Question

我有xml以下，我需要使用xslt

转换为以下xml

在输入xml中，我引用了最顶层节点，其子节点如下：

<?xml version="1.0"?>
<referenced>
  <name>PocTree/PocTree.services:getReferencesForServices</name>

预期输出XML结构应该类似于：

 <?xml version="1.0"?>
    <nodeInfo>
      <name>PocTree/PocTree.services:getReferencesForServices</name>
      <LOCK_STATUS>3</LOCK_STATUS>
      <type>flow</type>
      <path/>
      <isPub>false</isPub>
      <isNotification>false</isNotification>
      <isFlowServiceDisabled>false</isFlowServiceDisabled>
      <status>reference</status>
      <children>
        <name>WmRoot/wm.server.ns.dependency:getReferenced</name>
        <LOCK_STATUS>2</LOCK_STATUS>
        <type>java</type>
        <path>/Flow Path;1.0/INVOKE;0</path>
        <isPub>false</isPub>
        <isNotification>false</isNotification>
        <isFlowServiceDisabled>false</isFlowServiceDisabled>
        <status>resolved</status>
      </children>
      <children>
        <name>WmPublic/pub.xml:documentToXMLString</name>
        <LOCK_STATUS>2</LOCK_STATUS>
        <type>java</type>
        <path>/Flow Path;1.0/INVOKE;1</path>
        <isPub>false</isPub>
        <isNotification>false</isNotification>
        <isFlowServiceDisabled>false</isFlowServiceDisabled>
        <status>resolved</status>
      </reference>
      <children>
        <name>PocTree/PocTree.services:jkl</name>
        <LOCK_STATUS>3</LOCK_STATUS>
        <type>xsltservice</type>
        <path>/Flow Path;1.0/INVOKE;2</path>
        <isPub>false</isPub>
        <isNotification>false</isNotification>
        <isFlowServiceDisabled>false</isFlowServiceDisabled>
        <status>resolved</status>
      </children>
      <children>
        <name>WmPublic/pub.xml:xmlStringToXMLNode</name>
        <LOCK_STATUS>2</LOCK_STATUS>
        <type>java</type>
        <path>/Flow Path;1.0/INVOKE;3</path>
        <isPub>false</isPub>
        <isNotification>false</isNotification>
        <isFlowServiceDisabled>false</isFlowServiceDisabled>
        <status>resolved</status>
      </children>
      <children>
        <name>WmPublic/pub.xml:xmlNodeToDocument</name>
        <LOCK_STATUS>2</LOCK_STATUS>
        <type>java</type>
        <path>/Flow Path;1.0/INVOKE;4</path>
        <isPub>false</isPub>
        <isNotification>false</isNotification>
        <isFlowServiceDisabled>false</isFlowServiceDisabled>
        <status>resolved</status>
      </children>
      <children>
        <name>PocTree/PocTree.services:ghi</name>
        <LOCK_STATUS>4</LOCK_STATUS>
        <type>xsltservice</type>
        <path>/Flow Path;1.0/INVOKE;5</path>
        <isPub>false</isPub>
        <isNotification>false</isNotification>
        <isFlowServiceDisabled>false</isFlowServiceDisabled>
        <status>resolved</status>
      </children>
    </nodeInfo>

但是获得预期输出xml的标准是来自输入xml的一个子节点的值，即本节

  <type>
        <svc_type>flow</svc_type>
        <svc_subtype>default</svc_subtype>
      </type>

哪个时候有一个额外的标签，这个意思可以有子节点或只有。

 <type>
    <type_name>record</type_name>
  </type>

现在应该设计预期的输出XML，只选择输入xml中的那些<refrence>标签，其中<svc_type>具有'flow'或'javaservice'或'xsltservice'的值，并省略{ {1}} <refrence>属于<type_name>父节点且具有任何值的标记。

此外，<type>的内容应该映射到<svc_type>的值，输出xml不应包含其父节点<type>的子节点<svc_type>和<svc_subtype>

请帮助解决这个问题。

包括为实现输入XML的过滤而编写的xslt

<type>

但是上面的xslt仍未涵盖此部分 - <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" indent="yes" encoding="utf-8"/> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="referenced"> <nodeInfo> <xsl:apply-templates /> </nodeInfo> </xsl:template> <xsl:template match="(reference[type/svc_type[contains(., 'flow') or contains(., 'java') or contains(., 'xsltservice')]]) and (reference[type/type_name[not(contains(.,'record'))]])"> <children> <xsl:apply-templates /> </children> </xsl:template> </xsl:stylesheet>应映射到<svc_type>的值，输出xml不应包含其父节点<type>的子节点<svc_type>和<svc_subtype>。

Answer 1

你需要改变你的逻辑。您不必考虑要复制的节点，而是要考虑您不想复制的内容，并编写模板以匹配这些节点，并忽略它们。

然后，身份模板将处理您要复制的所有内容。

因此，您说要包含输入xml中的<reference>个标记，其中<svc_type>的值为＆＃39; flow＆＃39;或者＆＃39; javaservice＆＃39;或者＆＃39; xsltservice＆＃39;。与此相反的是，您希望排除不会将<reference>设置为这三个值中的任何一个的<svc_type>：

<xsl:template match="reference[type/svc_type[not(contains(., 'flow') or contains(., 'java') or contains(., 'xsltservice'))]]" />

你的其他规则已经是一个关于删除的规则，因此可以直接进行而无需任何逻辑反转

<xsl:template match="reference[type/type_name]" priority="2" />

此处可能不需要优先级，除非您的reference标记同时具有type/type_name和type/svc_type，在这种情况下，模板之间会发生冲突< / p>

试试这个XSLT

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" encoding="utf-8"/>

    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="referenced">
        <nodeInfo>
            <xsl:apply-templates />
        </nodeInfo>
    </xsl:template>

    <xsl:template match="reference">
        <children>
            <xsl:apply-templates />
        </children>
    </xsl:template>

    <xsl:template match="type[svc_type]">
        <type>
            <xsl:value-of select="svc_type" />
        </type>
    </xsl:template>

    <xsl:template match="reference[type/svc_type[not(contains(., 'flow') or contains(., 'java') or contains(., 'xsltservice'))]]" />

    <xsl:template match="reference[type/type_name]" priority="2" />
</xsl:stylesheet>

另请注意添加模板以便将svc_type上的转换处理为type。

具有多个匹配条件的标识模板的XSLT和删除未使用的节点
