使用xslt筛选特定节点值_Xslt_Filter_Transform

使用xslt筛选特定节点值

xslt filter

使用xslt筛选特定节点值,xslt,filter,transform,Xslt,Filter,Transform,我需要过滤大量冗余的xml文件。简单的方法是消除所有没有属性和内容的节点： <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:if test=". != '' or ./@* != ''"> <xsl:copy> <x

我需要过滤大量冗余的xml文件。简单的方法是消除所有没有属性和内容的节点：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="@*|node()">
    <xsl:if test=". != '' or ./@* != ''">
      <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
      </xsl:copy>
    </xsl:if>
  </xsl:template>
</xsl:stylesheet>

但我还需要过滤掉包含

<type>0</type>

仅包含

<whatever id="-1 />



请注意，count（@*[.=''）=count（@*）
可以写成而不是（@*[.！=''）
，如果你愿意的话。
为什么输出中保留了一些空节点（例如，
），而没有其他节点？@legostrmtroopr，因为我手工编辑了条目，忘了删除它；）这应该和其他人一起进行。我编辑了上面的内容，我希望我没有忘记任何事情。我应该删除：空标记（没有文本和属性）；空标记（无文本，某些属性的内容为空）；默认标记（带有属性id=“-1”
）的标记；特定标记（0
）；可能是一些其他特定的标签（例如：0.00
）好的，谢谢。它起作用了！这将在删除标记的位置留下一个空行；我怎么才能去掉空行呢？首先，尝试将
与
一起使用。前者指示XSL处理器缩进输出（doh！），后者删除空文本节点（即元素之间的空白）。输出格式取决于处理器和缩进效果。但实际上。。。不要花太多时间把它弄得漂亮。不重要的空白之所以有这个名称是有原因的。结果是我不能使用
，因为它会删除“有趣的”节点。我真正需要做的是杀死所有没有“filename”子节点的“image*”节点。我尝试了几件事，包括：*[以（名称（），“图像”）开始，而不是（文件名）]
，*[以（名称（），“图像”）开始，而不是（计数（文件名））]
，*[以（名称（），“图像”）开始，而不是（后代：：*[名称（）=”文件名“]）
，///image2[文本（）=0]
，以及更多的变体，但都没有用。请提供帮助。原则上，您的第一次尝试，match=“*[以（name（），'image'）开头，而不是（filename）]”应该可以做到这一点。其他人也没有错，只是没有那么简短。单独尝试这些条件，看看哪一个失败。
