When you receive an XML response from
Adobe Connect, you need to be able to parse it to extract the XML
elements you need.
If you are working in a language such as Java™,
with an XML parser (such as Xerces or JDOM) installed, you can parse
through an XML response, select values from nodes, and then use
those values.
Use XPath to parse a response
Write a method that calls one or more actions.
Create an instance of the XPath class so that you can use the XPath
expressions. Call the actions, read the XML response, and use XPath
syntax to select the values you need:
public String scoUrl(String scoId) throws XMLApiException {
try {
Element e = request("sco-info", "sco-id=" + scoId);
if(!(codePath.valueOf(e).equalsIgnoreCase("ok")))
return "";
XPath xpath = XPath.newInstance("//url-path/text()");
String path = ((Text) xpath.selectSingleNode(e)).getText();
e = request("sco-shortcuts", null);
xpath = XPath.newInstance("//domain-name/text()");
String url = ((Text) xpath.selectSingleNode(e)).getText();
return url + "/" + path.substring(1) + "?session=" + breezesession;
} catch (JDOMException jde) {
throw new XMLApiException(PARSE_ERROR, jde);
}
}
You can also use string pattern matching to check
for a status code of
ok
. A successful action always
returns this response:
<?xml version="1.0" encoding="utf-8" ?>
<results>
<status code="ok" />
</results>
You can check the response for the
pattern
ok
or
code="ok"
.
