Capitalize Element Name in XSL - xslt

Question

I am writing a XSL transformation and my source has an element like this - "title". The target xml should contain "Title". Is there a way to capitalize the first letter of a string in XSL?

Answer 1

Following on from the Johannes said, to create a new element using xsl:element you would probably do something like this
<xsl:template match="*">
<xsl:element name="{concat(upper-case(substring(name(), 1, 1)), substring(name(), 2))}">
<xsl:value-of select="." />
</xsl:element>
</xsl:template>
If your are using XSLT1.0, you won't be able to use the upper-case function. Instead, you will have to make-do with the cumbersome translate function
<xsl:element name="{concat(translate(substring(name(), 1, 1), 'abcdefghijklmnopqrstuvwxyz', 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'), substring(name(), 2))}">

Answer 2

Cleaner: use an existing library: FunctX XSLT http://www.xsltfunctions.com/ There's a function capitalize-first() http://www.xsltfunctions.com/xsl/functx_capitalize-first.html
No need to reinvent the wheel in every XSLT, stick the lib somewhere and xsl:include it.

Answer 3

I guess you have to manually use <xsl:element> and then something like the following beast:
concat(upper-case(substring(name(), 1, 1)), substring(name(), 2))

Here is a pure XLST1 template that creates CamelCase names from ASCII sentences.
<xsl:template name="Capitalize">
<xsl:param name="word" select="''"/>
<xsl:value-of select="concat(
translate(substring($word, 1, 1),
'abcdefghijklmnopqrstuvwxyz',
'ABCDEFGHIJKLMNOPQRSTUVWXYZ'),
translate(substring($word, 2),
'ABCDEFGHIJKLMNOPQRSTUVWXYZ',
'abcdefghijklmnopqrstuvwxyz'))"/>
</xsl:template>
<xsl:template name="CamelCase-recursion">
<xsl:param name="sentence" select="''"/>
<xsl:if test="$sentence != ''">
<xsl:call-template name="Capitalize">
<xsl:with-param name="word" select="substring-before(concat($sentence, ' '), ' ')"/>
</xsl:call-template>
<xsl:call-template name="CamelCase-recursion">
<xsl:with-param name="sentence" select="substring-after($sentence, ' ')"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
<xsl:template name="CamelCase">
<xsl:param name="sentence" select="''"/>
<xsl:call-template name="CamelCase-recursion">
<xsl:with-param name="sentence" select="normalize-space(translate($sentence, ":;,'()_", ' '))"/>
</xsl:call-template>
</xsl:template>
