Question

我试图将我的XML转换为XSL。

我成功完成了第一部分，但现在我仍然坚持第二部分。我尝试从其他地方定义的键中获取值。

也许更容易展示你：

传入XML文件：

正如您所看到的那样，那些有争议的人会查找“Frag＆＃39; Frag＆＃39;数据。在我的示例中：http://xsltransform.net/94hvTzt＆＃39; Frag＆＃39;你现在看到的数据，不应该属于那里......

有人能指出我正确的方向吗？

谢谢！

首先，不要这样做以在XSLT中创建元素......

 <xsl:text disable-output-escaping="yes">&lt;</xsl:text><xsl:value-of select="@name" /><xsl:text disable-output-escaping="yes">&gt;</xsl:text>

那种方式就是疯狂。如果要创建动态命名元素，请使用xsl:element命令。你只需要这样做....

 <xsl:element name="{@name}">
      <xsl:value-of select="."/>
 </xsl:element>

但是在回答您的问题时，要从XML文档中的其他位置查找日期，请使用xsl:key

 <xsl:key name="fragment" match="MAObject" use="GUID" />

要使用此密钥，要查找数据，您只需执行以下操作（假设您位于segment元素上）

 <xsl:value-of select="key('fragment', @contentid)/Meta" />

试试这个XSLT：

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

<xsl:key name="fragment" match="MAObject" use="GUID" />

<xsl:template match="/">
    <MediaHAVEN_external_metadata version="1.0" name="VIAA">
        <MDProperties>
            <MEDIA_ID><xsl:value-of select="AXFRoot/MAObject[StratumEx]/GUID" /></MEDIA_ID>
            <xsl:for-each select="AXFRoot/MAObject[StratumEx]/Meta">
                <xsl:element name="{@name}">
                    <xsl:value-of select="."/>
                </xsl:element>
            </xsl:for-each>
        </MDProperties>
        <fragments>
            <xsl:for-each select="AXFRoot/MAObject/StratumEx/Group/Segment">
                <fragment>
                    <title><xsl:value-of select="key('fragment', @contentid)/Meta" /></title>
                    <original_start_z><xsl:value-of select="@begin" /></original_start_z>
                    <original_end_z><xsl:value-of select="@end" /></original_end_z>
                </fragment>
            </xsl:for-each>
         </fragments>
    </MediaHAVEN_external_metadata>
</xsl:template>
</xsl:stylesheet>

或者也许这样，采取更基于模板的方法

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

<xsl:key name="fragment" match="MAObject" use="GUID" />

<xsl:template match="/">
    <MediaHAVEN_external_metadata version="1.0" name="VIAA">
        <xsl:apply-templates select="AXFRoot/MAObject[StratumEx]" />
    </MediaHAVEN_external_metadata>
</xsl:template>

<xsl:template match="MAObject">
    <MDProperties>
        <MEDIA_ID><xsl:value-of select="GUID" /></MEDIA_ID>
        <xsl:apply-templates select="Meta" />
    </MDProperties>
    <fragments>
        <xsl:apply-templates select="StratumEx/Group/Segment" />
     </fragments>
</xsl:template>

<xsl:template match="Meta">
    <xsl:element name="{@name}">
        <xsl:value-of select="."/>
    </xsl:element>
</xsl:template>

<xsl:template match="Segment">
    <fragment>
        <title><xsl:value-of select="key('fragment', @contentid)/Meta" /></title>
        <original_start_z><xsl:value-of select="@begin" /></original_start_z>
        <original_end_z><xsl:value-of select="@end" /></original_end_z>
    </fragment>
</xsl:template>
</xsl:stylesheet>

使用另一个位置上的值将XML转换为XSL
