                    Add to .vimrc so you can comment blocks of text in perl/java/etc.

Highlight a block of text and hit ,# and it is commented out in perl.

                    Preview what you type in an input or a textarea out of them (in a html tag, like a p, hx...)

Seen here: (spanish explain).

javascript code:

function preview(id1, id2){
	  		var NewText = document.getElementById(id1).value;
	  		splitText = NewText.split(/\n/).join("<br />");
	  		var DivElement = document.getElementById(id2);
	  		DivElement.innerHTML = splitText;

html code:

<form action="#">
<input type="text" id="nombre" onkeyup="preview('name', 'preview-name');" />

<input type="text" id="phone" onkeyup="preview('phone', 'preview-phone');" />

	<dd id="preview-name"></dd>
	<dd id="preview-phone"></dd>

                    This function transforms an HTTP request path (ie, $_SERVER['PATH_INFO']) into its canonical form, removing empty path elements and relative path elements (//, /./, /../). It assumes that there is a trailing slash on the path if it's a directory.

function canonical_path($path) {
    $canonical = preg_replace('|/\.?(?=/)|','',$path);
    while (($collapsed = preg_replace('|/[^/]+/\.\./|','/',$canonical,1)) !== $canonical) {
        $canonical = $collapsed;
    $canonical = preg_replace('|^/\.\./|','/',$canonical);
    return $canonical;
                    The following code is for loading Velocity resources (i.e. Velocity files) from a web application's ServletContext.


import javax.servlet.ServletContext;

import org.apache.commons.collections.ExtendedProperties;
import org.apache.velocity.exception.ResourceNotFoundException;
import org.apache.velocity.runtime.resource.Resource;
import org.apache.velocity.runtime.resource.loader.ResourceLoader;

public class WebAppResourceLoader extends ResourceLoader {

    private static ServletContext context = null;

    public void init(ExtendedProperties extendedProperties) {


    private static ServletContext getServletContext() {
        return context;

    public static void setServletContext(ServletContext context) {
        WebAppResourceLoader.context = context;

     * @see org.apache.velocity.runtime.resource.loader.ResourceLoader#getResourceStream(java.lang.String)
    public InputStream getResourceStream(String name)
            throws ResourceNotFoundException {
        InputStream result = null;

        if (name == null || name.length() == 0) {
            throw new ResourceNotFoundException("No template name provided");

        try {
            if (!name.startsWith("/"))
                name = "/" + name;

            result = getServletContext().getResourceAsStream(name);
        } catch (NullPointerException npe) {
            throw new ResourceNotFoundException("ServletContext not found");
        } catch (Exception fnfe) {
            throw new ResourceNotFoundException(fnfe.getMessage());

        return result;

    public boolean isSourceModified(Resource arg0) {
        return false;

    public long getLastModified(Resource arg0) {
        return 0;


Then to initialize Velocity:

    Properties props = new Properties();
    props.setProperty("resource.loader", "webapp");
        "Load from the ServletContext");

From then on out you can use #parse directives such as:

Explain will tell you if your index work as you thought.

(I forgot to login in the last two snippets)                
                    Here is a quick way to convert database records to XML using XML::Simple.


use warnings;
use strict;
use XML::Simple;
use DBI;

my $dbh = DBI->connect('DBI:mysql:MYDATABASE','user','password')
  or die DBI->errstr;

# Get an array of hashes
my $recs = $dbh->selectall_arrayref('SELECT * FROM contents',{ Columns => {} });

# Convert to XML where each hash element becomes an XML element
my $xml = XMLout( {record => $recs}, NoAttr => 1 );

print $xml;


For a table with fields named "id", "entry", and "modified", the output would be:

    <entry>1932 - 1939</entry>
    <modified>2005-04-15 22:24:44</modified>
    <entry>Yet another entry</entry>
    <modified>2005-04-15 22:25:00</modified>
    <entry>More stuff here</entry>
    <modified>2005-04-15 22:25:13</modified>
