Question

我有两个不同的xml doxument，我从webservice获得。

通过提交第一个请求，我将获得包含酒店基本信息并具有此类结构的xml

<offers>
<offer>
    <city_id>5</city_id>
    <city>Barcelona</city>
    <name>EnGrande test hotel</name>
    <address>Calle Muntaner 262</address>
    <price_no_vat>80</price_no_vat>
    <currency>EUR</currency>
    <type>Hotel</type>
    <description>

    <offer_url>http://www.somesite.com/eg_offer_detail.php?hotel_id=191&checkin=2009-05-01&checkout=2009-05-02&city_id=5&guests=2</offer_url>
    <distance>3.175</distance>
</offer>

和第二个xml文档，其中包含酒店的详细信息并具有此类结构

<hotels>
<hotel> 
    <hotel_id>191</hotel_id> 
    <name>Test hotel</name> 
    <type>hostel</type> 
    <category>2</category>

        <amenity>Hair dryer</amenity>
        <amenity>Towels & sheets</amenity>
    </amenities>
</hotel>

现在第二个xml文档包含同一城市的许多酒店。我想在第二个xml文档中搜索酒店名称并显示其详细信息。我为此创建了一个php代码，看起来像这样

<?php 
$city_id = 6;

$request =  "http://www.somewebsite.com/feeds/phpfile.php?vendor_key=xxx&checkin=26-11-2012&checkout=30-11-2012&guests=3&city_id=".$city_id;

$same_city_hotels_request = "http://www.somewebsite.com/feeds/get-hotels.php?vendor_key=xxx&city_id=".$city_id; 


$offerxml = simplexml_load_file($request);
$same_city = simplexml_load_file($same_city_hotels_request);

$hotel = $offerxml->offer;

for($i=0;$i<=10;$i++){   

$hotel_info = $same_city->xpath("//hotel/name[contains(text(),'".$hotel[$i]->name."')]");

{
?>

<tr><td>name</td><td>category</td><td>city</td><td>Address</td><td>price</td><td>Image</td></tr>
<tr><td> <?php echo $hotel[$i]->name; ?></td>
<td><?php echo $hotel_info[$i]->category; ?></td>
<td> <?php echo $hotel[$i]->city; ?> </td>
<td><?php echo $hotel[$i]->address; ?></td><td><?php echo $hotel[$i]->price; ?></td>
<td><?php echo $hotel_info[$i]->image; ?></td></tr>

<?php } ?>

任何人都可以告诉我这里我做错了什么吗？

Answer 1

您的XPath返回name元素：

$hotel_info = $same_city->xpath(
    "//hotel/name[contains(text(),'".$hotel[$i]->name."')]"
);

但是，您的PHP代码会尝试使用该元素，就像它是hotel元素一样。

使XPath返回hotel元素，而不是name元素。以下任何一种形式都应该这样做。

"//hotel/name[contains(text(),'".$hotel[$i]->name."')]/parent::*"
"//hotel[name[contains(.," . $hotel[$i]->name . ")]]"
"//hotel[contains(string(name)," . $hotel[$i]->name . ")]"

用php中的xpath搜索特定节点的兄弟？
