我有一个这样的XML文件,我想把question、oid、content都输出,而且输出的格式为:
问题:542
选项:A 内容:1111111
选项:B 内容:2222222
问题:123
选项:C 内容:3333333
选项:D 内容:4444444
应该如何做?
<?xml version="1.0" encoding="utf-8"?><parent> <title>3</title> <author>admin</author> <contentall> <subject> <question>542</question> <option> <oid>A</oid> <content>1111111</content> </option> <option> <oid>B</oid> <content>2222222</content> </option> </subject> <subject> <question>123</question> <option> <oid>C</oid> <content>3333333</content> </option> <option> <oid>D</oid> <content>4444444</content> </option> </subject> </contentall></parent>
$s =<<< XML<?xml version="1.0" encoding="utf-8"?><parent> <title>3</title> <author>admin</author> <contentall> <subject> <question>542</question> <option> <oid>A</oid> <content>1111111</content> </option> <option> <oid>B</oid> <content>2222222</content> </option> </subject> <subject> <question>123</question> <option> <oid>C</oid> <content>3333333</content> </option> <option> <oid>D</oid> <content>4444444</content> </option> </subject> </contentall></parent>XML;$xml = simplexml_load_string($s);foreach($xml->contentall->subject as $item) { echo "问题:$item->question
"; foreach($item->option as $note) echo "选项:$note->oid 内容:$note->content
";}

你把那两个 echo 语句改成向数组赋值就可以了

还有一个问题,如何把我的xml文件和php文件是分开的,那么如何使用simplexml_load_string
simplexml_load_file 就是从文件加载
