使用 PHP 将 XML 解析为嵌套列表
我有一个 XML 文件,其中包含嵌套结构中的家谱数据,我想将其解析为嵌套列表。
我有以下代码
<?php
$doc = new DOMDocument();
$doc->load('armstrong.xml');
echo $doc->saveXML();
?>
,它加载到以下 XML 文件中并按原样打印它,
<?xml version="1.0" encoding="UTF-8"?>
<indi>
<id>id1</id>
<fn>Matt</fn>
<bday>1919</bday>
<dday>2000</dday>
<spouse>Evelyn Ross</spouse>
<family>
<indi>
<id>id2</id>
<fn>Jane</fn>
<bday></bday>
<dday></dday>
<spouse></spouse>
<family>
</family>
</indi>
<indi>
<id>id3</id>
<fn>Jason</fn>
<bday></bday>
<dday></dday>
<spouse></spouse>
<family>
</family>
</indi>
<indi>
<id>id4</id>
<fn>Samuel</fn>
<bday></bday>
<dday></dday>
<spouse></spouse>
<family>
<indi>
<id>id5</id>
<fn>John</fn>
<bday></bday>
<dday></dday>
<spouse></spouse>
<family>
</family>
</indi>
<indi>
<id>id6</id>
<fn>John</fn>
<bday></bday>
<dday></dday>
<spouse></spouse>
<family>
</family>
</indi>
</family>
</indi>
</family>
但是我想将其解析为以下格式:
<ul>
<li>
<span class="vcard person" id="id1">
<span class="edit fn">Matt</span>
<span class="edit bday">1956</span>
<span class="edit dday"></span>
<span class="edit spouse">Eunace Fulton</span>
</span>
<ul> ... List of Family ... </ul>
</li>
</ul>
我对 php 很陌生,所以如果这是一个非常简单的问题,我表示歉意!非常感谢任何想法。
编辑
我现在正在使用以下递归循环,但仍然遇到问题
$doc = new DOMDocument();
$doc->load('armstrong.xml');
function outputIndi($indi) {
$i = new DOMDocument();
$i = $indi;
echo '<li>';
echo '<span class="edit fn">' . $indi->getElementsByTagName("fn") . '</span>'; // name not a real attribute, must access through DOM
echo '<span class="edit bday">' . $indi->getElementsByTagName("bday") . '</span>'; // ditto
// ...
echo '<ul>';
foreach ($indi->getElementsByTagName("family") as $subIndi) { // again, family not a real attribute
outputIndi($subIndi);
}
echo '</ul>';
echo '</li>';
}
outputIndi($doc->documentRoot);
?>
I have an XML file which contains family tree data in a nested structure, and I'm wanting to parse it into a nested list.
I have the following code
<?php
$doc = new DOMDocument();
$doc->load('armstrong.xml');
echo $doc->saveXML();
?>
Which loads in the following XML file and prints it as-is
<?xml version="1.0" encoding="UTF-8"?>
<indi>
<id>id1</id>
<fn>Matt</fn>
<bday>1919</bday>
<dday>2000</dday>
<spouse>Evelyn Ross</spouse>
<family>
<indi>
<id>id2</id>
<fn>Jane</fn>
<bday></bday>
<dday></dday>
<spouse></spouse>
<family>
</family>
</indi>
<indi>
<id>id3</id>
<fn>Jason</fn>
<bday></bday>
<dday></dday>
<spouse></spouse>
<family>
</family>
</indi>
<indi>
<id>id4</id>
<fn>Samuel</fn>
<bday></bday>
<dday></dday>
<spouse></spouse>
<family>
<indi>
<id>id5</id>
<fn>John</fn>
<bday></bday>
<dday></dday>
<spouse></spouse>
<family>
</family>
</indi>
<indi>
<id>id6</id>
<fn>John</fn>
<bday></bday>
<dday></dday>
<spouse></spouse>
<family>
</family>
</indi>
</family>
</indi>
</family>
However I want to parse it into the following format:
<ul>
<li>
<span class="vcard person" id="id1">
<span class="edit fn">Matt</span>
<span class="edit bday">1956</span>
<span class="edit dday"></span>
<span class="edit spouse">Eunace Fulton</span>
</span>
<ul> ... List of Family ... </ul>
</li>
</ul>
I'm pretty new to php, so if this is an incredibly simple problem I apologise! Would really appreciate any ideas.
EDIT
I'm now using the following recursive loop but still having problems
$doc = new DOMDocument();
$doc->load('armstrong.xml');
function outputIndi($indi) {
$i = new DOMDocument();
$i = $indi;
echo '<li>';
echo '<span class="edit fn">' . $indi->getElementsByTagName("fn") . '</span>'; // name not a real attribute, must access through DOM
echo '<span class="edit bday">' . $indi->getElementsByTagName("bday") . '</span>'; // ditto
// ...
echo '<ul>';
foreach ($indi->getElementsByTagName("family") as $subIndi) { // again, family not a real attribute
outputIndi($subIndi);
}
echo '</ul>';
echo '</li>';
}
outputIndi($doc->documentRoot);
?>

这是你的代码。您需要添加其余属性(dday,配偶)
RECURSION!
您会看到,它输出有关“indi”的所有信息,循环遍历
的每个孩子。
,并以此为基础进行调用。这有道理吗?Here's your code. You'll need to add the rest of the attributes (dday, spouse)
RECURSION!
You see, it outputs all information about an "indi", loops through each child of
<family>
, and calls itself on that. Does that make sense?
