使用SimpleXML,可以使用
attributes()
方法访问属性:
<?php
$xml = simplexml_load_file( "Service/Forex_Content.xml" );
foreach( $xml->Exrate[0]->attributes() as $a => $b ) {
echo $a . '="' . $b ."\"\n";
}
试试这个:
function recurseXML($xml, $step)
{
echo "<table cellpadding=\"2\" cellspacing=\"2\" width=\"100%\" border=\"1\">";
$step++;
foreach($xml as $key0 => $value)
{
if($key0=='Exrate')
{
echo "\n<tr>\n";
foreach($value->attributes() as $attributeskey0 => $attributesvalue1)
{
echo " <td> [$attributeskey0] = $attributesvalue1</td>\n";
}
echo "</tr>\n\n";
}
else
{
echo "\n<tr><td colspan=\"5\">$value</td></tr>";
}
}
echo "</table>\n";
}
$xml = simplexml_load_file("http://www.vietcombank.com.vn/ExchangeRates/ExrateXML.aspx");
recurseXML($xml, 0);
用$value->attributes()
替换$value->@attributes
。您可能需要进一步沿着树向下移动才能到达所需的节点,但您可以对任何项目调用attributes()
。函数recurseXML($xml,$step)
{
回声“;
$step++;
foreach($xml作为$key0=>$value)
{
如果($key0=='Exrate')
{
回显“\n\n”;
foreach($value->attributes()作为$attributeskey0=>$attributesvalue1)
{
回显“[$attributeskey0]=$attributesvalue1\n”;
}
回显“\n\n”;
}
其他的
{
回显“\n$value”;
}
}
回音“\n”;
}
$xml=simplexml\u加载文件(“http://www.vietcombank.com.vn/ExchangeRates/ExrateXML.aspx");
recurseXML($xml,0);
试着解释一下代码。初始代码中有什么错误?
foreach ($value->attributes() as $key=>$val){
// do something
}
<?php
$xml = simplexml_load_file( "Service/Forex_Content.xml" );
foreach( $xml->Exrate[0]->attributes() as $a => $b ) {
echo $a . '="' . $b ."\"\n";
}
function recurseXML($xml, $step)
{
echo "<table cellpadding=\"2\" cellspacing=\"2\" width=\"100%\" border=\"1\">";
$step++;
foreach($xml as $key0 => $value)
{
if($key0=='Exrate')
{
echo "\n<tr>\n";
foreach($value->attributes() as $attributeskey0 => $attributesvalue1)
{
echo " <td> [$attributeskey0] = $attributesvalue1</td>\n";
}
echo "</tr>\n\n";
}
else
{
echo "\n<tr><td colspan=\"5\">$value</td></tr>";
}
}
echo "</table>\n";
}
$xml = simplexml_load_file("http://www.vietcombank.com.vn/ExchangeRates/ExrateXML.aspx");
recurseXML($xml, 0);
