| 32 | /** |
---|
| 33 | * CDATA sections are used to escape blocks of text containing characters that |
---|
| 34 | * would otherwise be regarded as markup. The only delimiter that is |
---|
| 35 | * recognized in a CDATA section is the "]]>" string that ends the CDATA |
---|
| 36 | * section. CDATA sections cannot be nested. Their primary purpose is for |
---|
| 37 | * including material such as XML fragments, without needing to escape all |
---|
| 38 | * the delimiters. |
---|
| 39 | * <p>The <code>data</code> attribute of the <code>DOMText</code> node holds |
---|
| 40 | * the text that is contained by the CDATA section. Note that this may |
---|
| 41 | * contain characters that need to be escaped outside of CDATA sections and |
---|
| 42 | * that, depending on the character encoding ("charset") chosen for |
---|
| 43 | * serialization, it may be impossible to write out some characters as part |
---|
| 44 | * of a CDATA section. |
---|
| 45 | * <p>The <code>DOMCDATASection</code> interface inherits from the |
---|
| 46 | * <code>DOMCharacterData</code> interface through the <code>DOMText</code> |
---|
| 47 | * interface. Adjacent <code>DOMCDATASection</code> nodes are not merged by use |
---|
| 48 | * of the <code>normalize</code> method of the <code>DOMNode</code> interface. |
---|
| 49 | * Because no markup is recognized within a <code>DOMCDATASection</code>, |
---|
| 50 | * character numeric references cannot be used as an escape mechanism when |
---|
| 51 | * serializing. Therefore, action needs to be taken when serializing a |
---|
| 52 | * <code>DOMCDATASection</code> with a character encoding where some of the |
---|
| 53 | * contained characters cannot be represented. Failure to do so would not |
---|
| 54 | * produce well-formed XML.One potential solution in the serialization |
---|
| 55 | * process is to end the CDATA section before the character, output the |
---|
| 56 | * character using a character reference or entity reference, and open a new |
---|
| 57 | * CDATA section for any further characters in the text node. Note, however, |
---|
| 58 | * that some code conversion libraries at the time of writing do not return |
---|
| 59 | * an error or exception when a character is missing from the encoding, |
---|
| 60 | * making the task of ensuring that data is not corrupted on serialization |
---|
| 61 | * more difficult. |
