XML Skip 'wrong' event type - php

Question

I have a certain BLOATED XML file that i use to generate a Gallery with some few information about the Picture. Besides of the Actual needed NEW there are plenty of entries with OLD, adding more pictures, but creating also duplicate entries.
<result>
<event>
<date>2015-04-14T22:19:02+02:00</date>
<type>OLD</type>
<value1>AAA</value1>
<id>changingIDwhatever</id>
<profile>
<url>/domainpart/SPECIFICNAME/?w=</url>
<name>SPECIFICNAME</name>
<value2>BBB</value2>
<value3>CCC</value3>
<value4>DDD</value4>
<image>

<width>320</width>

</profile>
</event>
<event>
<date>2015-04-14T22:19:02+02:00</date>

</profile>
</event>
</result>
I do generate everything in a pretty neat layout in a very basic way. As i have really NO knowledge at all about php, i usually base on skriptpieces i find that are kind of put together in a way that the outcome mostly is the way i need it.
<?php
//###################Config Start#########################
$memberid = "123456";
$maxAnzahl = 50;
$zaehler = 0;
$baseURL = "http://www.domain.tld";
//###################Config End#########################
$feed = simplexml_load_file('http://key:keypass#www.domain.tld/news/xml');
$events = $feed->events;
foreach ($events->event as $event) {
echo "<div class='4u'>";
echo "<article class='box style2'>";
if ($event->type == "newMember") {
echo "<a href='".$baseURL.$event->profile->url.$memberid."' class='image featured' target='_blank'><img src='" . $event->profile->image->url . "' alt='' /> </a>";
} else {
echo "<a href='".$baseURL.$event->profile->url.$memberid."' class='image featured' target='_blank'><img src='" . $event->image->url . "' alt='' /> </a>";
}
echo "<h3><a href='".$baseURL.$event->profile->url.$memberid."'>" . $event->profile->name . "</a></h3>";
echo "</article>";
echo "</div>";
$zaehler = $zaehler + 1;
if ($zaehler == $maxAnzahl) {
break;
}
}
?>
Would be someone able to tell me how i could specify now in that skript how to SKIP all OLD ?
Kind Regards

Answer 1

I have found the solution myself sigh I was blind to it, till i got the first reply, checked my question AGAIN and saw a marker that I normally wanted to change everywhere to make it CLEAR what i needed.
In my initial question was a line "if ($event->type == "newMember") {" Normally i had to change it to "NEW" like in my example, to help ppl who wanted to help, to see it more easy.... Well, now i saw it and it made everything clear to me.
Changing the code like:
<?php
//###################Config Start#########################
$memberid = "123456";
$maxAnzahl = 50;
$zaehler = 0;
$baseURL = "http://www.domain.tld";
//###################Config End#########################
$feed = simplexml_load_file('http://key:keypass#www.domain.tld/news/xml');
$events = $feed->events;
foreach ($events->event as $event) {
if ($event->type == "NEW") {
echo "<div class='4u'>";
echo "<article class='box style2'>";
echo "<a href='".$baseURL.$event->profile->url.$memberid."' class='image featured' target='_blank'><img src='" . $event->profile->image->url . "' alt='' /> </a>";
echo "<h3><a href='".$baseURL.$event->profile->url.$memberid."'>" . $event->profile->name . "</a></h3>";
echo "</article>";
echo "</div>";
} else {
echo "";
}
$zaehler = $zaehler + 1;
if ($zaehler == $maxAnzahl) {
break;
}
}
?>
Gives me exactly the Images and Content i was looking for. For some reason i had already the solution in the code, but it was somehow messed up.
Thank you anyways for the help and thoughts!

Answer 2

For this kind of tasks like query the XML structure I prefer to use XPATH.
Try like this. I hope works for you.
<?php
// Get the XML
//###################Config Start#########################
$memberid = "123456";
$maxAnzahl = 50;
$zaehler = 0;
$baseURL = "http://www.domain.tld";
//###################Config End#########################
$source = file_get_contents('http://key:keypass#www.domain.tld/news/xml');
// DOM document Creation
$doc = new DOMDocument;
$doc->loadXML($source);
// DOM XPath Creation
$xpath = new DOMXPath($doc);
// Get all NEW events ONLY
$events = $xpath->query('//result/event[text()="NEW"]');
// Count number of events
printf('There is %d events<br />', $events->length);
// List all events
for($i = 0; $i < ($events->length); $i++) {
$event = $events->item($i);
}
?>

You can introduce a condition right at the beginning of your foreach-loop that checks if the actual $event entry is to be skipped (filtered-out) and if so, skip to the next entry in loop:
foreach ($events->event as $event) {
$skip = $event->type != 'NEW';
if ($skip) {
continue;
}
...
Please see continue (and its sister break) to control loop structures in PHP.
