RE: Help with emacs scripting

A concrete example always makes vague requirements clearer.
Thank you.

I think the following will do what you want.
The process is this: 
1. Go through the XSL buffer(s), 
2. sweeping the strings of interest and
3. type C-cC-c to process.
4. Move on to the next string and repeat.

(defvar *ds-languages-dir* "languages")
(defvar *ds-php-file* (format "%s/pt.php" *ds-languages-dir*))
(defvar *ds-php-buffer* ())

(defun  ds-create-lang-entries ()
  "Change the selection in the current buffer and create a PHP definition in 
the PHP file.
The change to make is
    \'MATCHED_STRING\'
         --> \'<xsl:value-of select=\"/xml/lang/MATCHED_STRING\" />\'.
The addition to the PHP file is made at the end of the file;
it is \'DEFINE(\"_LANG_MATCHED_STRING\", \"bar\");\'."
  (interactive)
  (ensure-php-buffer)
  (let* ((xsl-format "<xsl:value-of select=\"/xml/lang/%s\" />")
         (php-format "DEFINE(\"_LANG_%s\", \"bar\");\n")
         (the-string (buffer-substring-no-properties (point) (mark)))
         (the-STRING (upcase the-string)))
    ;; Change the selected text to the appropriate XSL
    (delete-region (point) (mark))
    (goto-char (mark))
    (insert (format xsl-format the-string))
    ;; Now add a PHP definition at the end of the PHP file.
    (save-excursion
      (set-buffer *ds-php-buffer*)
      (goto-char (point-max))
      (insert (format php-format the-STRING)))))

(defun ensure-php-buffer ()
  "Make sure that everything about the PHP buffer is good."
  (unless (file-directory-p *ds-languages-dir*) (make-directory 
*ds-languages-dir* t))
  (unless *ds-php-buffer* (setq *ds-php-buffer* (find-file-noselect 
*ds-php-file*))))

(local-set-key "\C-c\C-c" 'ds-create-lang-entries)

I hope this helps.

I'm majoring in applied math and computation, I know pretty well that computers 
are dumb xD

I think neither of you have understood what I wanted, so I'll give you an 
example.
I have a lot of .xsl that generate pages and I want to make those pages 
translatable. I migth have the file, for exemple, welcome.xsl:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";> 
<xsl:output method="html" indent="yes" encoding="iso-8859-1" />
<xsl:template match="/">
<xsl:if test="welcome">
<p>Bem-vindo</p>
</xsl:if>
<ul>
<xsl:for-each select="elements">
<li>Coisa <xsl:value-of select="name" /></li>
</xsl:for-each>
</ul>
</xsl:template>
</xsl:stylesheet>
And I wanted to make this translatable, so I change this to
<?xml version="1.0" encoding="ISO-8859-1" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";> 
<xsl:output method="html" indent="yes" encoding="iso-8859-1" />
<xsl:template match="/xml">
<xsl:if test="welcome">
<p><xsl:value-of select="/xml/lang/_WELCOME" /></p>
</xsl:if>
<ul>
<xsl:for-each select="elements">
<li> <xsl:value-of select="/xml/lang/_STUFF" />  <xsl:value-of select="name" 
/></li>
</xsl:for-each>
</ul>
</xsl:template>
</xsl:stylesheet>
And I create a languages/pt.php with:
 define('_LANG_WELCOME','Bem-vindo'); 
 define('_LANG_STUFF','Coisa');

I have a piece of php code that puts in the xml all the constants that begin 
with "_LANG".

I have a lot of these .xsl and I need to go manually through them all to find 
the strings that I want to make translatable. What I want this script to do is, 
on my input put that <xsl:value-of select="/xml/lang/_STUFF" /> thing on the 
place I select and append to the language file the repective define();.
