Php从字符串中的特定标签获取值

I have a string

我有一个字符串

$string= '<Label>1</Label><Value>1</Value><Label>2</Label><Value>2</Value><Label>3</Label><Value>3</Value><Label>4</Label><Value>4</Value><Label>5</Label><Value>5</Value>';

I need to separate the Label and Value tag values into two separate arrays. I tried to use the following function

我需要将Label和Value标记值分成两个单独的数组。我试着使用以下功能

function getTextBetweenTags($string, $tagname) 
{
    $pattern = "/<$tagname>(.*)<\/$tagname>/";
    preg_match($pattern, $string, $matches, PREG_OFFSET_CAPTURE);
    return $matches;
}

I created another function to make it two separate arrays

我创建了另一个函数来使它成为两个独立的数组

function formatChoices($choices)
{
    $return['label'] = $this->getTextBetweenTags($choices, "Label");
    $return['value'] = $this->getTextBetweenTags($choices, "Value");

    return $return;
}

But it returns the following

但它返回以下内容

Array([label] => Array(
        [0] => 1</Label><Value>1</Value><Label>2</Label><Value>2</Value><Label>3</Label><Value>3</Value><Label>4</Label><Value>4</Value><Label>5
        [1] => 7
    )

[value] => Array
    (
        [0] => 1</Value><Label>2</Label><Value>2</Value><Label>3</Label><Value>3</Value><Label>4</Label><Value>4</Value><Label>5</Label><Value>5
        [1] => 23))

Please help. Thanks

Try this code.

试试这个代码。

<?php
$string= '<Label>1</Label><Value>1</Value><Label>2</Label><Value>2</Value><Label>3</Label><Value>3</Value><Label>4</Label><Value>4</Value><Label>5</Label><Value>5</Value>';
$array = json_decode(json_encode((array) simplexml_load_string('<data>'.$string.'</data>')),1);
print_r($array);
?>

#2

The inside of tags cannot have '<' and '>' character, so change it this way

标签内部不能包含“<”和“>”字符，因此请按此方式更改

$pattern = "/<$tagname>([^<>]*)<\/$tagname>/";

PS For XML Manipulation it is better to use SimpleXML or DOM or ...

PS对于XML操作，最好使用SimpleXML或DOM或...

The problem is the point it tries to match as match as possible. (The point is greedy.)

问题是它试图匹配尽可能匹配。（关键是贪心。）

Edit: This should work:

编辑：这应该工作：

$pattern = "/<$tagname>(.*?)<\/$tagname>/";
