是否有正则表达式或任何替换以下内容的方法:

  some content...<span style='color:red'>t</span><span style='color:red'>e</span><span style='color:red'>s</span><span style='color:red'>t</span> some content

用这个?

some content... <span style='color:red'>test</span> some content

如果HTML标记完全相同,您只需使用String.replace

var oldStr = "<span style='color:red'>t</span><span style='color:red'>e</span><span style='color:red'>s</span><span style='color:red'>t</span>";
var newStr = oldStr.replace("</span><span style='color:red'>", "");

有观点认为不应使用正则表达式来处理HTML。

如果您同意,可以使用以下XSLT转换。

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
  <xsl:output method="html" doctype-public="XSLT-compat"
    encoding="UTF-8" indent="yes" />
  <xsl:strip-space elements="*"/>

  <xsl:template match="span">
    <xsl:copy>
      <!-- Copy attributes and text from the current span -->
      <xsl:apply-templates select="@*|node()"/>
      <xsl:variable name="nextSpans" select="following-sibling::span"/>
      <!-- Copy text from following spans -->
      <xsl:for-each select="following-sibling::node()">
        <xsl:variable name="ind" select="position()"/>
        <xsl:if test="generate-id()=generate-id($nextSpans[$ind])">
          <xsl:value-of select="."/>
        </xsl:if>
      </xsl:for-each>
    </xsl:copy>
  </xsl:template>

  <!-- Switch off processing of "following" spans -->
  <xsl:template match="span[preceding-sibling::node()[1]/name()='span']"/>

  <xsl:template match="@*|node()">
    <xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
  </xsl:template>
</xsl:stylesheet>
