XML X-queries from the XML data

Hi I need some help with the xquery .I have 10 queries that has to be run.I need it by [login to view URL] are the queries . This is quite clear.I need the logic .Here is the XML document i have uploaded from which i need these xquery. I dont think its very hard .I had other projects and i am new to this so sort of just outsourcing. 1. Find the countries with emerging democracies, which continents they belong to, and the size of their population. Here is the required answer structure: <answer-1> <country>+ <name> ... </name> <continent> ... </continent> <population> ... </population> </country> </answer-1> 2. Find all the countries in Africa, with infant mortality greater than 15% and growth rate less than 2%. 3. Find the country in Europe with the largest population. 4. For each language, nest inside each language the countries where that language is spoken at least by 70% of the population. Your output should be of the form: <answer-4> <language>+ <country> ... </country>* </language> </answer-4> List the countries in increasing order of their population. 5. For each country in Asia, nd the mountains in that country and their height. Your output should be of the form: <answer-5> <country>+ <mountain> ... </mountain>* <height>...</height>* </country> </answer-5> 3 Please note that some countries will have no mountains, but they can still appear in the answer to the query. Every time that there is a mountain, then there is a height associated with it, which has to appear in the answer to the query. 6. For each country in Europe, nd the seas or oceans that surround that country. Please note that some countries will have no sea surrounding them, but they can still appear in the answer to the query. On the other hand, some countries will have more than one sea (or ocean) surrounding them, in which case all such seas/oceans need to be part of the answer. 7. Find pairs of countries that share at least one river that crosses them. Make sure that you list each pair only once (note that pairs (a,b) and (b,a) will be considered to be the same pair). Your answer may look like: <answer-7> (Country A, Country B)* </answer-7> 8. Find the countries where some ethnic group has at least 85% of the overall population. List the name of the country, the name of the ethnic group and the percentage associated with that ethnic group. 9. List the countries in Europe in descending order on the size of their population. Inside of each country, nest the provinces in decreasing order of their population. Output all population values using <population> and </population>. 10. Find the maximum depth of the XML document you were given (see [login to view URL]). Use <maxdepth> and </maxdepth> to enclose the value.
