If you require the input to be valid xml, then you can also use an XSL
transformation:
<cfset text = REReplaceNoCase(text,'target="[^"]*"',"","ALL")>
<cfset text = ReplaceNoCase(text,"<a ",'<a target="_blank"',"ALL")>
Or
<cfsavecontent variable="xsl">
<xsl:stylesheet>
<xsl:output type="xml" />
<xsl:template match="*">
<xsl:copy>
<xsl:copy-of select="@*" />
<xsl:apply-templates />
</xsl:copy>
</xsl:template>
<xsl:template match="*[translate(local-name(),'A','a')='a']">
<xsl:copy>
<xsl:copy-of select="@*" />
<xsl:attribute name="target">_blank</xsl:attribute>
<xsl:apply-templates />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
</cfsavecontent>
<cfset text = XMLTransform(XMLParse(text),xsl)>
It's more code yes, but if you're requiring XML content, this will be
more bullet-proof than the regular expression solution. On CF7 you can
put the XSL sheet in a separate template and just use the absolute
path to the file in the XMLTransform function, i.e.:
<cfset text =
XMLTransform(XMLParse(text),expandPath("target_blank.xsl"))>
