I want to transform some xml using an xsl-file and output the result somehow (I’m using Android Api Level 8).
My current activity looks like this, but the transformer stays null.
LogCat throws an System.err with org.apache.harmony.xml.ExpatParser$ParseException, saying the xml is not well-formed, but I made sure it is.
I found a hint in LogCat that says SystemId Unknown just before the above error message.
What am I doing wrong?
import java.io.OutputStream;
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerFactoryConfigurationError;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import android.app.Activity;
import android.os.Bundle;
public class XsltTester extends Activity {
private static String TAG = XsltTester.class.getSimpleName();
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
Source xmlSource = new StreamSource(this.getResources().openRawResource(R.xml.source));
Source xsltSource = new StreamSource(this.getResources().openRawResource(R.xml.products));
TransformerFactory transFact = TransformerFactory.newInstance();
Transformer trans = transFact.newTransformer(xsltSource);
OutputStream output = new StringOutputStream();
StreamResult result = new StreamResult(output);
trans.transform(xmlSource, result);
} catch (TransformerConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (TransformerFactoryConfigurationError e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (TransformerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
This is the xml-file to be transformed (source.xml)
<?xml version="1.0"?>
<!-- <?xml-stylesheet href="beatle.xsl" type="text/xsl"?> -->
<person>
<name>
<firstname>Paul</firstname>
<lastname>McCartney</lastname>
</name>
<job>Singer</job>
<gender>Male</gender>
</person>
And this is the corresponding xsl (products.xsl)
<xsl:template match="child::person">
<html>
<head>
<title>
<xsl:value-of select="descendant::firstname" />
<xsl:text> </xsl:text>
<xsl:value-of select="descendant::lastname" />
</title>
</head>
<body>
<xsl:value-of select="descendant::firstname" />
<xsl:text> </xsl:text>
<xsl:value-of select="descendant::lastname" />
</body>
</html>
</xsl:template>
</xsl:stylesheet>
I just found out what the problem is: I put the XML/XSLT files in res/xml not in res/raw with the result of mangled XML format.
Much ado about nothing 🙁
