我想编写一个函数,将(理论上)未知的XML数据结构解析为等效的PHP数组。
以下是我的示例XML:
<?xml version="1.0" encoding="UTF-8"?>
<content>
<title>Sample Text</title>
<introduction>
<paragraph>This is some rudimentary text</paragraph>
</introduction>
<description>
<paragraph>Here is some more text</paragraph>
<paragraph>Even MORE text</paragraph>
<sub_section>
<sub_para>This is a smaller, sub paragraph</sub_para>
<sub_para>This is another smaller, sub paragraph</sub_para>
</sub_section>
</description>
</content>
我从devarticles修改了这个DOM迭代函数:
$data = 'path/to/xmldoc.xml';
$xmlDoc = new DOMDocument(); #create a DOM element
$xmlDoc->load( $data ); #load data into the element
$xmlRoot = $xmlDoc->firstChild; #establish root
function xml2array($node)
{
if ($node->hasChildNodes())
{
$subNodes = $node->childNodes;
foreach ($subNodes as $subNode)
{
#filter node types
if (($subNode->nodeType != 3) || (($subNode->nodeType == 3)))
{
$arraydata[$subNode->nodeName]=$subNode->nodeValue;
}
xml2array($subNode);
}
}
return $arraydata;
}
//The getNodesInfo function call
$xmlarray = xml2array($xmlRoot);
// print the output - with a little bit of formatting for ease of use...
foreach($xmlarray as $xkey)
{
echo"$xkey<br/><br/>";
}
现在,由于我将元素传递给数组的方式,我正在覆盖共享节点名称的所有元素(因为我理想地希望为这些键提供与其原始节点相同的名称)。我的递归并不好...但是,即使我清空括号 - 第二层节点仍然作为第一层的值进入(参见描述节点的文本)。
任何人都有任何想法如何更好地构建它?

你可能最好只是从网上抓取一些代码
http://www.bin-co.com/php/scripts/xml2array/
/**
* xml2array() will convert the given XML text to an array in the XML structure.
* Link: http://www.bin-co.com/php/scripts/xml2array/
* Arguments : $contents - The XML text
* $get_attributes - 1 or 0. If this is 1 the function will get the attributes as well as the tag values - this results in a different array structure in the return value.
* $priority - Can be 'tag' or 'attribute'. This will change the way the resulting array sturcture. For 'tag', the tags are given more importance.
* Return: The parsed XML in an array form. Use print_r() to see the resulting array structure.
* Examples: $array = xml2array(file_get_contents('feed.xml'));
* $array = xml2array(file_get_contents('feed.xml', 1, 'attribute'));
*/
function xml2array($contents, $get_attributes=1, $priority = 'tag') {

您可能对SimpleXML或xml_parse_into_struct感兴趣。
$ arraydata既没有传递给后续调用xml2array(),也没有使用返回值,所以是“我的递归不是很好......”是真的;-)
要将新元素附加到现有数组,可以使用空方括号$ arr [] = 123; $ arr [$ x] [] = 123;
