【问题描述】：
如果该节点的内容与另一个节点（兄弟）匹配，我正在尝试显示该节点的文本内容。这是 XML：

我成功地显示了每个 ChitCode 和 ChitDate，因为它们位于 Line[@number] 节点中。我想显示包含文本“Chit#: XXXXXX”的 Body 节点，其中 xxxxxx 匹配 Line->ChitCode。这是我的 php，它显示了正文，但它显示了所有行项目的第一个正文：
<?php
foreach($Chitquery as $Chit)
{
foreach($Linequery as $Line)
{
echo "<label class='collapse' for='".$Line->ChitCode."-".$Line->ChitDate."'>".$Line->Description."</label>
<input id='".$Line->ChitCode."-".$Line->ChitDate."' type='checkbox'>
<div>";
// Creates hide - show link for each Description item
// Start getting the matching Chit Code from Chit/Body
if ($Chit->Code = $Line->ChitCode)
{
echo $Chit->Body."</div>";
}
else
{
echo " ".$Line->ChitCode."</div>";
} // End If
} //End foreach Linequery
} // End foreach Chitquery
?>
这是回声 $Chit->Body。"";我需要帮助，我想显示包含 $Line->ChitCode 值的 Body。
哦，是的，由于“foreach”语句的放置不当，这些行重复得很奇怪！ 帮助！提前致谢！
更新：我已经更改了我的 php 代码，现在我可以使用隐藏显示 div，没有重复，但我得到的是 'array' 而不是 $ChitBody。我无法弄清楚如何在 $ChitBody = $member->xpath('Chits/Chit/Body[text()="'.$Line->ChitCode.'" 中找到包含 $Line->ChitCode 的 Body 节点] ');
<?php
foreach($Linequery as $Line) {
$ChitCode = $member->Chits->Chit->Code;
$ChitBody = $member->xpath('Chits/Chit/Body[text()="'.$Line->ChitCode.'"] ');
echo "<label class='collapse' for='".$Line->ChitCode."-".$Line->ChitDate."'>".$Line->Description."</label>
<input id='".$Line->ChitCode."-".$Line->ChitDate."' type='checkbox'>"; // Creates hide - show link for each Description item
// Start getting the matching Chit Code from Chit/Body
if ($ChitCode = $Line->ChitCode) {
echo "<div>Code: ".$ChitCode."<br>".$ChitBody."</div>";
} else {
echo "<div>".$Line->ChitCode."</div>";
} // End If
} //End foreachLinequery
?>
【问题讨论】：
-
if 语句中有 $Chit->Code = $Line->ChitCode。尝试将其更改为 $Chit->Code == $Line->ChitCode.
