可用php解析,也可用js解析。php和js直接的区别是,一个是用 . ,一个是 -> ,其他都一样
php中loadXML方法中参数是xml的字符串,load方法中参数是xml文件路径
$dom = new DOMDocument();
$dom->loadXML($xmlstring);
$rootNode = $dom->documentElement;
node属性
nodeType:显示节点的类型
nodeName:显示节点的名称
nodeValue:显示节点的值
attributes:获取一个属性节点
firstChild:表示某一节点的第一个节点
lastChild:表示某一节点的最后一个子节点
childNodes:表示所在节点的所有子节点
parentNode:表示所在节点的父节点
nextSibling:紧挨着当前节点的下一个节点
previousSibling:紧挨着当前节点的上一个节点
node方法
asChildNodes()方法:判定一个节点是否有子节点,有返回true,没有返回false
removeChild()方法:去除一个节点
appendChild()方法:添加一个节点,如果文档树中已经存在该节点,则将它删除,然后在新位置插入
replaceChild()方法:从文档树中删除(并返回)指定的子节点,用另一个节点来替换它
insertBefore()方法:在指定节点的前面插入一个节点,如果已经存在,则删除原来的,然后在新位置插入
cloneNode()方法:复制一个节点,该方法有一个参数,true表示同时复制所有的子节点,false表示近复制当前节点\
下面是js解析Dom
php解析xml:php用DOMDocument解析xml,不能解析含有命名空间的xml,而且对节点的值有点问题,它包含子节点的值
xml:

php代码:
<?php
$myfile = fopen("comp.xml", "r") or die("Unable to open file!");
$xmlstring=fread($myfile,filesize("comp.xml"));
fclose($myfile);
$dom = new DOMDocument();
$dom->loadXML($xmlstring);
$ary = array();
$num = 0;
$flag = "①";
genArray($dom->documentElement, $ary, $num, $flag);
print_r(json_encode($ary));
function genArray($node, &$ary ,&$num, $flag){
$nodeArray = array();
$num = $num + 1;
$numStr = $flag.$num;
if ($node->hasAttributes()) {
foreach ($node->attributes as $attr) {
$nodeArray[$attr->nodeName] = $attr->nodeValue;
}
}
if(isset($node->nodeValue)){
echo "nodepath:".($node->getNodePath())."<br/>";
$nodeArray['textValue'] = trim($node->nodeValue);
}
if ($node->hasChildNodes()) {
if ($node->childNodes->length == 1) {
genArray($node->firstChild, $nodeArray,$num, $flag);
} else {
foreach ($node->childNodes as $childNode) {
if ($childNode->nodeType != XML_TEXT_NODE) {
genArray($childNode, $nodeArray,$num, $flag);
}
}
}
}
$ary[($node->nodeName).$numStr] = $nodeArray;
}
?>
$childNode = $node->getElementsByTag("div").item(0);php和js直接的区别是,js中直接用document相当于php中的$phpDocument
$dom = new DOMDocument();
$dom->loadXML($xmlstring);
$phpDocument = $dom->documentElement;
