Question

所以我得到了这个XML。我在XML中获得了很多这样的类似块，我可以遍历它。但我怎么知道有多少块？或者在最后一个街区后如何停止？

任何建议都表示赞赏。

Answer 1

我会尝试尝试this之类的东西。为了节省链接之旅，这里有一些示例代码可以帮助您入门。

<?php
$xml = <<<EOF
<people>
 <person name="Person 1">
  <child/>
  <child/>
  <child/>
 </person>
 <person name="Person 2">
  <child/>
  <child/>
  <child/>
  <child/>
  <child/>
 </person>
</people>
EOF;

$elem = new SimpleXMLElement($xml);

foreach ($elem as $person) {
    printf("%s has got %d children.\n", $person['name'], $person->count());
}
?>

Answer 2

从您的XML中，我获得了这些信息。 <StockBalanceOut>有多个“块”，您可以通过以下方式访问每个块： -

$objectOfXMLFile->StockBalanceOut[0];
$objectOfXMLFile->StockBalanceOut[1];

要到达终点，您可以运行一个while循环。如果StockBalanceOut的任何索引（假设10不存在）不存在，那么它将返回null。

 $counter=0; //run from 0
    while(!is_null($xmlOBJ->StockBalanceOut[$counter]))
    {
//do anything here
    $counter++;
    }

到达最后一个XML元素
