# [[PHP XML SimpleXML Get]]

## 🎯 한 줄 통찰 (One-line insight)
SimpleXML lets you access node VALUES with `->propertyName` syntax and ATTRIBUTES with `['attrName']` array-bracket syntax on the SAME object — `$xml->book[0]->title` reads a nested element, while `$xml->book[0]['category']` reads that same book's attribute, meaning the choice of `->` vs `[]` distinguishes elements from attributes throughout SimpleXML. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`->propertyName`** — reads a child element's value (e.g., `$xml->to`). [S1]
- **`[]` on an element or the root** — array-indexes into repeated sibling elements (e.g., `$xml->book[0]`, `$xml->book[1]`). [S1]
- **`['attrName']`** — reads an XML attribute's value (distinct from `->` for elements). [S1]
- **`$xml->children()`** — used inside `foreach` to loop through all repeated child elements. [S1]

## 📖 세부 내용 (Details)
- Basic node value access: `$xml = simplexml_load_file("note.xml"); echo $xml->to . "<br>"; echo $xml->from . "<br>";`. [S1]
- Indexed access into repeated elements: `echo $xml->book[0]->title . "<br>"; echo $xml->book[1]->title;`. [S1]
- Looping all books: `foreach($xml->children() as $books) { echo $books->title . ", "; echo $books->author . ", "; echo $books->year . ", "; echo $books->price . "<br>"; }`. [S1]
- Attribute access: `echo $xml->book[0]['category'] . "<br>"; echo $xml->book[1]->title['lang'];`. [S1]
- Looping attributes: `foreach($xml->children() as $books) { echo $books->title['lang']; echo "<br>"; }`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
소스에서 모순되는 정보는 발견되지 않음.

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — books.xml에서 여러 책의 제목/저자/연도/가격을 순회 출력하는 것이 SimpleXML 조회의 대표 실전 사례다. [S1]

## 💻 코드 패턴 (Code patterns)
Looping through repeated elements and their attributes (PHP):
```php
$xml = simplexml_load_file("books.xml") or die("Error: Cannot create object");
foreach ($xml->children() as $books) {
    echo $books->title . ", " . $books->author . ", " . $books->year . ", " . $books->price . "<br>";
    echo $books->title['lang'] . "<br>"; // attribute of the title element
}
```
