How to remove xmlns tag in Node level

Question

Hi Experts!
How to remove xmlns tag in xml file, where only xmlns="". I do not want to remove if xmlns contains a value.
I am using below xslt mapping, but it is removing all xmlns tags in a xml file. I want to remove only xmlns="" .
please help me on this.
Here is the code:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://www.arconw.com/XI/XSLT_Library/XmlNamespacePrefixRemoval"
version="1.0">
<xsl:output method = "xml" />
<xsl:template match="/">
<xsl:apply-templates select="*" mode="remprefix"/>
</xsl:template>
<xsl:template match="*" mode="remprefix">
<xsl:variable name="newname" select="local-name(.)"/>
<xsl:element name="{$newname}" namespace ="{namespace-uri()}">
<xsl:apply-templates mode="copyall" select="@*|comment()|processing-instruction()|text()"/>
<xsl:apply-templates select="*" mode="remprefix"/>
</xsl:element>
</xsl:template>
<xsl:template mode="copyall" match="@*|comment()|processing-instruction()|text()">
<xsl:copy>
<xsl:apply-templates mode="copyall" select="@*|comment()|processing-instruction()|text()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

Hi Hari,
Please try this as an option:
import java.io.InputStream;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.io.StringWriter;
import java.util.Map;
import com.sap.aii.mapping.api.StreamTransformation;
import com.sap.aii.mapping.api.StreamTransformationException;
public class RemoveBlankNS implements StreamTransformation {
     private Map _param;    
     public void setParameter(Map param) {
          _param = param;
     public void execute(InputStream in, OutputStream out) throws StreamTransformationException {
          try {
               byte[] bytes = new byte[in.available()];
               in.read(bytes, 0, in.available());
               String payload = new String(bytes, "UTF-8");               
               payload = payload.replaceAll(" xmlns=\"\"", "");
               out.write(payload.getBytes("UTF-8"));
          } catch (Exception e) {
               StringWriter sw = new StringWriter();
               PrintWriter pw = new PrintWriter(sw);
               e.printStackTrace(pw);
               throw new StreamTransformationException(sw.toString());
Thanks,
