我已经搜索了几个小时的 StackOverflow 试图找到可以帮助我的东西，有很多关于子节点的东西，但没有关于 XML 文件中的 Line NUMBERS 并将它们拉入 php 文件的内容。我有一个结构如下的 XML 文件：

<MemberId ID="FC0491">

        <ChitDate>20140331</ChitDate>
      </Line>
    </Details>
  </BillingInfo>
</MemberId>

我雇了人将所有 Line NUMBER 项拉入 PHP 页面，但我只拉入第一个行项。代码如下：

$source = file_get_contents($fname);
$xml = new SimpleXMLElement($source);

foreach($xml->Billing->MemberId as $member){
if($member['ID'] == $uname){
    $balance = $member->BillingInfo->BalanceDue;
    $BalanceForward = $member->BillingInfo->BalanceForward;
    $Payments = $member->BillingInfo->Payments;
    $minimum_cyclyto = $member->BillingInfo->Minimum->CycleTo;
    $minimum_unspent = $member->BillingInfo->Minimum->Unspent;
    $minimum_totalamount = $member->BillingInfo->Minimum->TotalAmount;

    $agin='';
    foreach($member->BillingInfo->Aging->Amount as $a => $b) 
    {
    $agin .=$b.",";
    }
    // Format Date from XML
    $xmlstatedate = $member->BillingInfo->StatementEndDate;
    $statedate = DateTime::createFromFormat("Ymd", $xmlstatedate);
    $statemonth=DateTime::createFromFormat("m Y", $xmlstatedate);
    // Format Date from XML 
    $xmlpaydate = $member->BillingInfo->Details->Line->ChargeDate;
    $paydate = DateTime::createFromFormat("Ymd", $xmlpaydate);
    $TrackingNumber = $member->BillingInfo->Details->Line->TrackingNumber;
    $Description = $member->BillingInfo->Details->Line->Description;
    $SalesAmount = $member->BillingInfo->Details->Line->SalesAmount;
    $charge = $member->BillingInfo->Details->Line->Total;
    $grat = $member->BillingInfo->Details->Line->GST;
    $svc = $member->BillingInfo->Details->Line->PST;
    $tax = $member->BillingInfo->Details->Line->Othertaxes;
}
}   ?>

这是拉入数据的表格；

<table width="100%" border="0" cellpadding="2" cellspacing="2" bordercolor="#FFFFFF">
          <tr> 
            <td width="10%" bgcolor="#CCCCCC"><font size="2" face="Arial, Helvetica, sans-serif"><strong>Date</strong></font></td>

            <td>&nbsp;</td>
          </tr>
        </table>

我想对其进行结构化，以便从行号中提取所有子节点（如果存在）。然后我希望该表为找到的每个 Line NUMBER 生成 ROWS 并显示相关数据。有人可以帮忙吗？

【问题讨论】：

"此函数提供在 xml 标记中定义的属性和值。" php.net/manual/en/simplexmlelement.attributes.php
Xpath: //line[@NUMBER]
知道了。我正在尝试这个： $Linequery = $member->xpath('BillingInfo/Details/Line[@NUMBER => 0] ');
我能够使用 xpath 获取所有数据，然后使用 foreach($Linequery as $Line) { echo $Line->whatever;

标签： php xml nodes

【解决方案1】：

感谢 Marc B，我使用 Xpath 获取所有数据：

$Linequery = $member->xpath('BillingInfo/Details/Line[@NUMBER] ');

然后我替换了旧的 php 语句，例如：

<?php echo $tax; ?>

与

<?php foreach($Linequery as $Line) { echo $Line->Othertaxes; echo "<br>"; } ?>

似乎完全符合我的要求。感谢您为我指明正确的方向！
