Hi, all: Now I have three XML files, c1.xml, c2.xml, c3.xml. Each XML file contains information of one company, and of parts supplied by it. Given a part id, I want to get the company which offered this part with the lowest price. How can I write this XQuery? -----begin of source data---- c1.xml: <company> <name>CompanyA</name> <parts> <part> <id>p1</id> <price>100</price> </part> <part> <id>p2</id> <price>101</price> </part> </parts> </company> c2.xml: <company> <name>CompanyB</name> <parts> <part> <id>p2</id> <price>105</price> </part> <part> <id>p3</id> <price>106</price> </part> </parts> </company> c3.xml: <company> <name>CompanyC</name> <parts> <part> <id>p2</id> <price>100</price> </part> <part> <id>p6</id> <price>106</price> </part> </parts> </company> -----end of source data---- -----begin of expected result---- <result> <part> <id>p2</id> <price>100</price> <company>CompanyC</company> </part> </result> -----end of expected result---- Who would like to give me a hand?
