Hi Andreas, The easiest way to deal with this is with recursion: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text"/> <xsl:template match="logging"> <xsl:if test="child::target[1]"> <xsl:call-template name="output-targets"> <xsl:with-param name="nodes" select="child::target"/> </xsl:call-template> </xsl:if> </xsl:template> <xsl:template name="output-targets"> <xsl:param name="nodes"/> <xsl:param name="pos" select="1"/> <xsl:param name="value" select="1"/> <xsl:choose> <xsl:when test="$nodes[$pos]"> <xsl:text>public static final int </xsl:text> <xsl:value-of select="translate($nodes[$pos]/@name, 'abcdefghijklmnopqrstuvwxyz', 'ABCDEFGHIJKLMNOPQRSTUVWXYZ')"/> <xsl:text> = </xsl:text> <xsl:value-of select="$value"/> <xsl:text>;
</xsl:text> <xsl:call-template name="output-targets"> <xsl:with-param name="nodes" select="$nodes"/> <xsl:with-param name="pos" select="$pos + 1"/> <xsl:with-param name="value" select="$value * 2"/> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:text>public static final int ALL = </xsl:text> <xsl:value-of select="$value"/> <xsl:text>;
</xsl:text> </xsl:otherwise> </xsl:choose> </xsl:template> </xsl:stylesheet> -----Original Message----- From: Andreas Mecky [mailto:andreasmecky@xxxxxxxx] Sent: 22 January 2003 09:06 To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: [xsl] calculating pow of numbers and a final sum Hello everybody, I am kind of a newbie to this mailing list and I have a problem that keeps me busy for some time now. I am working on a code generator for some java classes. This is my XML: <?xml version="1.0" ?> <logging> <target name="init"/> <target name="debug"/> <target name="fatal"/> </logging> this should result in: public static final int INIT = 1; public static final int DEBUG = 2; public static final int FATAL = 4; public static final int ALL = 8; I can get everything working except the numbers. How can I calculate the numbers which are something like counter=2^(pos-1)? This all entry is generated automatically. At this point I need either to sum all former values or do the same calculation as mentioned above. Some research on google did not helped me out. Any suggestions? Thanx in advance Andreas __________________________________________________________________ Gesendet von Yahoo!
