AW: It's possible to give external parameters in xslt?

hi,

XSL:
you need to put an xsl:param element in the xsl stylesheet:
	<xsl:param name="p1" select="'default value of not set from java'"/>

this can be used exactly like xsl:variable's:
	<xsl:value-of select="$p1"/>  -> default value of not set from java 

JAVA:
in your java code you just need to call
	transformer2.setParameter(paramname, paramvalue)
so e.g.
	transformer2.setParameter("p1", "hi there")

then the output would be
	<xsl:value-of select="$p1"/>  -> hi there 


i did not run the example, so there might be a typo but this is the way it works. just look into the javax.xml.transform javadoc to find the docs for setParameter.
