Expose a public method to escape characters within an attribute #1278
Description
Hello
I need to escape the characters within an attribute in a program that converts an HTML file into a single Java class with a single public static method that converts the Java source code into HTML:
https://github.com/gouessej/HtmlFlow/blob/patch-1/src/main/java/htmlflow/flowifier/AbstractHtmlToJavaHtmlFlowNodeVisitor.java#L319
The package protected static method named "escape" does the correct job by passing inAttribute at true but I can't call it in the source code above because it's not public. Please can you provide a public method that allows to pass inAttribute at true? It would be cleaner than my dirty kludge that doesn't take into account some other cases.
I suggest the addition of the following method:
/**
* HTML escape an input string within an attribute.
*
* @param string the un-escaped string within an attribute to escape
* @param out the output settings to use
* @return the escaped string
*/
public static String escapeInAttribute(String string, Document.OutputSettings out) {
if (string == null)
return "";
StringBuilder accum = StringUtil.borrowBuilder();
try {
escape(accum, string, out, true, false, false);
} catch (IOException e) {
throw new SerializationException(e); // doesn't happen
}
return StringUtil.releaseBuilder(accum);
}
Best regards and keep up the good work.
