Simple question, but can't find the answer anywhere.
I want to load an XML config file into memory, and then access its element and attribute values from flowscript using XPath. It will be a different file for each page request (these parameters will be used to help create the response).
Essentially, I'd like to create something like this in the flowscript:
function setParams(uri) { cocoon.context.setAttributes("params", -config file data here-); }
Here's the config file (example):
<?xml version="1.0" encoding="UTF-8"?> <params> <color>blue</color> <size>XL</size> <quantity>5</quantity> </params>
No time to give you a thorough answer, but what you can do is:
(a) read your config file into a DOM document
Can't tell you this off the top of my head
(b) Create a JXPathContext, using your DOM document:
var jx = Packages.org.apache.commons.jxpath.JXPathContext.newContext(myDomObject);
jx.setLenient(true);
(c) Use the JXPathContext to access your objects.
var color = jx.getValue("/params/color");
It isn't that hard, but if you do a lot of it, you might like to wrap this in a small Java class so that you can:
var jx = MyJXPathObject.getConfigFile("myconfigfile.xml");
var color = jx.getValue("/params/color");
