xml - 使用 XSLT 将 XML 文件转换为另一个 XML 文件，但部分代码不起作用

标签 xml xslt

这是我的 XML 文件(Input.xml):

我的输出(Output.xml)如下所示:

<?xml version="1.0" encoding="UTF-8"?>

         <S/>
         <MT N="X-Parsed-By" V=""/>
      </R>
   </RES>
</GSP>

您将在我的输出中看到标签 MT，并且其属性“V”没有任何值:

<MT N="X-Parsed-By" V=""/>

我的 XSLT 的以下部分无法正常工作。属性名称“V”未提取我的 XML 元素“X-Parsed-By”的值。程序的其他部分运行良好。

<MT>
<xsl:attribute name="N">X-Parsed-By</xsl:attribute>
<xsl:attribute name="V"><xsl:value-of select="extension/X-Parsed-By"/></xsl:attribute>
</MT>

我希望我的输出(Output.xml)看起来像这样..

.....
<MT N="X-Parsed-By" V="org.apache.tika.parser.EmptyParser"/>
...

如有任何帮助，我们将不胜感激

最佳答案

更改:

<xsl:attribute name="V"><xsl:value-of select="extension/X-Parsed-By"/></xsl:attribute>

至:

<xsl:attribute name="V"><xsl:value-of select="_source/extension/X-Parsed-By"/></xsl:attribute>

请注意，由于您使用的是 XSLT 2.0，因此可以将其缩短为:

<xsl:attribute name="V" select="_source/extension/X-Parsed-By"/>

更好的是，使用 attribute value template并将整个事情缩短为:

<MT N="X-Parsed-By" V="{_source/extension/X-Parsed-By}"/>
