Congrats Samba,
You matched my score.
Jim,
I would say the actual exam is very similar to the new sample test. I had scored 90% on new sample test (that had 30% of questions from old sample exam) and got 87% on actual exam (not many question from old mock exam but definately 10-15% very similar questions from new sample exam). Go for it. You'll surely do well. Best of luck.
Congrats Vasudha.

Congratulations Richard. Good Score.

XML paresers implementations vary for this.
According to W3 Specs.
1) No ELEMENT can be declared twice.
2) ATTRIBUTE can be declared more than once BUT only first ATTRIBUTE declaration is binding. If two ATTLIST is defined for an ELEMENT, attribute definations will be merged (i.e. new attributes defined in subsequent ATTLIST will be added to ATTLIST)
3) ENTITY can be declared more than once BUT only First ENTITY declaration is binding.
4) Only one notation declaration can declare a given Name
Hi,
Actually above example document is perfectly valid. You can use ":" character for/within Element and Attribute name in DTD. So even though it looks like a name space declaration, it is not. One possible practical scenario for this would be :-
Company A has an XML application that uses DTD for validation. Company B has an XML application that uses Schema for validation. Now Company A receives the instance document from company B. Company A may develop a DTD like above to validate the incoming XML document. Probably this would be quickest/easy solution for company A to validate Company B's XML.
I took sample test 3 times in last week.
Beginning of this week they had 57 question. On 17th I noticed they had 44 questions. I couldn't find any details for new format on IBM site and was wondering before going to Exam. But in actual exam its 55 question with passing of 58%.
Thanks guys.
DOM/SAX questions are similar to what IBM have in sample test. They had couple of scenario based qustion on SAX/DOM. Understanding of SAX/DOM/NodeFilter/NodeIterator/TreeWalker would definately help. I had scored 90% in new sample test which definately built my confidence up.
Schema questions: what is a correct instance document defination for given Schema. Advantages of schema over dtd for given practical scenario. Which of the following is not true about schema and DTD. What technologies to use to improve performance of existing xml aplication. I saw XMLQuery as on of the option in couple of questions. Lot of questions were scenario related.
XSLT question: 2 direct question on given xml, given output, what would be correct template defination.
I will try to post more details.
Today I cleared the 141 test with 87%. Thanks to all you folks at Javaranch. I had prior working experience with XML which made it little easier for me. I had 17 minutes left after first round of answers with 14 questions marked. I changed answers for 4 of them. It was a pleasant surprise to see such a good score.
Actual Exam:-
No. of questions are 55 and passing score required is now 58%. Otherwise I didn't see any difference in format with compare to IBM sample exam.
Architecture 18%
Info.Modeling 27%
XML Processing 33%
XML Rendering 11%
Testing and Tuning 11%
Sample Exam:-
Last night, I took IBM's sample test which now asks 44 questions to be answered in 90 minutes. IBM have added more/different questions to sample exams now.
