In this problem, <Image  style="vertical-align: -9pt" title="5a\frac{7b}{3}" alt="5a\frac{7b}{3}" href="http://www.snapwiz.com/cgi-bin/mathtex.cgi?%205a%5Cfrac%7B7b%7D%7B3%7D%0A"></Image> and <Image href="http://www.snapwiz.com/cgi-bin/mathtex.cgi?%207b%5Cfrac%7B5a%7D%7B3%7D" style="vertical-align: -9pt" title="7b\frac{5a}{3}" alt="7b\frac{5a}{3}"> </Image>are both mixed numbers, like <Image src="http://www.snapwiz.com/cgi-bin/mathtex.cgi?%203%20%5Cfrac%7B1%7D%7B2%7D%20=%203.5" style="vertical-align: -9pt" title="3 \frac{1}{2} = 3.5" alt="3 \frac{1}{2} = 3.5"></Image>. The expression <Image style="vertical-align: -9pt" title="5a \frac{7b}{3} \ \times 7b \frac{5a}{3}" alt="5a \frac{7b}{3} \ \times 7b \frac{5a}{3}" href="http://www.snapwiz.com/cgi-bin/mathtex.cgi?%205a%20%5Cfrac%7B7b%7D%7B3%7D%20%5C%20%5Ctimes %207b%20%5Cfrac%7B5a%7D%7B3%7D"> </Image>is equal to which of the following choices? </p>

None of the above works fine after importing xml to Indesign document/templete, it is not renderting equivalent out instead it is showing the same text inside tags in the Indesign document.
I have lot of content in our database, I will export to XML, import to Indesign, Indesign should render required output like what we see in the browser and export the output to printed format.
Import formated XML to indesign --> Export to Quality Print Format
Can any one guide me and let me know whether it is posible to do with Indesign, if so let me know in case if I am missing anything in importing xml and get required output.
Thanks in advance. Waiting for reply ASAP.

Answer 1

Possibly your expectations are too high. ... Scratch that "possibly".
XML, in general, cannot be "rendered". It's just an abstract data format. Compare it to common markup such as *asterisks* to indicate emphasized words -- e-mail clients will show this text in bold, but InDesign, and the vast majority of other software, does not.
To "render" XML, HTML, MathML, or LaTeX -- you seem to freely mix these *very* different markup formats, unaware of the fact that they are vastly different from each other! -- in the format you "expect", you need to apply the appropriate software to each of  the original data files. None of these markup languages are supported natively by InDesign.
