【问题描述】:
假设我有以下 XML:
XML
<bookstore>
<book category="cooking">
<title lang="en">Everyday Italian</title>
<author>Giada De Laurentiis</author>
<year>2005</year>
<price>30.00</price>
</book>
<book category="children">
<title lang="en">Harry Potter</title>
<author>J K. Rowling</author>
<year>2005</year>
<price>29.99</price>
</book>
<book category="web">
<title lang="en">XQuery Kick Start</title>
<author>James McGovern</author>
<author>Per Bothner</author>
<author>Kurt Cagle</author>
<author>James Linn</author>
<author>Vaidyanathan Nagarajan</author>
<year>2003</year>
<price>49.99</price>
</book>
<book category="web" cover="paperback">
<title lang="en">Learning XML</title>
<author>Erik T. Ray</author>
<year>2003</year>
<price>39.95</price>
</book>
并遵循 XSLT:
XSLT
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:fn="http://www.w3.org/2005/xpath-functions"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
exclude-result-prefixes="fo xs fn msxsl">
<xsl:output method="xml" indent="yes" />
<xsl:template match="/">
<xsl:element name="rootnode">
<xsl:choose>
<xsl:when test="//bookstore/book[year!=2005]">
<xsl:message select="'book exists'" />
<xsl:apply-templates></xsl:apply-templates>
</xsl:when>
</xsl:choose>
</xsl:element>
</xsl:template>
<xsl:template match="book[year!=2005]">
<xsl:element name="not2005">
<xsl:copy-of select="." />
</xsl:element>
<!--<xsl:apply-templates select="@* | node()" />-->
</xsl:template>
</xsl:stylesheet>
转换后的 xml 如下所示:
结果
<?xml version="1.0" encoding="UTF-8"?>
<rootnode>Everyday ItalianGiada De Laurentiis200530.00Harry PotterJ K. Rowling200529.99<not2005>
<book category="web">
<title lang="en">XQuery Kick Start</title>
<author>James McGovern</author>
<author>Per Bothner</author>
<author>Kurt Cagle</author>
<author>James Linn</author>
<author>Vaidyanathan Nagarajan</author>
<year>2003</year>
<price>49.99</price>
</book>
</not2005>
<not2005>
<book category="web" cover="paperback">
<title lang="en">Learning XML</title>
<author>Erik T. Ray</author>
<year>2003</year>
<price>39.95</price>
</book>
</not2005>
</rootnode>
而不是我所期待的:
预期结果
<?xml version="1.0" encoding="UTF-8"?>
<rootnode>
<not2005>
<book category="web">
<title lang="en">XQuery Kick Start</title>
<author>James McGovern</author>
<author>Per Bothner</author>
<author>Kurt Cagle</author>
<author>James Linn</author>
<author>Vaidyanathan Nagarajan</author>
<year>2003</year>
<price>49.99</price>
</book>
</not2005>
<not2005>
<book category="web" cover="paperback">
<title lang="en">Learning XML</title>
<author>Erik T. Ray</author>
<year>2003</year>
<price>39.95</price>
</book>
</not2005>
</rootnode>
为什么跟随被转换/拾取?
日常意大利语Giada De Laurentiis200530.00哈利波特J K. 罗琳200529.99
还很好奇为什么我的 xsl:message 也没有弹出?
<xsl:message select="'book exists'" />
任何解释我显然缺少的基本概念的文章指针将不胜感激......

恭喜:与这里的一半人不同,您不只是想剪切和粘贴示例代码,您还想了解概念。我写我的书时考虑到像你这样的人:来自 Wiley 的 XSLT 2.0/XPath 2.0 程序员参考。

@MichaelKay 感谢迈克尔的这些客气话
