정규 표현식 놀이 #3 - CSS

JAVA/Regular Expression / 2010. 3. 24. 22:14

HTML 의 style 속성을 가지고 이리저리 만져볼 일이 생겨서 StyleSheet 라는 클래스를 만들어 보았습니다.

package com.idstrust.wiseone.egov.xml.filter.util;

import java.util.Iterator;
import java.util.LinkedHashMap;
import java.util.Map;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class StyleSheet {

private static Pattern stylePattern;

static {
		stylePattern = Pattern.compile("([^ :]+):([^;]+)[;]?");
	}
	
	private Map<String, String> styleMap;

private StyleSheet() {
		super();
	}
	
	public StyleSheet(String style) {
		super();
		this.styleMap = parseStyleSheet(style);
	}
	
	/**
	 * style 속성을 파싱하여 Map 으로 반환합니다.
	 * 
	 * @param style
	 * @return
	 */
	private Map<String, String> parseStyleSheet(String style) {
		Map<String, String> styleMap = new LinkedHashMap<String, String>();
		
		Matcher matcher = stylePattern.matcher(style);
		while (matcher.find()) {
			String name = matcher.group(1);
			String value = removeQuotation(matcher.group(2));
			styleMap.put(name, value);
		}
		
		return styleMap;
	}
	
	/**
	 * style 값의 따옴표를 제거합니다.
	 * 
	 * @param str
	 * @return
	 */
	private String removeQuotation(String str) {
		if (str != null) {
			str = str.replaceAll("\\\"", "");
		}
		
		return str;
	}
	
	/**
	 * StyleSheet 속성을 합칩니다.
	 * 
	 * @param styleSheet
	 */
	public void merge(StyleSheet styleSheet) {
		this.styleMap.putAll(styleSheet.styleMap);
	}
	
	/**
	 * style 속성 값으로 반환합니다.
	 * 
	 */
	public String toString() {
		StringBuffer buffer = new StringBuffer();
		
		for (Iterator<String> iter = this.styleMap.keySet().iterator(); iter.hasNext(); ) {
			String name = iter.next();
			String value = this.styleMap.get(name);
			
			buffer.append(name).append(": ").append(value).append("; ");
		}
		
		return buffer.toString();
	}

/**
	 * style 을 파싱하여 Map 으로 반환합니다.
	 * 
	 * @param style
	 * @return
	 */
	public static StyleSheet parse(String style) {
		StyleSheet styleSheet = new StyleSheet(style);
		return styleSheet;
	}

}

정규식을 이용하여 style 속성을 분리하여 Map 에 담아서 슥삭슥삭 합니다.

[테스트 코드]

[출력 결과]

style-name: 바탕글; margin-left: 0.0pt; margin-right: 0.0pt; margin-top: 0.0pt; margin-bottom: 0.0pt; text-align: justify; text-indent: 0.0pt; line-height: 160%; font-size: 10.0pt; font-family: 굴림; letter-spacing: -1.5pt; font-weight: normal; font-style: normal; color: #000000;

쓰면서 슬슬 고쳐나가야 할 듯 합니다.

여기에서 P 스타일의 이름과 속성들을 개별적으로 뽑으려면 어떻게 할까요?

정규식만 잘 이용하면 CSS 파서 만드는 것도 어렵지 않을 것 같네요~
그 잘 이용하는게 어려울 뿐이죠...
