Report and HTML content

Question

Hi,
I have a lot of HTML formatted text stored in a blob field.
The HTML code has some <b>a href</b> tags (something like this: a href = "53127" or a href = "53127_1" or a href = "53127_2" ...).
I created a appIication using APEX (10gXE) and I can display the HTML content in my report but the links do not work.
I need something like this:
http://127.0.0.1:8080/apex/f?p=103:4:SESSION_ID::NO:RP,:P4_CODACT:53127
instead of:
http://127.0.0.1:8080/apex/53127
I am tryng to migrate a web application created in Java using servlets. In Java the solution was the use of regular expressions to convert the stored <b>a href</b> tag to a valid url.
Here is my Java code:
-- some code
        s=processHtmlTags(s,
            "<a href = \"([0-9_].*?)\">",
            "<a href=\"" + dm.response.encodeURL("ResultDetail") + "?codact=",
            "\">");-- rest of servlet
-- the processHtmlTags definition
    public String processHtmlTags(String INPUT, String REGEX, String strHead, String strTail) {
        int cnt=0;
        String strOutput;       
        Pattern pattern;
        Vector group0 = new Vector(5);
        Vector group1 = new Vector(5);       
        try {
            pattern = java.util.regex.Pattern.compile(REGEX);
            matcher = pattern.matcher(INPUT);
        catch(java.util.regex.PatternSyntaxException pse) {
        while (matcher.find()) {           
            group0.addElement(matcher.group(0));
            group1.addElement(matcher.group(1));
            cnt++;
        strOutput=INPUT;
        for(int i=0; i<group0.size(); i++) {           
            String s0=(String)group0.elementAt(i);
            String s1=(String)group1.elementAt(i);
            strOutput=strOutput.replaceAll(s0,strHead+strAnchor(s1)+strTail);           
        return strOutput;
    }The question is can I do the same thing using APEX?
Thanks,

Answer 1

Use the REGEXP_REPLACE function available in 10g.
That also implies switching from an HTML region to a PL/SQL region.
