，我使用的代码搜索每一个绑定元素，然后做的东西与它这样的

foreach($xml->Items->Item->AlternateVersions->AlternateVersion->Binding as $BookBinding) { //loop through the xml data to find the correct ASIN for the kindle edition 
    foreach ($xml->Items->Item->AlternateVersions->AlternateVersion->ASIN as $Kindlestring) 
    { 
     var_dump ($BookBinding); 
     if (preg_match('/Kindle Edition/i',$BookBinding)) 
     { 
      //do stuff 
     } 
    } 
}

但只获得第一次迭代$ Binding和$ ASIN而不是所有4个元素 var_dump的输出是“Unknown Binding”& B0058O8V9U

这不是一个*，而是*，这是正确的。与xpath查询不同，您在这里使用的迭代器每个“仅包含”一个元素。您可能希望使用xpath查询liek'/ */*/Item/*/AlternateVersion/Binding'等代替。 – hakre 2013-05-04 19:40:40

看起来你有一些无效的XML。尝试通过http://www.w3schools.com/xml/xml_validator.asp运行它并在再次尝试之前更正相关错误。 – 2013-05-04 19:34:20

使用''ASIN [follow-sibling :: Binding =“Kindle Edition”]' – Gordon 2013-05-04 20:10:13

这可以帮助你

foreach($xml->Items->Item as $item){ 
    foreach($item->AlternateVersions->AlternateVersion as $alt_version){ 
     var_dump($alt_version->Binding); 
     var_dump($alt_version->ASIN); 
     ... 
    } 
}

首先迭代throught '项目'，然后 'AlternateVersion'。
