XML-Verarbeitung, Bestellung und Looping

Question

Ich habe für 10 Tage zu kämpfen versuchen, eine XML-Feed zu machen:

http://feed.harjbains.gnomen-europe.com/xml-feed/

ich simplexml versucht haben, xmlDOM und XSLT alle Nuancen. Meine Programmierfähigkeiten sind im Moment ein wenig herausgefordert, ich weiß nicht, ob es die Medikamente sind, die mein Doktor mir gegeben hat, oder ich werde gerade alt und sollte den Hacking-Code aufgeben.

Ich habe in mehrdimensionale Arrays, JSON und XML-Stylesheets geschaut, XSLT ist sehr langweilig, mag nicht mein XML und stört mein Stylesheet.

Ich möchte die XML machen können, indem sie die Anzeige entweder date_updated oder Preis bestellen, die Begrenzung der Ergebnisse durch Status und der Lage sein, die Anzahl der Datensätze zu n zu begrenzen.

Hier ist mein Code, um jedes Element in ein Array zu platzieren, aber ich kann keine Sortierung so machen.

<?php 
    $xml = simplexml_load_file("http://feed.harjbains.gnomen-europe.com/xml-feed/"); 

    $properties = $xml; 

    $id    = array(); 
    $beds   = array(); 
    $baths   = array(); 
    $price   = array(); 
    $address1  = array(); 
    $area   = array(); 
    $postcode  = array(); 
    $date_updated = array(); 
    $transaction = array(); 
    $status   = array(); 
    $image   = array(); 
    $img   = array(); 
    $description = array(); 

    $i=0; 
    $totrecs=0; 
    foreach ($properties as $property) { 
     $i=$i+1; 
     $address[$i]  = $property->address1; 
     $id[$i]   = $property->id; 
     $beds[$i]   = $property->beds; 
     $baths[$i]  = $property->baths; 
     $price[$i]  = $property->price; 
     $address1[$i]  = $property->address1; 
     $area[$i]   = $property->area; 
     $postcode[$i]  = $property->postcode; 
     $date_updated[$i] = $property->date_updated; 
     $transaction[$i] = $property->transaction; 
     $status[$i]  = $property->status; 
     $image[$i]  = $property->image; 
     $description[$i] = $property->description; 
     $totrecs   = count($id); 

     if(isset($property->image->img)) { 
      //echo $address1[$i]."<BR>"; 
      $image[$i] = true; 
      $x=0; 
      foreach($property->image->img as $a) { 
       $img[$i][$x]= $a; 
       //echo $img[$i][$x]."<BR>"; 
       $x=$x+1; 
      } 
     } else { 
      $image[$i] = false; 
     } 
    } 
?>

XSLT Reconsider da es eine Methode sort beibehält. Zur Veranschaulichung transformiert unten der ursprüngliche XML-Feed in ein XML mit Eigenschaften, sortiert nach Preis in absteigender Reihenfolge, wählt nur bestimmte Elemente aus, Filter auf die ersten 5 (< entspricht <) und nur Elemente mit status = 'Let'.

XSLT(speichern als XSL-Datei oder eingebetteten PHP-String)

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
<xsl:output omit-xml-declaration="yes" indent="yes" /> 
<xsl:strip-space elements="*"/> 

<xsl:template match="/properties"> 
    <xsl:copy> 
     <xsl:apply-templates select="property[position() &lt; 6 and status='Let']"> 
      <xsl:sort select="translate(price, ',', '')" data-type="number" order="descending"/> 
     </xsl:apply-templates> 
    </xsl:copy> 
</xsl:template> 

<xsl:template match="property"> 
    <xsl:copy> 
    <xsl:copy-of select="id|beds|baths|price|address1|area|postcode|date_updated|transaction|status|image|img|description"/> 
    </xsl:copy> 
</xsl:template> 

</xsl:stylesheet> 

PHP(sicher sein, php-xsl Erweiterung aktiviert in INI-Datei haben)

<?php 

// LOAD XML FEED 
$xml = simplexml_load_file("http://feed.harjbains.gnomen-europe.com/xml-feed/"); 

// LOAD XSLT SCRIPT 
$xsl = new DOMDocument; 
$xsl->load('XSLT_Script.xsl'); // OR $xsl->loadXML($xslstring); 

// INITIALIZE TRANSFORMER 
$proc = new XSLTProcessor; 
$proc->importStyleSheet($xsl);  

// TRANSFORM SOURCE TO NEW TREE 
$newXML = $proc->transformToXML($xml); 

// ECHO OUTPUT 
echo $newXML; 

// SAVE OUTPUT TO FILE 
file_put_contents('Output.xml', $newXML); 

?>
