PHP中使用SimpleXML检查XML文件结构实例
这篇文章主要介绍了PHP中使用SimpleXML检查XML文件结构实例,本文讲解使用SimpleXML来检查一个XML文件是否符合规范的方法,需要的朋友可以参考下
利用 SimpleXML 去检查 XML 结构是否符合规格,为了让这个程序可以多用途,采用了一个基准文件的作为结构准则,依据里面定义的节点跟属性,去检查文件是否符合基本要求的格式。
复制代码 代码如下:
/**检查 XML 文件结构
* @param string $baseFilePath 基准结构文件
* @param string $checkFilePath 待检查文件
* @return bool 当结构与基准文件相符合时则传递 true,否则是 false
* */
function checkXmlFileStructure($baseFilePath,$checkFilePath){
/*开启 Base File*/
if(!file_exists($baseFilePath)){ return false; }
$base = simplexml_load_file($baseFilePath);
if($base===false){ return false; }
/*开启 Check File*/
if(!file_exists($checkFilePath)){ return false; }
$check = simplexml_load_file($checkFilePath);
if($check===false){ return false; }
/*比较起始点的名称*/
if($base->getName() != $check->getName()){ return false; }
/*比较结构*/
return checkXmlStructure($base,$check);
}
/**检查 XML 结构
* @param SimpleXMLElement $base 基准结构对象
* @param SimpleXMLElement $check 待检查 XML 对象
* @return bool 当结构与基准对象相符合时则传递 true,否则是 false
* */
function checkXmlStructure($base,$check){
/*检查属性*/
foreach ($base->attributes() as $name => $baseAttr){
/*必要的属性不存在*/
if(!isset($check->attributes()->$name)){ return false; }
}
/*当没有子节点时,则检查对象也不能有子节点*/
if(count($base->children())==0){
return (count($check->children())==0);
}
/*将检查对象的子节点分群*/
$checkChilds = array();
foreach($check->children() as $name => $child){
$checkChilds[$name][] = $child;
}
/*检查子节点*/
$checked = array();
foreach($base->children() as $name => $baseChild){
/*跳过已经检查的子节点*/
if(in_array($name, $checked)){ continue; }
$checked[] = $name;
/*检查必要的子节点是否存在*/
if(emptyempty($checkChilds[$name])){ return false; }
foreach ($checkChilds[$name] as $child){
/*递回检查子节点*/
if( !checkXmlStructure($baseChild, $child) ){ return false; }
}
}
return true;
}
/*==============================================================================*/
if(isset($_SERVER['argv'])){
parse_str(preg_replace('/&[\-]+/','&',join('&',$_SERVER['argv'])), $_GET);
if(emptyempty($_GET['base_file']) || emptyempty($_GET['check_file'])){
echo "Run: ".basename(__FILE__)." base_file=base.xml check_file=check.xml\n"; exit(1);
}
exit( checkXmlFileStructure($_GET['base_file'],$_GET['check_file']) ? 0 : 1);
}else{
if(emptyempty($_GET['base_file']) || emptyempty($_GET['check_file'])){
echo "Run: ".basename(__FILE__)."?base_file=base.xml&check_file=check.xml
"; exit;
}
echo( checkXmlFileStructure($_GET['base_file'],$_GET['check_file']) ? '1' : '0');
}
使用方式(shell)
