transform() fails for DOMSource but succeeds for StreamSource 2006-12-27 - By Ziv Ben-Eliahu
Hi There.
I have a similar problem - fails for DOMSource but succeeds for
StreamSource - but failure is not an error, it is a different output.
I have the following XML:
<apple xmlns="http://purl.oclc.org/NET/JSX/0.3/Apple">
<shop type="happy-days">
<owner name="Jhon" type="big"/>
</shop>
<order name="GooGoo" type="org.goo" />
</apple>
I have two parsers - an identity-transformer and a xsl-transformer :
Transformer tfCopy = javax.xml.transform.TransformerFactory
.newInstance().newTransformer();
Transformer tf = javax.xml.transform.TransformerFactory
.newInstance()newTransformer(
new StreamSource(new File("Apple.xsl")));
I have three source type - by stream, builder-parsed, builder-created:
Document parsedDoc = builder.parse(new File("apple.xml"));
DOMSource parsedSource = new DOMSource(parsedDoc);
StreamSource streamSource = new StreamSource(new File("apple.xml"));
DOMSource builtSource = new DOMSource(build()); // build() is a manual
build of the parsed document
When I use the identity-transformer the results are the same:
tfCopy.transform(streamSource, new StreamResult(new
File("d:/streamed.xml")));
tfCopy.transform(builtSource, new StreamResult(new
File("d:/built.xml")));
tfCopy.transform(parsedSource, new StreamResult(new
File("d:/parsed.xml")));
When I use the XSL-based-transformer, results are completely different.
tf.transform(builtSource, new StreamResult(new
File("d:/built.html")));
tf.transform(parsedSource, new StreamResult(new
File("d:/parsed.html")));
tf.transform(streamSource, new StreamResult(new
File("d:/streamed.html")));
I won't include them since they are long, but to sum up:
The stream-source gave the expected results.
The parsed-dom-source (from the same file as the stream-source) gave bad
results - its like the Document was not recognized.
The manually-built-dom-source gave the expected results.
Question: how come identity-transformer worked fine with the parsed DOM
and a xsl-transformer did not?
My current solution is:
Use the identity-transformer to copy from the parsed-dom to a
result-dom. Then take the node from the result-dom. The XSL-transformer
works fine with that node.
Thank you for your help,
Ziv.
