通过XSLT从XML中删除特定的空标记

Question

我有以下过程的XML

<p>In technical jargon<sup></sup>, the expect<span class="insert"></span><span class="insert"></span><span class="insert">ed</span> excess return on a factor is proportional to the negative of the factor covariance with the pricing kernel, <br/>given by marginal utility of consumption for a representative agent.</p>

我使用下面的xsl来删除span空标记。

<xsl:template match=
    "*[not(span) 
     and normalize-space()=''
      ]"/>

通过XSL输出。它移除所有空标签。

<p>In technical jargon, the expect<span class="insert">ed</span> excess return on a factor is proportional to the negative of the factor covariance with the pricing kernel, given by marginal utility of consumption for a representative agent.</p>

但只删除span空标签。所以我需要下面的XML

<p>In technical jargon<sup></sup>, the expect<span class="insert">ed</span> excess return on a factor is proportional to the negative of the factor covariance with the pricing kernel, <br/>given by marginal utility of consumption for a representative agent.</p>

谢谢你提前。

Answer 1

使用

<xsl:template match=
        "*[self::span 
        and normalize-space()=''
        ]"/>

Answer 2

如果只想删除span，则使模板仅匹配跨范围。

<xsl:template match="span[not(span) 
     and normalize-space()='']"/>
