在一个元素中获取XML内容并将结果与​​其他子元素分开

Question

I work with xml file that looks like this:

<text>
  <paragraph/>
    First text
  <paragraph/>
    Second text
</text>
<text>
  <paragraph/>
    Third text
  <paragraph/>
    Fourth text
</text>

I need to get the value of text element but the result should be in 4 rows. So every <paragraph/> element starts new row:

1 | First text
2 | Second text
3 | Third text
4 | Fourth text

My code:

$filexml = File::get('../file.xml');

$xml = simplexml_load_string($filexml);

for ($i=1; $i < count($xml->text) + 1; $i++) {

    foreach ($xml->text as $text_item) {
        echo $i++." | ".$text_item."<br/>";
    }

}

My result:

1 | First text Second text
2 | Third text Fourth text

What should I do next? Or maybe there is different approach how can I achieve the desired result?

Answer 1

You could use DOMDocument and DOMXPath. In the expression you could get the text nodes using text().

Then you could loop those and check for empty strings.

$filexml = File::get('../file.xml');
$doc = new DOMDocument();
$doc->loadXML($filexml);
$xpath = new DOMXpath($doc);
$i = 1;
$expression = "//text/text()";
foreach ($xpath->query($expression) as $text) {
    $result = trim($text->nodeValue);
    if ($result !== "") {
        echo sprintf("%d | %s<br>", $i++, $result);
    }
}
