我正在使用rss提要来获取新闻项，然后使用XSLT将它们显示给用户。但是 rss 提要在描述节点中具有<br>标记。我想删除它们，以便文本正确换行。

有人可以帮我解决这个问题吗？如果您需要更多信息，请告诉我。
谢谢。
你能详细说明一下吗？
你所说的"<br> tags"实际上是无意义的<br>字符串（在XSLT方面毫无意义）。从说明中删除它们的唯一方法是使用字符串操作。如果使用的是 XSLT 1.0，则调用递归命名模板以删除字符串的所有匹配项 - 例如：
<xsl:template name="remove">
<xsl:param name="text"/>
<xsl:param name="searchString"/>
<xsl:choose>
<xsl:when test="contains($text,$searchString)">
<xsl:value-of select="substring-before($text,$searchString)"/>
<xsl:call-template name="remove">
<xsl:with-param name="text" select="substring-after($text,$searchString)"/>
<xsl:with-param name="searchString" select="$searchString"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
