我有一个像下面这样的XML结构作为SimpleXMLElement:
<?xml version="1.0" encoding="UTF-8"?>
<phonebooks>
<phonebook name="phonebook">
...
<contact>
<carddav_uid>70ad8a26-21ab-4b42-b641-44a7667e802a</carddav_uid>
<telephony>
<number id="0" type="work">05171290</number>
<number id="1" type="work">05171291919</number>
<number id="2" type="work">05171292000</number>
<number id="3" type="work">05171292010</number>
<number id="4" type="work">05171292245</number>
<number id="5" type="work">05171292313</number>
<number id="6" type="work">05171292383</number>
<number id="7" type="work">05171292617</number>
<number id="8" type="work">05171292761</number>
</telephony>
<person>
<realName>ACME Company</realName>
</person>
</contact>
...
</phonebook>
</phonebooks>
目标是,如果carddav_uid主要和次要的电话号码匹配,则应该为该电话号码添加某些属性。第一个条件是carddav_uid,因为电话号码可能会出现在多个联系人中(例如,具有相同座机号码的不同家庭成员)
找到合适的联系人很容易:
if ($contact = $xmlTargetPhoneBook->xpath(sprintf('//contact[carddav_uid = "%s"]', $uid))) {
我认为使用xpath在节点中搜索正确的电话号码比遍历结构更容易:
if ($contact = $xmlTargetPhoneBook->xpath(sprintf('//contact[carddav_uid = "%s"]', $uid))) {
if ($phone = $contact[0]->xpath(sprintf('/telephony/number[text() = "%s"]', $number))) {
// check for debugging
print_r($phone);
/*
$phone->addAttribute($attribute = $value);
*/
}
}
但我什么也没收到:
Array
(
)
我认为错了吗?
答案 0 :(得分:1)
/telephony/number
从文档的根目录中选择。要从上下文项(contact
元素)中进行选择,请使用./telephony/number
或简单地使用telephony/number
