Building XML Trees With PHP - A La Carte

(Page 4 of 11 )

Here's another example, this one building a slightly more complicated document tree,

<?php
// include class
include("XML/Tree.php");
// instantiate object
$tree 
= new XML_Tree();
// add the root element
$root =& $tree->addRoot("recipe");
// 
add children
$name =& $root->addChild("name", "Chicken Tikka");
$author =& 
$root->addChild("author", "Anonymous");
$ingredients =& $root->addChild("ingredients");
$servings 
=& $root->addChild("servings", 3);
$process =& $root->addChild("process");
// 
create array of ingredients
$ingredientsArray = array(
"Boneless chicken breasts, 
2", 
"Chopped onions, 2", 
"Garlic, 1 tsp",
"Ginger, 1 tsp",
"Red 
chili powder, 1 tsp",
"Lime juice, 2 tbsp",
"Butter, 2 tbsp"
);
// 
create 
array of steps to execute recipe
$stepsArray = array(
"Cut chicken 
into 
cubes, 
wash and apply lime juice and
salt",
"Add ginger, garlic, chili 
and 
lime juice 
in a separate
bowl",  
"Mix well, and add chicken to marinate 
for 
3-4 hours",
"Place 
chicken pieces on skewers and barbeque", 
"Remove, 
apply 
butter, and barbeque 
again until meat is
tender",
"Garnish with lemon 
and chopped 
onions"
);
// 
add ingredient list to tree
foreach ($ingredientsArray 
as $i)
{
$item 
= $ingredients->addChild("item", 
$i);
}
// add execution steps 
to tree 
foreach 
($stepsArray as $s)
{
$step = 
$process->addChild("step", 
$s);
}
// 
print tree
$tree->dump();
?>

and here's the output:

<?xml version="1.0"?>
<recipe>
<name>Chicken Tikka</name>
<author>Anonymous</author>
<ingredients>
<item>Boneless chicken breasts, 2</item>
<item>Chopped 
onions, 2</item>
<item>Garlic, 1 tsp</item>
<item>Ginger, 
1 tsp</item>
<item>Red chili powder, 1 tsp</item>
<item>Lime 
juice, 2 tbsp</item>
<item>Butter, 2 tbsp</item>
</ingredients>
<servings>3</servings>
<process>
<step>Cut 
chicken into 
cubes, wash and apply lime juice and
salt</step>
<step>Add 
ginger, 
garlic, chili and lime juice in a separate
bowl</step>
<step>Mix 
well, 
and add chicken to marinate for 3-4
hours</step>
<step>Place 
chicken 
pieces on skewers and barbeque</step>
<step>Remove, apply 
butter, 
and barbeque again until meat is
tender</step>
<step>Garnish 
with 
lemon and chopped onions</step>
</process>
</recipe>
