如何在Coldfusion中使用正则表达式的过滤器

<cffunction name="regexExample" returntype="String">
    <cfset var regex = CreateObject("java", "java.util.regex.Pattern").compile("[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}")>
    <cfset var match = regex.matcher(argument)>
    <cfif match.find()>
        <cfreturn match.group(0)>
    <cfelse>
        <cfreturn "No match found">
    </cfif>
</cffunction>

<cfset var emailRegex = CreateObject("java", "java.util.regex.Pattern").compile("[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}")>
<cfset var text = "This is a sample text with email addresses john@example.com and jane@example.com">
<cfset var matches = text.match(emailRegex)>

<cfoutput>
<p>Found <cfif matches?count > 0>
    <cfloop from="1" to="#matches.length#" index="i">
        <span style="color: blue;">#matches[i]#</span>
    </cfloop>
</cfif>
</cfoutput>

<cfset var text = "This is a sample text with <b>HTML</b> tags and attributes">
<cfset var filter = createFilter(text, "regex", "[\r
\t
\f]+")>
<cfset var newText = removeFilter(filter, text)>

<cfoutput>
<p>#newText#</p>
</cfoutput>
