looking to create a function using XSLT to replace multiple typesetter tags (print tags - essentially string patterns) with their HTML tag version. In order to do this, I could use the replace function over and over again

for example:
replace (replace (string, pattern1, replace1), pattern2, replace2) ... and so on

This could become extremely diffuclt to debug and maintain. So, I was creating custom functions using XSLT 2.0 to create the same feature by calling multiple custom function (each replacing a single type of pattern)

For example

<xsl:value-of select="mynms:processSubscript($baseString)"/>
<xsl:value-of select="mynms:processBold($baseString)"/>
ETC

When I do this, the replaced string appends itself to the original string. So I end up having the same string concatenated onto itself multiple times (depending on the number of functions I call)

Resulting text looks like this

"my stringmy stringmy stringmy stringmy string"

Does someone know how I can call multiple custom functions, with the result of the first function passed to the next function ?

Hope you can help.

Thanks in advance.
