I am not sure which processors support similar, but DataPower
XSLT processor provides (proprietary) extension functions
dp:parse() ("Parses a well-formed XML document to produce a
node set") and its reverse dp:serialize() ("Sends the output
for a specified node set as a byte stream").
These allow for a really short implementation for this problem:

$ curl --data-binary @siddi.xml http://dp1-l3.boeblingen.de.ibm.com:2051 ;
echo ; echo
<?xml version="1.0" encoding="UTF-8"?>
<book><key>key1</key>, <key> k<i>e</i>y2</key>, <key> key<b>3</b></key>,
<key> <u>ke</u>y4</key>, <key> <b>k</b>ey<i>5</i></key></book>

        <xsl:if test="position()!=last()">, </xsl:if>

For those following this thread on XSL-List, the LinkedIn parallel
thread with the same problem was augmented with new requirements not
included in the original post.  Apparently, the commas are the
overarching determinants in the grouping of the information ... not
commas and elements as guessed at for the first time around.

This changes the problem from a simple iteration into a more
elaborate grouping.  A complete solution is below for readers of this
archive who may have a similar need of working with portions of text nodes.
