Для тех, кто наткнулся на этот вопрос и также может использовать ответ, я приведу пример разбора HTML в блоках [code].Хотя выглядит немного грязно:
<cfset contents = form.yourString />
<cfset substring1= "[code]" />
<cfset occurrences1 = ( Len(contents) - Len(Replace(contents,substring1,"","ALL"))) / Len(substring1) />
<cfset substring2= "[/code]" />
<cfset occurrences2 = ( Len(contents) - Len(Replace(contents,substring2,"","ALL"))) / Len(substring2) />
<cfif occurrences1 EQ occurrences2 AND occurrences1 GT 0 AND occurrences2 GT 0>
<cfset loopinstance = occurrences1 />
<cfelse>
<cfif occurrences1 LT occurrences2>
<cfset loopinstance = occurrences1 />
<cfelse>
<cfset loopinstance = occurrences2 />
</cfif>
</cfif>
<cfloop index="code_loop" from="1" to="#loopinstance#">
<cfscript>
// prepare variables //
code_string = contents;
startpos = FindNoCase("[code]", code_string);
startpos = Evaluate(startpos + 6); // adjust the correct position of string in question
endpos = FindNoCase("[/code]", code_string);
code_string = Mid(code_string, startpos, Evaluate(endpos - startpos)); // extract the string between code brackets
//** Replace-Codes are extensible depending on the used programming languages **//
code_string = ReplaceNoCase(code_string, "<","<", "ALL");
code_string = ReplaceNoCase(code_string, ">",">", "ALL");
//** process conversion of [code] block **//
startpos = FindNoCase("[code]", contents); // reevaluating the start and end positions for main string
startpos = Evaluate(startpos + 6); // adjust the correct position of form string
endpos = FindNoCase("[/code]", contents);
contents = RemoveChars(contents, startpos, Evaluate(endpos - startpos)); // remove the extracted string
contents = Insert(code_string, contents, Evaluate(startpos - 1)); // insert the processed code block to the original position
contents = ReplaceNoCase(contents, "[code]", "[coded]", "ONE"); // "flagging" the processed [code] block as finished by adding a "d"
contents = ReplaceNoCase(contents, "[/code]", "[/coded]", "ONE"); // "flagging" the processed [code] block as finished by adding a "d"
</cfscript>
</cfloop>
<!--- This is the regex to turn a written [code] block into an escaped HTML block --->
<cfscript>
contents = REReplaceNoCase(contents, "\[coded\](.*?)\[/coded\]", "<div id =""code_test"">Escaped Code: <br />\1</div>", "ALL");
</cfscript>
Я надеюсь, что это поможет некоторым людям, которым трудно следовать за помощью Дэвида Фабера.
