Java Forum / General / July 2007Problem reading " & apos; " from XML using SAX Parser
Hi All, I have a XML which contains the following element <DataText>This is simple ' Text</DataText> I have included " & apos ; " in the element called DataText. When parsing the element, am getting only the text that appears before & apos ; When Not including " & apos ; " am able to get the full text from this element. I observed that in the method characters(char buf[], int offset, int len) Thelen attribute shows the total length from start position to the position where " & apos ; "starts... How can i get the whole text which includes even " & apos ; " Thanks Note : while posting this request," & apos; " is being formatted to " ' " . thats the reason included space between them Thanks > Hi All, > [quoted text clipped - 24 lines] > > Thanks Are you getting multiple calls to your handler? How many calls (leading question) do you expect your handler to get? BugBear >I have included " & apos ; " in the element called DataText. Just like HTML, various characters are reserved and have long forms called entities to use when they occur accidentally in the text as data: &, <, >, ' and " Unlike HTML, XML just has those five basic entities. Character references take one of two forms: decimal references, ℞ and hexadecimal references, ℞. Named character entities such as é don't work. You can use any Unicode characters you want that are not part of the XML grammar, and UTF-8 deals with encoding them. If you meant the spaces in &_apos_;, it should be encoded &_apos_; If you did not mean the spaces, then it should be encoded: &apos;  SignatureRoedy Green Canadian Mind Products The Java Glossary http://mindprod.com >> I have included " & apos ; " in the element called DataText. > [quoted text clipped - 10 lines] > > If you did not mean the spaces, then it should be encoded: &apos; The OP had stated: > Note : while posting this request," & apos; " is being formatted to " > ' " . thats the reason included space between them Which leads me to wonder what they were using to enter their post. It was plain text so there shouldn't have been an issue on the Usenet side. Anyhow, it's pretty clear the OP didn't intend for the spaces to be in the final literal representation, thus they were saying "'". To make sure I understand Roedy's answer: to encode the element, instead of saying "'" the OP should say "&apos;", correct? SignatureLew >To make sure I understand Roedy's answer: to encode the element, instead of >saying "'" the OP should say "&apos;", correct? ' is the encoding for ' when you mean it as a literal character, not as a string delimiter. &apos; is the encoding for ' when it meant it as a literal string of characters not and an encoding for '. SignatureRoedy Green Canadian Mind Products The Java Glossary http://mindprod.com > I have a XML which contains the following element > [quoted text clipped - 4 lines] > When parsing the element, am getting only the text that appears before > & apos ; HOW are you parsing it? If using a DOM parser, you will likely find that the resulting tree is an element node named DataText with three children: a text node, an entity node and another text node. If you are expecting only one child and only looking at the element node's firstChild, you will find only the text before the entity. Other parsers might also split the text into separate chunks. /L SignatureLasse Reichstein Nielsen - lrn@hotpop.com DHTML Death Colors: <URL:http://www.infimum.dk/HTML/rasterTriangleDOM.html> 'Faith without judgement merely degrades the spirit divine.' Hi All, As Lasse Reichstein said, the Text between the element has been called thrice if the ''' is in middle of the Text. Am using SAX Parser extending DefaultHandler. The method characters(char buf[], int offset, int len) is being called thrice as said above. Temp'ly Resolved this by appending the text to a StringBuffer and converting that to string when the element ends. But is this the expected behavior of SAX Parser, that the parser might split the text into separate chunks if there are some entities like this in between the text ? Madan N > Hi All, > [quoted text clipped - 12 lines] > split the text into separate chunks if there are some entities like > this in between the text ? Did you read bugbear's response to your original question? Have you read the docs on the SAX callback methods? Yes, it is the expected behavior, in the sense that you do not know how many times the callback will be invoked to parse the text. It might split on any arbitrary location, not just on entities.
