感谢您提供所有帮助...我知道我需要根据代码创建一个变量。我想我可以使用XPath，但我不知道该怎么做。谢谢

Answer 1

使用XPath。您可以指定...

//Account[Groups/Group/GroupName="Company 3"]/AccountNumber

这表示要查找一个具有GroupName和所需值的AccountNumber元素。

使用[]可以给您一个条件，以选择之后的元素，但是result元素是[之前的元素。因此，其结果将是Account元素，然后最后的/AccountNumber说在Account元素中选择AccountNumber元素。这给...

<AccountNumber>45166</AccountNumber>

Answer 2

PHP的DOM扩展提供了一个DOMXpath类。借助其DOMXpath::evaluate()，您可以获取节点和值。

$document = new DOMDocument();
$document->loadXML($xml);
$xpath = new DOMXpath($document);

var_dump($xpath->evaluate('string(//Account[Groups/Group/GroupName="Company 3"]/AccountNumber)'));

输出：

string(5) "45166"

Xpath表达式

文档中的任何Account元素节点...
//Account
...具有值为Groups/Group/GroupName的{{1}} ...
Company 3
...其//Account[Groups/Group/GroupName="Company 3"]子元素节点...
AccountNumber
...作为字符串：
//Account[Groups/Group/GroupName="Company 3"]/AccountNumber

string(//Account[Groups/Group/GroupName="Company 3"]/AccountNumber)将返回列表中第一个节点的文本内容，如果找不到节点，则返回一个空字符串。

Answer 3

这是我最终想出的：

$GroupName = "Company 3";

$xmlstr = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<GetAccountsWithAccessResponse>
    <Result>Success</Result>
    <Accounts>
        <Account>
            <AccountNumber>23871</AccountNumber>
            <Contact_id>10135</Contact_id>
            <IsOwner>N</IsOwner>
            <Groups>
                <Group>
                    <GroupID>12</GroupID>
                    <GroupName>Company 1</GroupName>
                    <GroupType>Private</GroupType>
                    <IncludeLoginLink>Yes</IncludeLoginLink>
                </Group>
                <Group>
                    <GroupID>28</GroupID>
                    <GroupName>Partners Group</GroupName>

        </Account>
    </Accounts>
</GetAccountsWithAccessResponse>
XML;

$xmlstring = new SimpleXMLElement($xmlstr);

//This Works for the GroupID:
$IDS = $xmlstring->xpath('//Group[GroupName="' . $GroupName . '"]/GroupID');
foreach($IDS as $theID) {
    $GroupID = $theID;
}

echo "The Group ID is $GroupID \n\n";

//This works for the Account Number
$acctnumbers = $xmlstring->xpath('//Account[Groups/Group/GroupName="' . $GroupName . '"]/AccountNumber');
    /* The following xpath also works:  $acctnumbers = $xmlstring->xpath('//Group[GroupName="' . $GroupName . '"]/parent::Groups/parent::Account/AccountNumber');  */

foreach($acctnumbers as $number) {
    $AccountNumber = $number;
}

echo "The account number is $AccountNumber";
