How do you do case conversion in XSL?

你如何在 XSL 中进行大小写转换?

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

回答by Jon W

In XSLT 1.0 the upper-case()and lower-case()functions are not available. If you're using a 1.0 stylesheet the common method of case conversion is translate():

在 XSLT 1.0 中,upper-case()lower-case()函数不可用。如果您使用的是 1.0 样式表,则大小写转换的常用方法是translate()

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


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

XSLT 2.0 has upper-case()and lower-case()functions. In case of XSLT 1.0, you can use translate():

XSLT 2.0 具有upper-case()lower-case()功能。在 XSLT 1.0 的情况下,您可以使用translate()

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

.NET XSLT implementation allows to write custom managed functions in the stylesheet. For lower-case() it can be:

.NET XSLT 实现允许在样式表中编写自定义托管函数。对于小写(),它可以是:

<?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>

Assume, that can be slow, but still acceptable.

假设,这可能很慢,但仍然可以接受。

Do not forget to enable embedded scripts support for transform:

不要忘记为转换启用嵌入式脚本支持:

// 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());

<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

For ANSI character encoding:

对于 ANSI 字符编码:

 translate(//variable, 'ABCDEFGHIJKLMNOPQRSTUVWXYZàá??????èéê?ìí??D?òó????ùú?üYT????', 'abcdefghijklmnopqrstuvwxyzàáa?????èéê?ìí??e?òó????ùú?üyt????')

upper-case(string) and lower-case(string)

大写(字符串)和小写(字符串)
