Stringa meklēšana iekš *.xml atribūtiem..

[SadDemon]

*.xml saturs ir:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Noliktava produkcijai="----">
<product id="1" amount="2" name="test" color="test" article="-" category="citi" status="ir" catalog="test" page="-" price="-" />
<product id="2" amount="7" name="vizītkaršu etvija" color="metāls" article="50042" category="birojam" status="ir" catalog="Reflect" page="87" price="2.64" />
<product id="3" amount="25" name="vizītkaršu etvija" color="metāls" article="ap802301" category="birojam" status="ir" catalog="Anda Present" page="39" price="1.16" />
<product id="4" amount="127" name="vizītkaršu etvija" color="metāls" article="1602270" category="birojam" status="ir" catalog="Marksmans (vecais)" page="-" price="2.19" />
</Noliktava>

 

un *.php saturs ir:

<?php

$amount_input = '2';
$name_input = '';
$category_input = '';
$status_input ='';

$doc = new DOMDocument;
$doc -> load('../xml/depot.xml');

$content = array();
$products = $doc -> getElementsByTagName('product');

foreach ($products as $product) {
$id = $product -> getAttribute('id');
$amount = $product -> getAttribute('amount');
$name = $product -> getAttribute('name');
$color = $product -> getAttribute('color');
$article = $product -> getAttribute('article');
$category = $product -> getAttribute('category');
$status = $product -> getAttribute('status');

if(ereg($amount_input, $amount)) {
	$row = "<"."product id=\"".$id."\" amount=\"".$amount."\" name=\"".$name."\" color=\"".$color."\" article=\"".$article."\" category=\"".$category."\" status=\"".$status."\" />"."<br>";
	$content[$id] = $row;	
}
}

ksort($content);

foreach ($content as $output) {
echo $output;	
}

?>

 

Problēma Nr.1 - ja meklējamais ir "2" starp amount atribūtiem, tad atrodam.. "2", "25" un "127".. bet nepieciešams ir tikai "2" un "25".. tobiš, lai meklētu tikai no pirmā simbola..

 

Problēma Nr.2 - vajadzētu panākt, lai.. ja $amount_input nav tukš un pārējie ir, tad "ereg($amount_input, $amount)"..

ja $amount_input nav tukš un, piemēram, $category_input nav tukš.. tad "(ereg($amount_input, $amount) && ereg($category_input, $category))"..

 

 

Iepriekš pateicos par palīdzību!

1. es ir dumš ar tiem te, bet varbūt šādi?

$amount_input = '^[2]';

ja tas ko gribi panākt, ir meklēt pēc "sākot ar..", tad tur pat regex nevajag - strpos($amount , '2') === 0
