[英]simple html dom parsing first child into an array
考慮如下 html 代碼
<html>
<div class="allItems">
<div class="Item" id="12345">
<div class="ItemName">Tom</div>
<div class="ItemAge">34</div>
<div class="ItemGender">male</div>
</div>
<div class="Item" id="17892">
<div class="ItemName">Dick</div>
<div class="ItemAge">23</div>
<div class="ItemGender">male</div>
</div>
<div class="Item" id="98776">
<div class="ItemName">Harry</div>
<div class="ItemAge">65</div>
<div class="ItemGender">male</div>
</div>
</div>
</html>
我試圖解析這個 html 文檔如下:
<?php
include_once("/simple_html_dom.php");
<--a bunch of code that works until here -->
$html = str_get_html($str); //this pulls the html code fine
//this is where my array constructions does not work
foreach ($html->find('div.allItems > *') as $article) {
$item['name'] = $html->find('div.ItemName', 0)->plaintext;
$item['age'] = $html->find('div.ItemAge',0)->plaintext;
$item['gender'] = $html->('div.ItemGender', 0)->plaintext;
$articles[] = $item;
}
print_r($articles);
?>
Array ( [0] => Array ( [name] => Tom [Age] => 34 [Gender] => male )
[1] => Array ( [name] => Dick [Age] => 23 [Gender] => male )
[2] => Array ( [name] => Harry [Age] => 65 [Gender] => male )
Array ( [0] => Array ( [name] => Tom [Age] => 34 [Gender] => male )
[1] => Array ( [name] => Tom [Age] => 34 [Gender] => male )
[2] => Array ( [name] => Tom [Age] => 34 [Gender] => male )
如何獲得所需的數組?
您走對了,唯一的想法是您需要將 div 的索引設置為find
函數的第二個參數。 看看下面的解決方案:
include_once("simple_html_dom.php");
$str = '<html>
<div class="allItems">
<div class="Item" id="12345">
<div class="ItemName">Tom</div>
<div class="ItemAge">34</div>
<div class="ItemGender">male</div>
</div>
<div class="Item" id="17892">
<div class="ItemName">Dick</div>
<div class="ItemAge">23</div>
<div class="ItemGender">male</div>
</div>
<div class="Item" id="98776">
<div class="ItemName">Harry</div>
<div class="ItemAge">65</div>
<div class="ItemGender">male</div>
</div>
</div>
</html>';
$html = str_get_html($str); //this pulls the html code fine
//this is where my array constructions does not work
$i = 0;
foreach ($html->find('div.allItems > *') as $article) {
$item['name'] = $html->find('div.ItemName', $i)->plaintext;
$item['age'] = $html->find('div.ItemAge',$i)->plaintext;
$item['gender'] = $html->find('div.ItemGender', $i)->plaintext;
$articles[] = $item;
$i++;
}
print_r($articles);
輸出:
Array
(
[0] => Array
(
[name] => Tom
[age] => 34
[gender] => male
)
[1] => Array
(
[name] => Dick
[age] => 23
[gender] => male
)
[2] => Array
(
[name] => Harry
[age] => 65
[gender] => male
)
)
