tdt:concat()

This function is similar to the str:concat function defined in EXSLT. It takes a node set and a string separator and returns the concatenation of the string values of the nodes in that node set.

Note:

Do not confuse tdt:concat() with standard XPath concat().

Signature

<string> tdt:concat(<node-set>[, <string>])

<node-set>	Strings to be concatenated. If the node set is empty, an empty string is returned.
<string>	String separator (can be an empty string). If no separator is defined, the strings are concatenated without a separator.

Example

Data source

<data> <message> <word>We</word> <word>are</word> <word>having</word> <word>fun</word> </message> </data>

Data template

<data> <sentence>?</sentence> </data>

Data transformation

<tdt:rule path="/data/sentence"> <tdt:value key="text()">tdt:concat(/data/message/word, ' ') </tdt:value> </tdt:rule>
