Subject [jira] Updated: (ODE-281) XPath functions for RESTful BPEL: combineUrl, composeUrl
Date Tue, 13 May 2008 03:06:55 GMT

     [ https://issues.apache.org/jira/browse/ODE-281?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alexis Midon updated ODE-281:
-----------------------------

    Description: 
Provide 2 new Xpath functions as described in the ODE wiki:

__combineUrl(base, relative)__
----------------------------------------------------
Takes the relative URL and combines it with the base URL to return a new absolute URL. If
the relative parameter is an absolute URL, returns it instead.

__composeUrl(template, [name, value]*)__
__composeUrl(template, pairs)__
----------------------------------------------------
Expands the template URL by substituting place holders in the template, for example, ('/order/{id}',
'id', 5) returns '/order/5'. Substitute values are either name/value pairs passed as separate
parameters, or a node-set returning elements with name mapping to value. The functions applies
proper encoding to the mapped values. Undefined variables are replaced by an empty string.
Compliant with the URI Template spec [1].


__expandTemplate(template, [name, value]*)__
__expandTemplate(template, pairs)__
----------------------------------------------------
Same behavior as composeUrl except that undefined variables are *NOT* replaced by an empty
string. The corresponding expansion pattern is not replaced. Meaning that the function may
return a template.

proper encoding to the mapped values, and with incomplete mapping may return a new URL template.
