alt php,我怎样才能在PHP中获取a p标签的alt属性？

我正在编写一个只回应价格的脚本.

如果我做：

$alttag = $oNode['p'];

echo $alttag;

php获取当前时间戳、它将回显< p>< / p>中的所有内容.

所以它会回应：

cafénevrij的roodmerk

500克

2 pakken

php修改文件内容、prijs每公斤1,99

199

从网站上,所以你可以看到它的回声199,这是价格,但首先我只需要在< p>< / p>中的199而且我要 .或者,在199之间,因此它将显示1,99或1.99.

如果我做：

$alttag = $oNode['p sup'];

php获取表单数据。echo $alttag;

它只会回复< sup>< / sup>中的99.

如果我做：

$alttag = $oNode['p sup'];

$maintag = $oNode['p']->attr('alt');

php获取网页源码？echo $maintag . $alttag;

嗯……这没什么

我怎么才能得到1和99并且放置一个.或者,它之间看起来像1,99或1.99？

php如何获取时间，完整代码：不包含php函数和数据库连接.

// Extracts offers from html and return in array

function extractSparOffers($url)

{

loadPqUrl($url);

php转义字符怎么使用。//Test $dates = extractDateRange(pq('.contentdatagrid td:first'));

$oNodes = pq('.item');

if($oNodes->count() == 0) throw new Exception('No offers were found.');

foreach($oNodes as $oNode) {

$oNode = pq($oNode);

php的标记、//Test $titleDescCell = $oNode['input#a']->parent();

//Test $titleDescCell['img, input']->remove();

$priceCell = $oNode['span.price1']->parent()->parent();

// Get title and description

$data['title'] = $oNode['.item-content h3'];

php获取当前网址。$data['description'] = $oNode['.item-content p'];

// Get prices (page may contain price ranges)

$alttag = $oNode['p sup'];

$maintag = $oNode['p']->attr('alt');

echo $maintag;

php获取文件列表。//echo $alttag;

//$alttags=preg_match_all('/]*alt="([^"]*)"/i', $html, $matches);

$none = "0.00";

$data['priceBefore'] = $none;

$data['priceAfter'] = $alttag;

// $oNode['item-prijs p.sup.cufon cufon-canvas']->attr('alt') ;

php标识符，// Get image

$imgNode = $oNode['img:only-child'];

if(count($imgNode) > 0)

$img = getimg('http://www.spar.nl/' . $oNode['img:only-child']->

attr('src'));

else $img = '';

$data['image'] = $img;

//Test $data['dateStart'] = $dates['start'];

//Test $data['dateEnd'] = $dates['end'];

$date =date('Y-m-d');

$data['dateStart'] = date('Y-m-d', strtotime("yesterday"));

$data['dateEnd'] = date('Y-m-d', strtotime("tomorrow"));

$data = formatOfferStrings($data);

$odTotal[] = $data;

}

return $odTotal;

}

spiderInit();

$offerData = extractSparOffers('http://www.spar.nl/aanbiedingen/');

//Test processNewOffers('Spar', $offerData, $offerData[0]['dateStart']);

processNewOffers('Spar', $offerData, $dates['start']);
