编写一个 XSLT 样式表来制作 XML 文档的副本。源文档具有大写的元素和属性名称。输出文档应该是一个精确的副本,除了元素和属性名称是小写的。例如,它应该转换:
<p>
<BODY ATTRIBUTE="TheValue">
<H1>Hello world</H1>
</BODY>
into
<body attribute=”TheValue”>
<h1>Hello world</h1>
</body>
尝试这个:
<?xml version="1.0"?>
<!-- Transform a document to itself, lowercasing all tag names -->
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- Import the identity transformation -->
<!-- Whenever you match any node or any attribute -->
<xsl:template match="node()|@*">
<!-- Copy the current node -->
<xsl:copy>
<!-- Including any attributes it has and any child nodes -->
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<!-- Whenever you match any node or any attribute -->
<!-- When you match any element -->
<xsl:template match="*">
<!-- Create the same element with a lowercase name -->
<xsl:element name="{translate(name(),'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz')}">
<!-- Including any attributes it has and any child nodes -->
<xsl:apply-templates select="@*|node()"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
