用php将XML数据插入mysql

代表问题的xml文件部分(xml文件有数百个客户记录)

    <?xml version="1.0" encoding="utf-8"?>
    <test>
       <customer>   
          <name>customer 1</name>
          <address>address 1</address>
          <city>city 1</city>
          <state>state 1</state>
          <zip>zip 1</zip>
          <phone>phone 1</phone>
          <buyerinfo>
             <shippingaddress>
               <name>ship to</name>
               <address>Ship address1</address>
             </shippingaddress>
           </buyerinfo>
           <shippingDetail>
             <saletax>
               <saletaxamount>2</saletaxamount>
             </saletax>
           </shippingDetail>
       </customer>...

下面是我的代码

 //Xml string is parsed and creates a DOM Document object
    $responseDoc = new DomDocument();        
    $responseDoc->load('test.xml');     
    foreach ($responseDoc->getElementsByTagName('customer') as $customer){

     $sSQL = sprintf(
    "INSERT INTO customer (name, address, city, state, zip, phone, shipto, shipadderss, tax) 
    VALUES ('%s','%s', '%s', '%s','%s','%s', '%s','%s','%s')",
    mysql_real_escape_string($customer->getElementsByTagName('name')->item(0)->nodeValue),
    mysql_real_escape_string($customer->getElementsByTagName('address')->item(0)->nodeValue),
    mysql_real_escape_string($customer->getElementsByTagName('city')->item(0)->nodeValue),
    mysql_real_escape_string($customer->getElementsByTagName('state')->item(0)->nodeValue),
    mysql_real_escape_string($customer->getElementsByTagName('zip')->item(0)->nodeValue),
    mysql_real_escape_string($customer->getElementsByTagName('phone')->item(0)->nodeValue)
    ?
    ?
    ?       
);
$rResult = mysql_query($sSQL);

if(mysql_errno() > 0)
{
    printf(
        '<h4 style="color: red;">Query Error:</h4>
        <p>(%s) - %s</p>
        <p>Query: %s</p>
        <hr />',
        mysql_errno(),
        mysql_error(),
        $sSQL
    );
}

    }

问题：

>我如何使用以下方法获取customer.buyerinfo.shippingaddress.name节点值
我的插入语句中的mysql_real_escape_string？用“ ???”表示

我有两个节点具有相同节点名称“名称”的事实,一个
是customer.name,另一个是
customer.buyerinfo.shippingaddress.name命名会引起问题
使用getElementsByTagName“ name”标签获取值.
>与第一个相同,但是如何获取saletaxamount节点数据值？

请帮助.谢谢！

解决方法:

对于您拥有的XML数据,我希望使用SimpleXML扩展,它附带了您所需的所有内容,并且编写的代码并不多(这是DOMDocument的妹妹).

因此,对于输入数据中的每个客户,您都希望获取9个左右的值.您可以将这些值公式化为xpath：

$values = <<<XPATH
(
    name
    |address
    |city
    |state
    |zip
    |phone
    |buyerinfo/shippingaddress/name
    |buyerinfo/shippingaddress/address
    |shippingDetail/saletax/saletaxamount
)
XPATH;

这与数据库查询类似.您创建了一个包含查询的字符串,用于Xpath语言中的XML.

我们对SQL进行了相同的操作,因为两者应该并存,所以这是相应的SQL模式：

$pattern = <<<SQL
INSERT INTO customer
  (
    name, address, city, state, zip, phone, shipto, shipadderss, tax
  )
  VALUES
  (
    '%s','%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s'
  )
SQL;

现在所有这些需要是打开XML并指定要处理的客户元素：

$customers = simplexml_load_string($test)->customer; // "test.xml"

然后,您只需要遍历每个客户,获取值,对其进行转义,将其插入查询中并运行SQL查询(或创建一个包含多个记录的较大查询)：

foreach ($customers as $customer) 
{
    $data = $customer->xpath($values);
    $escaped = array_map('mysql_real_escape_string', $data);
    $query = vsprintf($pattern, $escaped);

    // you can now run the query now
    // ...
}

是的,那已经是您的代码了.如您所见,利用数组,xpath和SQL,可以大大简化此过程.

对于您的sample-XML中的第一个客户,这将生成以下查询：

INSERT INTO customer
  (
    name, address, city, state, zip, phone, shipto, shipadderss, tax
  )
  VALUES
  (
    'customer 1','address 1', 'city 1', 'state 1', 'zip 1', 'phone 1', 'ship to', 'Ship address1', '2'
  )

整个代码示例：

$values = <<<XPATH
(
    name
    |address
    |city
    |state
    |zip
    |phone
    |buyerinfo/shippingaddress/name
    |buyerinfo/shippingaddress/address
    |shippingDetail/saletax/saletaxamount
)
XPATH;

$pattern = <<<SQL
INSERT INTO customer
  (
    name, address, city, state, zip, phone, shipto, shipadderss, tax
  )
  VALUES
  (
    '%s','%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s'
  )
SQL;

$customers = simplexml_load_string($test)->customer; // "test.xml"

foreach ($customers as $customer)
{
    $data = $customer->xpath($values);
    $escaped = array_map('mysql_real_escape_string', $data);
    $query = vsprintf($pattern, $escaped);

    // you can now run the query now
    $result = mysql_query($query);
    if(mysql_errno())
    {
        printf(
            '<h4 style="color: red;">Query Error:</h4>
            <p>(%s) - %s</p>
            <p>Query:
              <pre>%s</pre>
            </p>
            <hr />',
            mysql_errno(),
            htmlspecialchars(mysql_error()),
            htmlspecialchars($query)
        );
    }
}
