[英]xslt 1.0- Using xslt 1.0 how can I make the xslt work for multiple document elements
这是我的XML-
<?xml version="1.0" encoding="UTF-8"?>
<update-all-attributes>
<document name="http://blah">
<price>111 USD</price>
<color>red</color>
<size>comfort</size>
<cost>00012-40</cost>
<shipping>US::Ground:0.00</shipping>
<cost>00012-40</cost>
<price>111 USD</price>
<color>red</color>
<size>comfort</size>
<cost>00012-40</cost>
<shipping>US::Ground:0.00</shipping>
<cost>00012-40</cost>
<price>111 USD</price>
<color>red</color>
<size>comfort</size>
<shipping>US::Ground:0.00</shipping>
<price>111 USD</price>
<color>red</color>
<size>comfort</size>
</document>
<document name="http://blahblah">
<price>110 USD</price>
<color>blue</color>
<size>super</size>
<cost>00012-41</cost>
<shipping>US::Ground:0.01</shipping>
<cost>00012-41</cost>
<price>110 USD</price>
<color>blue</color>
<size>super</size>
<shipping>US::Ground:0.01</shipping>
<cost>00012-41</cost>
<price>110 USD</price>
<color>blue</color>
<size>super</size>
<shipping>US::Ground:0.01</shipping>
<price>110 USD</price>
<color>blue</color>
<size>super</size>
</document>
</update-all-attributes>
我希望我的最终XML为
<?xml version="1.0" encoding="UTF-8"?>
<document name="http://blah">
<price>111 USD</price>
<color>red</color>
<size>comfort</size>
<cost>00012-40,00012-40,00012-40,00012-40</cost>
<shipping>US::Ground:0.00,US::Ground:0.00,US::Ground:0.00</shipping>
</document>
<document name="http://blahblah">
<price>110 USD</price>
<color>blue</color>
<size>super</size>
<cost>00012-41,00012-41,00012-41,00012-41</cost>
<shipping>US::Ground:0.01,US::Ground:0.01,US::Ground:0.01</shipping>
</document>
这是使用的XSLT(感谢Thomas W)-
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:key name="element-by-name" match="document/*" use="local-name()"/>
<!-- Copy everything, unless other templates say otherwise -->
<xsl:template match="*|@*">
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<!-- Skip elements if there are elements of the same name earlier in the document.
Priority is set to 1 so that this template overrides other templates
and we don't accidentally still get duplicates. -->
<xsl:template match="*[count(. | key('element-by-name', local-name())[1]) > 1]" priority="1"/>
<!-- This template is for elements we want to be multi-value -->
<xsl:template match="shipping | cost">
<xsl:copy>
<!-- We step through all elements of the same name -->
<xsl:for-each select="key('element-by-name', local-name())">
<xsl:value-of select="."/>
<xsl:if test="position() != last()">,</xsl:if>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
这仅对一个文档元素有效,我有多个文档元素,那么如何对所有文档元素起作用?
您可以通过更改键来做到这一点,以使其同时使用元素名称和其document
父级的唯一ID作为查找值。
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:key name="element-by-name-and-parent" match="document/*"
use="concat(local-name(), generate-id(..))"/>
<!-- Copy everything, unless other templates say otherwise -->
<xsl:template match="*|@*">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<!-- Skip siblings of the same name within the same parent element; only use first occurrence -->
<xsl:template match="*[count(. | key('element-by-name-and-parent',
concat(local-name(), generate-id(..)))[1]) > 1]"
priority="1"/>
<!-- This template is for elements we want to be multi-value -->
<xsl:template match="shipping | cost">
<xsl:copy>
<!-- Step through all elements of the same name that belong to the same parent -->
<xsl:for-each select="key('element-by-name-and-parent',
concat(local-name(), generate-id(..)))">
<xsl:value-of select="."/>
<xsl:if test="position() != last()">,</xsl:if>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
输出(根元素与输入XML中的根元素相同;您在问题中要求的输出没有根元素):
<?xml version="1.0" encoding="UTF-8"?>
<update-all-attributes>
<document name="http://blah">
<price>111 USD</price>
<color>red</color>
<size>comfort</size>
<cost>00012-40,00012-40,00012-40,00012-40</cost>
<shipping>US::Ground:0.00,US::Ground:0.00,US::Ground:0.00</shipping>
</document>
<document name="http://blahblah">
<price>110 USD</price>
<color>blue</color>
<size>super</size>
<cost>00012-41,00012-41,00012-41</cost>
<shipping>US::Ground:0.01,US::Ground:0.01,US::Ground:0.01</shipping>
</document>
</update-all-attributes>
