Come posso convertire una stringa in maiuscolo o minuscolo con XSLT?

Question

Come si fa la conversione del caso in XSL?

<xsl:variable name="upper">UPPER CASE</xsl:variable> 
<xsl:variable name="lower" select="???"/> 

Answer 1

in XSLT 1.0 le upper-case() e lower-case() funzioni non sono disponibili. Se stai usando un foglio di stile 1.0 del metodo comune di conversione caso è translate():

<xsl:variable name="smallcase" select="'abcdefghijklmnopqrstuvwxyz'" /> 
<xsl:variable name="uppercase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'" /> 


<xsl:template match="/"> 
    <xsl:value-of select="translate(doc, $smallcase, $uppercase)" /> 
</xsl:template> 

Answer 2

maiuscola (stringa) e minuscola (stringa)

Answer 3

XSLT 2.0 ha upper-case() e lower-case() funzioni. In caso di XSLT 1.0, è possibile utilizzare translate():

<xsl:value-of select="translate("xslt", "abcdefghijklmnopqrstuvwxyz", "ABCDEFGHIJKLMNOPQRSTUVWXYZ")" /> 

Answer 4

implementazione .NET XSLT permette di scrivere funzioni gestite personalizzato nel foglio di stile. Per la minuscola() può essere:

<?xml version="1.0" encoding="utf-8"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:utils="urn:myExtension" exclude-result-prefixes="msxsl"> 

    <xsl:output method="xml" indent="yes"/> 

    <msxsl:script implements-prefix="utils" language="C#"> 
    <![CDATA[ 
     public string ToLower(string stringValue) 
     { 
     string result = String.Empty; 

     if(!String.IsNullOrEmpty(stringValue)) 
     { 
      result = stringValue.ToLower(); 
     } 

     return result; 
     } 
    ]]> 
    </msxsl:script> 

    <!-- using of our custom function --> 
    <lowercaseValue> 
    <xsl:value-of select="utils:ToLower($myParam)"/> 
    </lowercaseValue> 

Assumere, che può essere lento, ma comunque accettabile.

Non dimenticare di abilitare gli script incorporati supporto per trasformare:

// Create the XsltSettings object with script enabled. 
XsltSettings xsltSettings = new XsltSettings(false, true); 

XslCompiledTransform xslt = new XslCompiledTransform(); 

// Load stylesheet 
xslt.Load(xsltPath, xsltSettings, new XmlUrlResolver()); 

Answer 5

<xsl:variable name="upper">UPPER CASE</xsl:variable> 
<xsl:variable name="lower" select="translate($upper,'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz')"/> 
<xsl:value-of select ="$lower"/> 

//displays UPPER CASE as upper case 

Answer 6

Per la codifica di caratteri ANSI:

translate(//variable, 'ABCDEFGHIJKLMNOPQRSTUVWXYZÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝÞŸŽŠŒ', 'abcdefghijklmnopqrstuvwxyzàáâãäåæçèéêëìíîïðñòóôõöøùúûüýþÿžšœ')
