Question

这是我的PHP / XML代码。我只是想从这个搜索特定的$searchterm：

$doc = new DOMDocument;
$doc->load('authentication.xml');

$xpath = new DOMXPath($doc);

$searchTerm = "N0A097016646";

$lineNo = 0;
foreach ($xpath->query('//device/following::comment()') as $comment){
    $serial= $xpath->query('//device', $comment)->item($lineNo)->textContent;

    echo "Line number: ".$comment->getLineNo()." Device number: ".$serial." Comented number: ".$comment->textContent."<br>";

    $lineNo++;
}

我应该在哪里放$searchTerm变量来搜索该特定节点？

Answer 1

如您的问题所示，您无法使用$searchTerm。

与=（等于）

一起使用

text() = '$searchTerm'

代码：

$searchTerm = "N0A097016646";

foreach ($xpath->query("//device[text() = '$searchTerm']/following::comment()") as $comment){
    echo "Line number: ".$comment->getLineNo(). '<br/>'.
    " Device number: ".$searchTerm.'<br/>'.
    " Comented number: ". $comment->textContent."<hr>";
}

Sample Output

从XML搜索特定节点值
