我需要将现有的XML结构转换为另一种XML结构。
XMLSource:
<?xml version="1.0"?>
<content>
<first>Paragraph-1</first>
<comment>Comment-1</comment>
<likes>like-1</likes>
<first>Paragraph-2</first>
<comment>Comment-2</comment>
<likes>like-2</likes>
<first>Paragraph-3</first>
<comment>Comment-3</comment>
</content>
需要的输出格式:
<content1>
<block>
<aaa>Paragraph-1</aaa>
<bbb>Comment-1</bbb>
<ccc>like-1</ccc>
</block>
<block>
<aaa>Paragraph-2</aaa>
<bbb>Comment-2</bbb>
<ccc>like-2</ccc>
</block>
<block>
<aaa>Paragraph-3</aaa>
<bbb>Comment-3</bbb>
</block>
</content1>
如何使用XSLT完成此操作。 请帮忙。

请在下方观看强大的XML,如果您需要更多建议,请与我们联系。 :)我提供的不仅仅是你提出的问题。
INPUT XML:
<?xml version="1.0" encoding="utf-8"?>
<content>
<first>Paragraph-1</first>
<likes>like-1</likes>
<first>Paragraph-2</first>
<comment>Comment-2</comment>
<likes>like-2</likes>
<first>Paragraph-3</first>
<comment>Comment-3</comment>
<first>Paragraph-4</first>
<comment>Comment-4</comment>
<likes>like-4</likes>
</content>
XSLT代码:
<?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" exclude-result-prefixes="msxsl"
>
<xsl:output method="xml" indent="yes"/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="content">
<xsl:element name="content1">
<xsl:apply-templates select="node()|@*"/>
</xsl:element>
</xsl:template>
<xsl:template match="first">
<xsl:variable name="count" select="count(following-sibling::first)"/>
<xsl:element name="block">
<aaa>
<xsl:apply-templates select="node()|@*"/>
</aaa>
<xsl:for-each select="following-sibling::comment[1][count(following-sibling::first) = $count]">
<bbb>
<xsl:apply-templates select="node()|@*"/>
</bbb>
</xsl:for-each>
<xsl:for-each select="following-sibling::likes[1][count(following-sibling::first) = $count]">
<ccc>
<xsl:apply-templates select="node()|@*"/>
</ccc>
</xsl:for-each>
</xsl:element>
</xsl:template>
<xsl:template match="comment|likes"/>
</xsl:stylesheet>
输出XML:
<?xml version="1.0" encoding="utf-8"?>
<content1>
<block>
<aaa>Paragraph-1</aaa>
<ccc>like-1</ccc>
</block>
<block>
<aaa>Paragraph-2</aaa>
<bbb>Comment-2</bbb>
<ccc>like-2</ccc>
</block>
<block>
<aaa>Paragraph-3</aaa>
<bbb>Comment-3</bbb>
</block>
<block>
<aaa>Paragraph-4</aaa>
<bbb>Comment-4</bbb>
<ccc>like-4</ccc>
</block>
</content1>
这就像宝石一样!!!!!! :d

这是一个XSLT 2.0示例:
<xsl:stylesheet
version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:param name="start-name" select="'a'"/>
<xsl:param name="nchars" select="3"/>
<xsl:variable name="start-index" select="string-to-codepoints($start-name)"/>
<xsl:template match="content">
<content1>
<xsl:for-each-group select="*" group-starting-with="first">
<block>
<xsl:apply-templates select="current-group()"/>
</block>
</xsl:for-each-group>
</content1>
</xsl:template>
<xsl:template match="content/*">
<xsl:variable name="pos" select="position()"/>
<xsl:element name="{string-join(for $c in 1 to $nchars return codepoints-to-string($pos - 1 + $start-index), '')}">
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
答案 2 :(得分:0)
这是我喜欢的另一个XSLT 1.0选项,因为一切都有它自己的模板。我认为这比使用多个xsl:for-each
更容易增加样式表的复杂性。
XML输入
<content>
<first>Paragraph-1</first>
<likes>like-1</likes>
<first>Paragraph-2</first>
<comment>Comment-2</comment>
<likes>like-2</likes>
<first>Paragraph-3</first>
<comment>Comment-3</comment>
<first>Paragraph-4</first>
<comment>Comment-4</comment>
<likes>like-4</likes>
</content>
XSLT 1.0
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="content">
<content1>
<xsl:apply-templates select="node()|@*"/>
</content1>
</xsl:template>
<xsl:template match="first">
<block>
<aaa>
<xsl:apply-templates select="node()|@*"/>
</aaa>
<xsl:apply-templates select="following-sibling::*[1][name()='comment']" mode="mod"/>
<xsl:apply-templates select="following-sibling::*[1][name()='likes']" mode="mod"/>
</block>
</xsl:template>
<xsl:template match="comment" mode="mod">
<bbb>
<xsl:apply-templates select="node()|@*"/>
</bbb>
<xsl:apply-templates select="following-sibling::*[1][name()='likes']" mode="mod"/>
</xsl:template>
<xsl:template match="likes" mode="mod">
<ccc>
<xsl:apply-templates select="node()|@*"/>
</ccc>
</xsl:template>
<xsl:template match="comment|likes"/>
</xsl:stylesheet>
XML输出
<content1>
<block>
<aaa>Paragraph-1</aaa>
<ccc>like-1</ccc>
</block>
<block>
<aaa>Paragraph-2</aaa>
<bbb>Comment-2</bbb>
<ccc>like-2</ccc>
</block>
<block>
<aaa>Paragraph-3</aaa>
<bbb>Comment-3</bbb>
</block>
<block>
<aaa>Paragraph-4</aaa>
