Question

我一直在使用以下内容解析xml文件，但现在进入一种情况，其中可能有多个项目而不是一个可能的值。我需要能够将它们保存到数组中，以便可以在它们上运行foreach循环。在这种情况下，我不想使用simplexml，因此，不建议您-我想使该方法与我做过类似操作的其他地方相同-这种情况下可能会发送多个项目。

这是我过去经常使用的方法，当只有一个名称/值时，它可以很好地工作：

public static BufferedImage text2Image(Font font, Color textColor, Color backgroundColor, String...textRows) {
    BufferedImage helperImg = new BufferedImage(1, 1, BufferedImage.TYPE_INT_RGB);
    Graphics2D g2d = helperImg.createGraphics();

    g2d.setFont(font);
    FontMetrics fm = g2d.getFontMetrics();

    int width = 0;
    for(String row : textRows) {
        if(fm.stringWidth(row) > width) {
            width = fm.stringWidth(row);
        }
    }
    int height = fm.getHeight() * textRows.length;
    g2d.dispose();

    BufferedImage finalImg = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);

    g2d = finalImg.createGraphics();
    g2d.setColor(backgroundColor);
    g2d.fillRect(0, 0, width, height);
    g2d.setRenderingHint(RenderingHints.KEY_ALPHA_INTERPOLATION, RenderingHints.VALUE_ALPHA_INTERPOLATION_QUALITY);
    g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
    g2d.setRenderingHint(RenderingHints.KEY_COLOR_RENDERING, RenderingHints.VALUE_COLOR_RENDER_QUALITY);
    g2d.setRenderingHint(RenderingHints.KEY_DITHERING, RenderingHints.VALUE_DITHER_ENABLE);
    g2d.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS, RenderingHints.VALUE_FRACTIONALMETRICS_ON);
    g2d.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
    g2d.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
    g2d.setRenderingHint(RenderingHints.KEY_STROKE_CONTROL, RenderingHints.VALUE_STROKE_PURE);
    g2d.setFont(font);
    fm = g2d.getFontMetrics();
    g2d.setColor(textColor);
    int y = fm.getAscent();
    for(String row : textRows) {
        g2d.drawString(row, 0, y);
        y += fm.getHeight();
    }
    g2d.dispose();

    return finalImg;
}

这是存储在something.txt中发送的内容的一个示例，我将它保存到其中：

//receive the xml and trim
$xml_post = trim(file_get_contents('php://input'));

//save posted xml to file to ensure correct post values
file_put_contents($_SERVER['DOCUMENT_ROOT'].'/../something/something.txt', print_r($xml_post, true));

//open domdocument
$xml = new DOMDocument();

//load xml
$xml->loadXML($xml_post);

//parse the XML into a usable array
$xmlval = array();

//these are all fine because there can only be one value sent
$xmlval['orderid'] = $xml->getElementsByTagName("orderid")->item(0)->nodeValue;
$xmlval['test'] = $xml->getElementsByTagName("test")->item(0)->nodeValue;
$xmlval['referrer'] = $xml->getElementsByTagName("referrer")->item(0)->nodeValue;

//******these can be repeated so I need to figure out how to save these as an array in something like $xmlval['items'] so I can run a foreach loop - foreach($xmlval['items'] as $item) and access like $item['productname'] and so on for each group

$xmlval['productname'] = $xml->getElementsByTagName("productname")->item(0)->nodeValue;
$xmlval['quantity'] = $xml->getElementsByTagName("quantity")->item(0)->nodeValue;
$xmlval['returnprice'] = $xml->getElementsByTagName("returnprice")->item(0)->nodeValue;
$xmlval['originalprice'] = $xml->getElementsByTagName("originalprice")->item(0)->nodeValue;

这样的事情应该做你想要的。遍历productname，quantity等值的列表，依次将它们添加到items数组中：

$xmlval['items'] = array();
$productname = $xml->getElementsByTagName("productname");
$quantity = $xml->getElementsByTagName("quantity");
$returnprice = $xml->getElementsByTagName("returnprice");
$originalprice = $xml->getElementsByTagName("originalprice");
for ($i = 0; $i < $productname->length; $i++) {
    $xmlval['items'][$i] = array('productname' => $productname->item($i)->nodeValue,
                                 'quantity' => $quantity->item($i)->nodeValue,
                                 'returnprice' => $returnprice->item($i)->nodeValue,
                                 'originalprice' => $originalprice->item($i)->nodeValue);
}
print_r($xmlval['items']);

输出：

Array (
 [0] => Array (
    [productname] => something
    [quantity] => 1
    [returnprice] => $19.95
    [originalprice] => $19.95
  )
  [1] => Array (
    [productname] => something2
    [quantity] => 5
    [returnprice] => $19.95
    [originalprice] => $19.95
  )
  [2] => Array (
    [productname] => something3
    [quantity] => 8
    [returnprice] => $19.95
    [originalprice] => $19.95
  )
)
