Method Details

escapeXml

public static String escapeXml(String value)

Converts the characters <, >, &, ', and " to their corresponding XML entity codes.

Returns the original value when null or empty. Only the predefined XML entities are escaped; all other characters are preserved as-is.

outWrite

public static void outWrite(@NonNull Writer out,
 String value,
 String defaultValue,
 boolean xml)
                     throws IOException

Writes a string value to the given writer, optionally escaping XML characters. When the value is null, the provided default value is used instead. If both are null, nothing is written.

The writer must not be null. XML escaping is performed using escapeXml(String).

Throws:

IOException - If an I/O error occurs while writing

NullPointerException - If the writer is null
