Perform search and replace in a custom command?

Question

Hello,
Does anyone know how to perform a search and replace for selected text in a custom command?
My specific dilemma is this: I have a large document containing [very poorly formatted] songs. For example:
<p>Verse1 Verse1 Verse1 Verse1 Verse1</p>
<p>Verse1 Verse1 Verse1 Verse1 Verse1</p>
<p>Verse1 Verse1 Verse1 Verse1 Verse1</p>
<p>Chorus Chorus Chorus Chorus</p>
<p>Chorus Chorus Chorus Chorus</p>
<p>Chorus Chorus Chorus Chorus</p>
<p>Verse2 Verse2 Verse2 Verse2 Verse2</p>
<p>Verse2 Verse2 Verse2 Verse2 Verse2</p>
<p>Verse2 Verse2 Verse2 Verse2 Verse2</p>
<p>Verse3 Verse3 Verse3 Verse3 Verse3</p>
<p>Verse3 Verse3 Verse3 Verse3 Verse3</p>
<p>Verse3 Verse3 Verse3 Verse3 Verse3</p>
I would like to be able to select all the text in a verse and run my custom command on it that would remove the "<p>" and replace "</p>" with "<br />".
Thanks,
Kelso

replaceAll method in String is available only from 1.4 onwards.
http://java.sun.com/j2se/1.4.1/docs/api/java/lang/String.html#replaceAll(java.lang.String, java.lang.String).
You could use a method to search and replace a String with another...
public String replace (String source, String search, String replace) {
    StringBuffer result = new StringBuffer();
    int start = 0;
    int index = 0;
    while ((index = source.indexOf(search, start)) >= 0) {
      result.append(source.substring(start, index));
      result.append(replace);
      start = index + search.length();
    result.append(source.substring(start));
    return result.toString();
}
