Question

这是我的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>

我的代码迭代所有列：

$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 />';
    }
}

现在输出最奇怪。我不明白为什么'#text =＆gt;'不断出现在那里：

#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 =>

Answer 1

您是否尝试使用LIBXML_NOBLANKS选项load()？

或者loadXML()也可以做你想做的事（我在这里猜测）。

根据PHP, DOM and XML : Part 2 – DOMDocument，您应该：

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

或者

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

取决于您的PHP版本。

Answer 2

您可以跳过DOMText元素：

$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 />';
        }
    }
}

或者使用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";
}

Answer 3

<?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>";
}
?>

尝试这个...它不是通过贬低标准和bla bla bla或类似的东西，但它的工作原理！：P
