我需要输出

[[100510，LOCAL CARD，UNITED KINGDOM，GB，GBR，826，NULL，NULL，NULL， NULL]，[100515，LOCAL CARD，NORWAY，NO，NOR，578，NULL，NULL，NULL， NULL]，[103753，LOCAL CARD，I＆amp; M BANK，DEBIT，PREPAID，KENYA，KE，KEN， 404，NULL，NULL]，[104001，LOCAL CARD，LUXURY JEWELLERY CLASS（LJC） - TDFS，CANADA，CA，CAN，124]]

但是，我无法得到这个。请提供解决方案。我必须使用Xpath来获得此输出。

Answer 1

看起来您希望第二个XPath与第一个XPath返回的// Any tablet device. if( $detect->isTablet()) { } // Exclude tablets. if( $detect->isMobile() && !$detect->isTablet()) { } // Check for a specific platform with the help of the magic methods: if( $detect->isiOS()) { } if( $detect->isAndroidOS()) { } if( $detect->isWindowsPhoneOS()) { }相关。此外，对于每个$detect = new Mobile_Detect; if($detect->isMobile() || $detect->isTablet()) { echo "<link rel='stylesheet' href='mobile.css type='text/css' />"; } else { echo "<link rel='stylesheet' href='style.css type='text/css' />"; }，您需要一个不同的bin实例，因此需要在外部循环的范围内声明ArrayList。我不是Java开发人员，但我认为它应该是这样的：

bin

使用XPath解析XML并将所需字段添加到列表中
