I need to generate to the following:

Any hints???

Hi Mikael,

Try the translate() function, e.g.

<xsl:value-of
select="translate(@name,'abcdefghijklmnopqrstuvwxyz','ABCDEFGHIJKLMNOPQRSTUV
WXYZ')"/>

Hope this helps

Ooops, didn't read the question properly...

Try something like...

== XML =========================================
<?xml version="1.0"?>
<root>
<attribute name="bbBusState"/>
</root>
== end of XML ==================================

== XSL =========================================
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xslutput method="text"/>
<xsl:variable name="lcase" select="'abcdefghijklmnopqrstuvwxyz'"/>
<xsl:variable name="ucase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>

<xsl:template match="root">
<xsl:apply-templates select="attribute"/>
</xsl:template>

<xsl:template match="attribute">
<xsl:text>public static final String </xsl:text>
<xsl:call-template name="Camel2Underscore">
<xsl:with-param name="str" select="@name"/>
</xsl:call-template>
<xsl:text>_ATTR_TYPE</xsl:text>
</xsl:template>

<xsl:template name="Camel2Underscore">
<xslaram name="str"/>
<xslaram name="u-str"
select="translate($str,$ucase,'||||||||||||||||||||||||||')"/>
<xsl:choose>
<xsl:when test="substring($u-str,1,1) = '|'">
<xsl:text>_</xsl:text>
<xsl:value-of select="substring($str,1,1)"/>
<xsl:call-template name="Camel2Underscore">
<xsl:with-param name="str" select="substring($str,2)"/>
<xsl:with-param name="u-str" select="substring($u-str,2)"/>
</xsl:call-template>
</xsl:when>
<xsl:when test="contains($u-str,'|')">
<xsl:variable name="runlen"
select="string-length(substring-before($u-str,'|'))"/>
<xsl:value-of
select="translate(substring($str,1,$runlen),$lcase,$ucase)"/>
<xsl:call-template name="Camel2Underscore">
<xsl:with-param name="str" select="substring($str,$runlen + 1)"/>
<xsl:with-param name="u-str" select="substring($u-str,$runlen +
1)"/>
</xsl:call-template>
</xsl:when>
<xsltherwise>
<xsl:value-of select="translate($str,$lcase,$ucase)"/>
</xsltherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
== end of XSL ==================================

Hope this helps

Hi Mikael,

One can simply use the "str-map" template of FXSL as follows:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:testmap="my:testmap"
exclude-result-prefixes="xsl testmap"<xsl:import href="str-map.xsl"/>

<xsl:variable name="vLower" select="'abcdefghijklmnopqrstuvwxyz'"/>
<xsl:variable name="vUpper" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>

<xslutput omit-xml-declaration="yes" indent="yes"/>

<xsl:template match="/">
<xsl:variable name="vTestMap" select="document('')/*/testmap:*[1]"/>
<xsl:variable name="vName">
<xsl:call-template name="str-map">
<xsl:with-param name="pFun" select="$vTestMap"/>
<xsl:with-param name="pStr" select="*/@name"/>
</xsl:call-template>
</xsl:variable>

public static final String <xsl:text/>
<xsl:value-of select="$vName"/>
</xsl:template>

<testmap:testmap/>
<xsl:template match="testmap:*">
<xslaram name="arg1"/>

<xsl:if test="contains($vUpper, $arg1)">_</xsl:if>

<xsl:value-of select="translate($arg1, $vLower, $vUpper)"/>
</xsl:template>

</xsl:stylesheet>

When this transformation is applied on your source.xml:

<attribute name="bbBusState"/>

the wanted output is produced:

public static final String BB_BUS_STATE



Hope this helped.
