Retriving xsl atributes to a hashtable

[Former Member]

Hi to you all,

I´m trying to develop a program that will read a xsl file and return me all the atributes eg:

I want to read this xsl and write it on a hashtable.

Is it possible? Because I don´t know where to start.

Best Regards

HI

SAP web as supports xsl Transformation in follwing ways

1)using the standard sun JAXP API

2)Java language binded with XSL

Hi Natasha,

Try this:

try {
	SAXParserFactory factory = SAXParserFactory.newInstance();
	SAXParser parser = factory.newSAXParser();
	 
	StringReader sr = new StringReader(XSL.trim());
	InputSource is = new InputSource(sr);
	XSLDataHandler xslDataHandler = new XSLDataHandler();
	parser.parse(is, xslDataHandler);
	Hashtable attributes = xslDataHandler.getAttributes();
	
} catch (Exception e) {
}

private static final String XSL = 
		"<?xml version="1.0"?>"
		+ "<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">"
		+ "<xsl:for-each select="/Props">" 
		+ "<root>" 
		+ "<News>" 
		+ "<xsl:attribute name="Namesapace"><a href="http://com.sap/xmlns/cm" TARGET="test_blank">http://com.sap/xmlns/cm</a></xsl:attribute>" 
		+ "<xsl:attribute name="Prop">News</xsl:attribute>" 
		+ "<xsl:attribute name="Value">23</xsl:attribute>" 
		+ "</News>" 
		+ "</root>" 
		+ "</xsl:for-each>"
		+ "</xsl:stylesheet>";

	public class XSLDataHandler extends DefaultHandler {
		private Hashtable attributes = new Hashtable();
		private String lastAttribute;
		public void startElement(
			String namespaceURI,
			String localName,
			String rawName,
			Attributes atts) {
			if ("attribute".equals(localName)) {
				lastAttribute = atts.getValue("name");
			}
		}

		public void endElement(
			String namespaceURI,
			String localName,
			String rawName) {
			if ("attribute".equals(localName)) {
				lastAttribute = null;
			}
		}

		public void characters(char[] data, int off, int length) {
			if (null != lastAttribute) {
				final String value = new String(data, off, length).trim();
				if (!"".equals(value)) {
					attributes.put(lastAttribute, value);
				}
			}
		}

		private void setAttributes(Hashtable attributes) {
			this.attributes = attributes;
		}

		private Hashtable getAttributes() {
			return attributes;
		}
	}

Hi,

I´ve got already the XSL file, I don´t want to create a "private static final String XSL", I want to retrive from a filesystem and then retrive the atributes that it has.

It is confusing

Natasha,

use DOM to parse your xsl file and access the attributes via the DOM API.

Hi Natasha,

instead of

StringReader sr = new StringReader(XSL.trim());
InputSource is = new InputSource(sr);

put

InputStream istream = this.getClass().getClassLoader().getResourceAsStream("com/sap/sdn/attributes.xsl");
InputSource is = new InputSource( istream );
