[jdom-interest] Text replacement

Fri May 5 16:14:23 PDT 2006

First of all, thanks everybody for your help!
And sorry about the reply for your email, I didn't see it.

OK, here is an example of my template:

<html>
...

<brtpchamada id="1">
   <a href="#" onclick="javascript:open('$LINK');">
      <brtpolho/>
   </a>
</brtpchamada>

<div class="px18"> </div>

<brtpchamada id="2">
   <brtptitulo open="yes"/>
   <a href="$LINK">
      $LINK
   </a>
</brtpchamada>

..

</html>

So, as you can see, I have <brtpchamada>, <brtpolho> and <brtptitulo>
proprietary tags. These are responsable to map where and what kind of
data should be there.
I use to have a <brtplink> to indicate where where I should create the
<a href="">. But now I need to worry about javascript's, inside every
tag (<img>, <a>, etc), and in the text of all elements. Actually, all
elements that are inside the <brtpchamada> tag. Thats where come the
context problem: the $LINK in the <brtpchamada> with id="1" is
diferente from the $LINK in the <brtpchamada> with id="2". So, to
create the replacement list, I do this:

HashMap replacement = new HashMap();

Iterator chamadaIterator = root.getDescendants(new
ElementFilter("brtpchamada"));
while (chamadaIterator.hasNext()) {
    // read stuf from the database for this chamada, with id = 1 or id
= 2 for this example

    // ElementStartsFilter is a new filter that I created to filter,
as the name says, only
    // elements that starts with "brtp".
    Iterator filhosIterator = chamadaTagAtual.getDescendants(new
ElementStartsFilter("brtp"));
    while (filhosIterator.hasNext()) {
        Element filhoTagChamadaAtual = (Element) filhosIterator.next();
        Element conteudoTag = new Element("abc");

        // do some processing here, acording to this <chamada> tag,
and modify conteudoTag

        replacement.put(filhoTagChamadaAtual, conteudoTag);
    }
}

// This funcion replaces the key of the hashmap for the value in the document
replaceAllTags(replacement);

Now is the trick part: for every content inside the <chamada> tag, I
need to replace $LINK for a SPECIFIC url to this <brtpchamada> (id = 1
or id = 2 in this template that I used for example).

Now, how can I do that? Or am I freaking out the porpouse of getDescendents? :-)

After Thomas reply, I thought about to do somenthing like this (of
course I will need to learn the java.util.regex.* first ;-)

String document = LoadFile("document.tpl");

// supose for a minute that its like perl :-)
while(document.matches("<brtpchamada>(.+)</brtpchamada>")){
    String content = document.lastMatch();
    content.replaceAll("<brtptitulo\>", getDataForThis());
    content.replaceAll("LINK", getLinkForThis());
    // etc
    document.replaceAll("<brtpchamada>(.+)</brtpchamada>", contet);
}

but the problem here is that I would need to grep all atributes, to
get <brtpchamada id="1"> id for example, replace empty tags or not
empty tags (<brtptitulo/> could be <brtptitulo>...</brtptitulo> for
example), and do all that stuff that I think jdom does much better
then I do...

I hope I was more clear at this time.

Best reagards and thanks again,
Leonardo Barbosa
