通过SimpleXMLElement访问XML加载中的嵌套节点
我有一个具有此结构的XML文件。
<?xml version="1.0" encoding="ISO-8859-1"?>
<COMMUNITIES>
<COMMUNITY ID="c001">
<NAME>Town Services</NAME>
<TOP>50</TOP>
<LEFT>50</LEFT>
<WIDTH>200</WIDTH>
<HEIGHT>300</HEIGHT>
<URLS>
<URL ID="U001">
<NAME>Google.com</NAME>
<URL>http://www.google.com</URL>
</URL>
<URL ID="U002">
<NAME>Bing.com</NAME>
<URL>http://www.bing.com</URL>
</URL>
<URL ID="U003">
<NAME>Yahoo.com</NAME>
<URL>http://www.yahoo.com</URL>
</URL>
<URL ID="U004">
<NAME>Aol.com</NAME>
<URL>http://www.aol.com</URL>
</URL>
</URLS>
</COMMUNITY>
</COMMUNITIES>
我可以通过此脚本通过Height获取一级元素名称。
<?php
function get_nodes() {
// load SimpleXML
$nodes = new SimpleXMLElement('communities.xml', null, true);
foreach($nodes as $node) // loop through
{
echo "<div id = '".$node['ID']."' class= 'comdiv ui-widget-content' style = 'top: ".$node->TOP."px; left: ".$node->LEFT."px; width: ".$node->WIDTH."px; height: ".$node->HEIGHT."px;'>
";
echo " <p class = 'comhdr editableText ui-widget-header'>".$node->NAME."</p>
";
echo " <a href='#' onClick="delete_div('".$node['ID']."');">Delete</a>
";
echo " <a href='#' onClick="add_url('".$node['ID']."');">Add URL</a>
";
echo "</div>
";
echo "<script type='text/javascript'>
";
echo " $('#".$node['ID']."').resizable();
";
echo " $('#".$node['ID']."').draggable();
";
echo " $('#".$node['ID']."').draggable('option', 'handle', '.comhdr');
";
echo "</script>
";
$nodeid = $node['ID'];
$xurls = $node->URL; // WHAT IS THE WAY TO GET TO <URLS> and LOOP THOUGH ALL <URL> NODES
$nurls = sizeof($xurls);
}
echo "<script type='text/javascript'>
";
echo " $('.editableText').editableText();
";
echo "</script>
";
return;
}
echo get_nodes();
?>
如何获取包含在节点中的节点的数组?获得该数组后,我必须检索每个URL的名称和URLC。
谢谢。
解决方案
感谢您的所有建议。它们都为我提供了比以前更多的有关访问嵌套节点的信息。我接受了杰米建议的修改版本。对于每个社区节点,我使用此循环访问URL。
foreach($node->URLS->URL as $url)
{
// Print HTML elements with the URL information
}
以下是完整的工作脚本。
<?php
function get_nodes() {
// load SimpleXML
$nodes = new SimpleXMLElement('communities.xml', null, true);
foreach($nodes as $node) // loop through
{
echo "<div id = '".$node['ID']."' class= 'comdiv ui-widget-content' style = 'top: ".$node->TOP."px; left: ".$node->LEFT."px;
width: ".$node->WIDTH."px; height: ".$node->HEIGHT."px;'>
";
echo " <p class = 'comhdr editableText ui-widget-header'>".$node->NAME."</p>
";
echo " <a href='#' onClick="delete_div('".$node['ID']."');">Delete</a>
";
echo " <a href='#' onClick="add_url('".$node['ID']."');">Add URL</a>
";
echo "</div>
";
echo "<script type='text/javascript'>
";
echo " $('#".$node['ID']."').resizable();
";
echo " $('#".$node['ID']."').draggable();
";
echo " $('#".$node['ID']."').draggable('option', 'handle', '.comhdr');
";
echo "</script>
";
foreach($node->URLS->URL as $url)
{
echo "<script type='text/javascript'> alert('Node: ".$node['ID']." has URLS:".$url['ID']." ".$url->NAME." ".$url->URL." ');
</script>";
}
}
echo "<script type='text/javascript'>
";
echo " $('.editableText').editableText();
";
echo "</script>
";
return;
}
echo get_nodes();
?>
