protected Instruction createInstruction(Configuration instruction) throws ConfigurationException {
try {
String property = instruction.getAttribute("property");
String namespace = instruction.getAttribute("namespace", "DAV:");
XPath xPath = XPath.newInstance(instruction.getAttribute("xpath"));
return new Instruction(xPath, PropertyName.getPropertyName(property, namespace));
} catch (JDOMException e) {
throw new ConfigurationException("Could not create xPath from given attribute", instruction);
}
}
seems to require a namespace or it used the default "DAV:" namespace so I changed the xpath instructions to
<instruction namespace="http://xmlns.idega.com/com.idega.block.article"; property="headline" xpath="/article/headline" />
...
and the xml to (just testing hope there isn't a real need): <article xmlns:I="http://xmlns.idega.com/com.idega.block.article";> <I:headline>Header</I:headline> <I:teaser>Teaser</I:teaser> <I:body>Body</I:body> <I:author>Author</I:author> <I:source/> <I:comment>Comment</I:comment> </article>
But sadly it behaves the same way....

I think the problem might be different. It's just some time ago that I've written the SimpleXMLExtractor thing. If I find the time I'll look at it tomorrow. My first guess would be that it was developed using a different version of jdom.
Something might have changed as Slide was updated to jdom1.0 AFAK.

Nope...same deal. The "compiled" path for that example is /child::article/child::headline and propertyValue is still null.

It may be simpler than you think!
Try this:
"/article/headline"
This should return the value of article/headline, which in your example
would be "Header". I hope?

The problem is that I trying to get the SimpleXMLExtractor to extract those values as properties for the Lucene index but this code in SimpleXMLExtractor always returns "propertyValue" as null.
public Map extract(InputStream content) throws ExtractorException {
Map properties = new HashMap();
try {
SAXBuilder saxBuilder = new SAXBuilder();
Document document = saxBuilder.build(content);
for (Iterator i = instructions.iterator(); i.hasNext();) {
Instruction instruction = (Instruction) i.next();
XPath xPath = instruction.getxPath();
List nodeList = xPath.selectNodes(document);
Object propertyValue = filter(nodeList, instruction);
if (propertyValue != null) {
properties.put(instruction.getPropertyName(),
propertyValue);
}
in Domain.xml I have the third try...I obviously know nothing about
XPath ;)
<!-- Extractor configuration -->
<extractors>
<!--XML extractors-->
<extractor
classname="org.apache.slide.extractor.SimpleXmlExtractor" uri="/files">
<configuration>
<instruction property="headline"
xpath="/article/headline[1]" />
<instruction property="teaser"
xpath="/article/teaser[1]" />
<instruction property="body" xpath="/article/body[1]"
/>
<instruction property="author"
xpath="/article/author[1]" />
<instruction property="source"
xpath="/article/source[1]" />
<instruction property="comment"
xpath="/article/comment[1]" />
</configuration>
</extractor>
...

A assume your examples didn't work... The xpath expression looks correct to me. What exactly is the encountered problem? Cheers, Daniel

Anyone know what is the XPath to the content of the xml tags in this
example? I've tried some paths but I'm barely a novice in XPath...
<article xmlns="http://idega.com/block/article/bean";> <headline>Header</headline> <teaser>Teaser</teaser> <body>Body</body> <author>Author</author> <source/> <comment>Comment</comment> </article>
I tried e.g. : "/article/headline[1]/text()" and just "/article/headline/text()"
