Ignoring some tags for LaTeX documents

5

Ok, I’ve found a simple solution: replace everything between and with empty string and disable WHITE_SPACE rule.

/**
* Empty string of length len
* @param leng
* @return
*/
public static String padString(int leng) {
StringBuffer str= new StringBuffer();;
for (int i =0; i <leng; i++) str.append(" ");
return str.toString();
}

/**
 * Replace latex tags preserving document structure
 * @param text
 * @return
 */
public static String modifyLatexTags(String text) {
    
	// replace between $ and $
	Pattern p = Pattern.compile("\\$[^\\$]*\\$");
	Matcher m = p.matcher(text);
	while(m.find()){
	    String d = text.substring(m.start(), m.end());
	    String empty=padString(d.length());
	    text = text.replace(d, empty);
	}

	return text;
}

best, Sergei
