使用PHP、SimpleXML和Xpath的XML提要和命名空间
使用PHP、SimpleXML和Xpath的XML提要和命名空间
提问于 2015-07-23 12:13:58
嗨，我已经为这个难题挣扎了一段时间了，现在如何从这个嵌入的命名空间中获取数据--这里是xml提要--我已经削减了它，以便更容易阅读。

</feed>我试图访问<crm:reference><crm:name><crm:openedDate>名称空间，但失败了，我看过类似的项目，但我认为它是名称空间中的名称空间，这里是我解析数据的尝试。
<?php
$xml = simplexml_load_file("sage.xml");
$xml->registerXPathNamespace('sdata', 'http://schemas.sage.com/sdata/sync/2008/1');
foreach($xml->xpath("//sdata:payload") as $entry) {
$entry->registerXPathNamespace('sdata', 'http://schemas.sage.com/sdata/sync/2008/1');
$entry->registerXPathNamespace('crm', 'http://schemas.sage.com/crmErp/2008');
$content = $entry->xpath("/sdata:payload/crm:tradingAccount/crm:active");
//$article = feed->xpath("/sdata:payload/crm:tradingAccount/crm:active");
foreach($content as $c) {
// echo $c->reference . " | " . $c->name . "/" . $c->accountOpenedDate . "<br />\n";
}
}
var_dump($content);
var_dump($c);任何关于我的问题的指示都会有帮助

foreach($xml->xpath("//sdata:payload") as $entry) {
// xpath here must be from payload to tradingAccount
$content = $entry->xpath("./crm:tradingAccount");
foreach($content as $c) {
// Make set of children with prefix crm
$nodes = $c->children('crm', true);
echo $nodes->reference . " | " . $nodes->name . " / " . $nodes->openedDate . "<br />\n";
}

它可以很简单，如：
$xml = simplexml_load_file("sage.xml");
$reference = $xml->xpath("//crm:reference");
$name = $xml->xpath("//crm:name");
$openedDate = $xml->xpath("//crm:openedDate");
echo "reference: ". $reference[0] . "<br>";
echo "name: ". $name[0] . "<br>";
echo "openedDate: ". $openedDate[0] . "<br>";如果您想要使用foreach循环来获取“crm”的所有子级，则可以执行以下操作。如果要将子级设置为前缀(true)，则至少需要5.2.0。
$xml = simplexml_load_file("sage.xml");
foreach($xml->xpath("//crm:tradingAccount") as $entry) {
$child = $entry->children('crm', true);
}
echo "reference: ". $child->reference . "<br>";
echo "name: ". $child->name . "<br>";
echo "openedDate: ". $child->openedDate . "<br>";页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
