PHP DOM odd output?

Question

Here is my XML:

<?xml version="1.0" encoding="UTF-8"?>
<columns>
    <column>
        <originalName>ORP</originalName>
        <name>ORP</name>
        <visible>1</visible>
    </column>
    <column>
        <originalName>OKRES</originalName>
        <name>OKRES</name>
        <visible>1</visible>
    </column>
    <column>
        <originalName>Objekt</originalName>
        <name>Objekt</name>
        <visible>1</visible>
    </column>
    <column>
        <originalName>Školenie</originalName>
        <name>Skolenie</name>
        <visible>1</visible>
    </column>
    <column>
        <originalName>Dátum posledného školenia OPP</originalName>
        <name>DatumPoslednehoSkoleniaOPP</name>
        <visible>1</visible>
    </column>
    <column>
        <originalName>Dátum posledného školenia OPP</originalName>
        <name>DatumPoslednehoSkoleniaOPP1</name>
        <visible>0</visible>
    </column>
</columns>

My code to iterate over all columns:

$schema = new DOMDocument();
$schema->load(BASE_PATH.'/schema.xml');
foreach ($schema->getElementsByTagName('column') as $column) {
    foreach($column->childNodes as $child) {
        echo $child->nodeName, ' => ', $child->nodeValue, '<br />';
    }
}

Now the output is most odd. I don't understand why the '#text =>' keeps appearing there:

#text =>
originalName => ORP
#text =>
name => ORP
#text =>
visible => 1
#text =>
#text =>
originalName => OKRES
#text =>
name => OKRES
#text =>
visible => 1
#text =>
#text =>
originalName => Objekt
#text =>
name => Objekt
#text =>
visible => 1
#text =>
#text =>
originalName => Školenie
#text =>
name => Skolenie
#text =>
visible => 1
#text =>
#text =>
originalName => Dátum posledného školenia OPP
#text =>
name => DatumPoslednehoSkoleniaOPP
#text =>
visible => 1
#text =>
#text =>
originalName => Dátum posledného školenia OPP
#text =>
name => DatumPoslednehoSkoleniaOPP1
#text =>
visible => 0
#text =>

You could skip the DOMText elements:

$schema = new DOMDocument();
$schema->load(BASE_PATH.'/schema.xml');
foreach ($schema->getElementsByTagName('column') as $column) {
    foreach($column->childNodes as $child) {
        if ($child instanceof DOMElement) { // (! $child instanceof DOMText)
            echo $child->nodeName, ' => ', $child->nodeValue, '<br />';
        }
    }
}

Or use DOMXPath:

$doc = new DOMDocument();
$doc->load(BASE_PATH.'/schema.xml');
$xpath = new DOMXPath($doc);

foreach($xpath->query('/columns/column/*') as $child)
{
    echo $child->nodeName, ' => ', $child->nodeValue, "\n";
}

Did you try and load() with the LIBXML_NOBLANKS option?

Alternatively loadXML() might do what you want (I'm guessing here).

According to PHP, DOM and XML : Part 2 – DOMDocument you should either:

$schema->load(BASE_PATH.'/schema.xml', LIBXML_NOBLANKS);

Or

$schema = new DOMDocument();
$schema->preserveWhiteSpace = false; // This is the important part
$schema->load(BASE_PATH.'/schema.xml');

Depending on your PHP version.

<?php
$schema = new DOMDocument();
$schema->load('schema.xml');
foreach ($schema->getElementsByTagName('column') as $column) {
    $array = false;$i=0;
    foreach ($column->childNodes as $childNode){
        $array[$i] = $childNode->firstChild->nodeValue;
        $i++;
    }
    echo $array[1]." = > ".$array[3]." = > ".$array[5]."<br>";
}
?>

try this one... its not by falowing standards and bla bla bla or something like that but it works! :P

p.s. here you have some explanations/tutorials if you want read...

Take a look at my schema, there is no '#text' element there whatsoever. It should not get printed.

FeRtoll Over a year ago

try with this print_r($child); and then you will se that there is #text :) (DOMText Object ( ) originalName => ORP), (DOMElement Object ( ) #text => )

FeRtoll Over a year ago

use echo $child->nodeValue."<br>"; and you will get it clean... dont know for what you need it!
