Subject: Re: [xsl] Help to construct a loop From: henry human <henry_human@xxxxxxxx> Date: Sat, 29 Dec 2007 23:22:34 +0100 (CET) |
Actually this is a bpel (business process execution language) process which I am working on. Bpel itself is xml based and allows using xsl functions. For e. in the bpel specification 2.0 there is possible to build loops with for-each, while etc. In my case my bpel process becomes this string from a web service and I will to handle this string within the bpel process f.i. in a while loop. As I mentioned in the sample the string which the bpel process becomes from the web service has a colon which I think enables to inspect the string based on the token and build the substrings. Unfortunately there is no a specific list or forum for the bpel language specified issues. <while name="lookForSubstrings"> <!this is what I dont know, how to build the condition in xsl for a loop --> <condition> substring-before($myString, ':') </condition> <sequence name="sequence2"> <if name="extractSubstrings"> <assign name="SendOutputToClient" > ........... </assign> <else> <assign name="displayElse"> ........... I hope it makes the problem clearer! henry --- Abel Braaksma <abel.online@xxxxxxxxx> schrieb: > Hi Henry, > > Without seeing your source and how your $myString is > formed, this is > rather hard to answer.
