XPath notes that the translate function is not a sufficient solution for case conversion in all languages. A future version of XPath may provide additional functions for case conversion.
However, this is the closest we have at present to a function that can convert a string to uppercase or lowercase.
<xsl:value-of select="translate('The quick brown fox.', 'abcdefghijklmnopqrstuvwxyz', 'ABCDEFGHIJKLMNOPQRSTUVWXYZ')" />
THE QUICK BROWN FOX.
abcis longer than
XYZ, then every occurrence of characters in
abcthat do not have a corresponding character in
XYZwill be removed.
<xsl:value-of select="translate('The quick brown fox.', 'brown', 'red')" />
The quick red fox.
XYZcontains more characters than
abc, the extra characters are ignored.
