Subject [jira] Commented: (LANG-517) Define standard for escape/unescape HTML
Date Thu, 05 Nov 2009 17:31:32 GMT

    [ https://issues.apache.org/jira/browse/LANG-517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12773987#action_12773987
] 

Henri Yandell commented on LANG-517:
------------------------------------

HTML escaping:

public static final CharSequenceTranslator ESCAPE_HTML3 =
new AggregateTranslator(
new LookupTranslator(EntityArrays.BASIC_ESCAPE()),
new LookupTranslator(EntityArrays.ISO8859_1_ESCAPE()),
NumericEntityEscaper.above(0x7f)
);

public static final CharSequenceTranslator ESCAPE_HTML4 =
new AggregateTranslator(
new LookupTranslator(EntityArrays.BASIC_ESCAPE()),
new LookupTranslator(EntityArrays.ISO8859_1_ESCAPE()),
new LookupTranslator(EntityArrays.HTML40_EXTENDED_ESCAPE()),
NumericEntityEscaper.above(0x7f)
);

HTML unescaping:

public static final CharSequenceTranslator UNESCAPE_HTML3 =
new AggregateTranslator(
new LookupTranslator(EntityArrays.BASIC_UNESCAPE()),
new LookupTranslator(EntityArrays.ISO8859_1_UNESCAPE()),
new NumericEntityUnescaper()
);

public static final CharSequenceTranslator UNESCAPE_HTML4 =
new AggregateTranslator(
new LookupTranslator(EntityArrays.BASIC_UNESCAPE()),
new LookupTranslator(EntityArrays.ISO8859_1_UNESCAPE()),
new LookupTranslator(EntityArrays.HTML40_EXTENDED_UNESCAPE()),
new NumericEntityUnescaper()
);

Major question raised is why are we escaping numeric entities above 0x7f. Also request to
escape below 0x20.
