我的工作中，我拉对NHL的各种统计数据的项目，并将其插入到SQL表。 目前，我正在刮阶段，并且已经发现，我实现了一个XML解析器，但我不能为我的生活弄清楚如何从中提取信息。 该表可以在这里找到- > http://www.tsn.ca/datafiles/XML/NHL/standings.xml 。 解析器理应产生多dimmensional数组，我只是试图把所有的统计信息从“信息队”一节，但我不知道如何把从阵列中的信息。 我怎么会去拉胜蒙特利尔有多少？ （仅作为对统计数据的其他例子）这就是当前页面看起来像- > http://mattegener.me/school/standings.php下面的代码：
<?php
$strYourXML = "http://www.tsn.ca/datafiles/XML/NHL/standings.xml";
$fh = fopen($strYourXML, 'r');
$dummy = fgets($fh);
$contents = '';
while ($line = fgets($fh)) $contents.=$line;
fclose($fh);
$objXML = new xml2Array();
$arrOutput = $objXML->parse($contents);
print_r($arrOutput[0]); //This print outs the array.
class xml2Array {
var $arrOutput = array();
var $resParser;
var $strXmlData;
function parse($strInputXML) {
$this->resParser = xml_parser_create ();
xml_set_object($this->resParser,$this);
xml_set_element_handler($this->resParser, "tagOpen", "tagClosed");
xml_set_character_data_handler($this->resParser, "tagData");
$this->strXmlData = xml_parse($this->resParser,$strInputXML );
if(!$this->strXmlData) {
die(sprintf("XML error: %s at line %d",
xml_error_string(xml_get_error_code($this->resParser)),
xml_get_current_line_number($this->resParser)));
}
xml_parser_free($this->resParser);
return $this->arrOutput;
}
function tagOpen($parser, $name, $attrs) {
$tag=array("name"=>$name,"attrs"=>$attrs);
array_push($this->arrOutput,$tag);
}
function tagData($parser, $tagData) {
if(trim($tagData)) {
if(isset($this->arrOutput[count($this->arrOutput)-1]['tagData'])) {
$this->arrOutput[count($this->arrOutput)-1]['tagData'] .= $tagData;
}
else {
$this->arrOutput[count($this->arrOutput)-1]['tagData'] = $tagData;
}
}
}
function tagClosed($parser, $name) {
$this->arrOutput[count($this->arrOutput)-2]['children'][] = $this->arrOutput[count($this- >arrOutput)-1];
array_pop($this->arrOutput);
}
}
?>
添加此搜索功能，你的类以及与此代码玩
$objXML = new xml2Array();
$arrOutput = $objXML->parse($contents);
// first param is always 0
// second is 'children' unless you need info like last updated date
// third is which statistics category you want for example
// 6 => the array you want that has wins and losses
print_r($arrOutput[0]['children'][6]);
//using the search function if key NAME is Montreal in the whole array
//result will be montreals array
$search_result = $objXML->search($arrOutput, 'NAME', 'Montreal');
//first param is always 0
//second is key name
echo $search_result[0]['WINS'];
function search($array, $key, $value)
{
$results = array();
if (is_array($array))
{
if (isset($array[$key]) && $array[$key] == $value)
$results[] = $array;
foreach ($array as $subarray)
$results = array_merge($results, $this->search($subarray, $key, $value));
}
return $results;
}
谨防
这个搜索功能是区分大小写的，它需要像匹配修改的百分比在蒙特利尔键或值更改M大写改为小写将是空的
这是我送你的行动使用的代码。 从你使用的也是同样的链接拉低数据
http://sjsharktank.com/standings.php
其实我已经使用了完全相同的XML文件，为自己的学校项目。 我用DOM文档。 该foreach循环将得到全队站立的每个属性的值和存储的值。 该代码将清除表榜上的内容，然后重新插入数据。 我想你可以做一个更新语句，但是这是假定你从来没有任何数据输入到表中。
try {
$db = new PDO('sqlite:../../SharksDB/SharksDB');
$db->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
} catch (Exception $e) {
echo "Error: Could not connect to database. Please try again later.";
exit;
}
$query = "DELETE FROM standings";
$result = $db->query($query);
$xmlDoc = new DOMDocument();
$xmlDoc->load('http://www.tsn.ca/datafiles/XML/NHL/standings.xml');
$searchNode = $xmlDoc->getElementsByTagName( "team-standing" );
foreach ($searchNode as $searchNode) {
$teamID = $searchNode->getAttribute('id');
$name = $searchNode->getAttribute('name');
$wins = $searchNode->getAttribute('wins');
$losses = $searchNode->getAttribute('losses');
$ot = $searchNode->getAttribute('overtime');
$points = $searchNode->getAttribute('points');
$goalsFor = $searchNode->getAttribute('goalsFor');
$goalsAgainst = $searchNode->getAttribute('goalsAgainst');
$confID = $searchNode->getAttribute('conf-id');
$divID = $searchNode->getAttribute('division-id');
$query = "INSERT INTO standings ('teamid','confid','divid','name','wins','losses','otl','pts','gf','ga')
VALUES ('$teamID','$confID','$divID','$name','$wins','$losses','$ot','$points','$goalsFor','$goalsAgainst')";
$result= $db->query($query);
}
