[英]Parse string to XML and xPath into it - XSLT 2 or 3
Answers can be XSLT 2.0 or 3.0; 答案可以是XSLT 2.0或3.0; Saxon EE parser
Saxon EE解析器
Given XML sample: 给定的XML示例:
<theRootNode xmlns="http://myNamespace">
<xml>
<Company>
<TaxIdentity>
<id/>
</TaxIdentity>
<TaxIdentity>
<id>42-123456</id>
</TaxIdentity>
<Name>ABC Company</Name>
<Number>2230</Number>
</Company>
</xml>
</theRootNode>
I have a 2.0 XSLT stylesheet which removes the namespaces and parses the xml node. 我有一个2.0 XSLT样式表,它删除了名称空间并解析了xml节点。 Within the same transform I now need to remove any 'TaxIdentity' nodes which have empty values within the xml node I just parsed.
在同一个转换中,我现在需要删除所有“ TaxIdentity”节点,这些节点在我刚解析的xml节点中具有空值。
Current results are: 当前结果是:
<theRootNode>
<xml>
<Company>
<TaxIdentity>
<id/>
</TaxIdentity>
<TaxIdentity>
<id>42-123456</id>
</TaxIdentity>
<Name>ABC Company</Name>
<Number>2230</Number>
</Company>
</xml>
</theRootNode>
Desired results are: 所需的结果是:
<theRootNode>
<xml>
<Company>
<TaxIdentity>
<id>42-123456</id>
</TaxIdentity>
<Name>ABC Company</Name>
<Number>2230</Number>
</Company>
</xml>
</theRootNode>
My XSLT is below. 我的XSLT在下面。 Note that my thought was to put the initial results into a variable using as="element() or use parse-xml (version 3) but I can't seem remove the empty nodes. Note that my goal is NOT to remove all empty elements or nodes...just ones named TaxIdentiy. What approach should I take? Solutions? I really need it all within the same transform. Thanks.
请注意,我的想法是使用as =“ element()或使用parse-xml(版本3)将初始结果放入变量中,但我似乎无法删除空节点。请注意,我的目标不是删除所有空节点。元素或节点...只是命名为TaxIdentiy的元素或节点,我应该采用哪种方法?解决方案?我真的需要在同一转换中全部使用它们。
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="no" omit-xml-declaration="yes"/>
<!-- Copy elements without copying their namespace declarations -->
<xsl:template match="*[not(local-name() = 'xml')]" name="identity">
<xsl:element name="{name()}" namespace="">
<xsl:apply-templates select="node() | @*"/>
</xsl:element>
</xsl:template>
<!-- Copy content as is with lower priority -->
<xsl:template match="node() | @*" priority="-2">
<xsl:copy>
<xsl:apply-templates select="node() | @*"/>
</xsl:copy>
</xsl:template>
<!-- turn xml node content back into xml -->
<xsl:template match="*[local-name() = 'xml']">
<xsl:element name="xml" inherit-namespaces="no" namespace="">
<xsl:value-of select="." disable-output-escaping='yes'/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Here is my XSLT 3.0 suggestion which simply parses the XML with parse-xml
and then apply-templates to the parsed nodes with a template removing the TaxIdentity
with all empty child elements: 这是我的XSLT 3.0建议,该建议仅使用
parse-xml
,然后使用删除所有空子元素的TaxIdentity
模板将模板应用于已解析的节点:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:math="http://www.w3.org/2005/xpath-functions/math"
xmlns:is="http://myNamespace"
exclude-result-prefixes="is xs math"
version="3.0">
<xsl:mode on-no-match="shallow-copy"/>
<xsl:template match="is:*">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="@* , node()"></xsl:apply-templates>
</xsl:element>
</xsl:template>
<xsl:template match="is:xml">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="parse-xml(.)/node()"/>
</xsl:element>
</xsl:template>
<xsl:template match="TaxIdentity[not(*[normalize-space()])]"/>
</xsl:stylesheet>
