| This XQuery loads a GCC-XML file and reports the locations of all |
| global variables in the original C++ source. To run the query, |
| use the command line: |
| |
| xmlpatterns reportGlobals.xq -param fileToOpen=globals.gccxml -output globals.html |
| |
| "fileToOpen=globals.gccxml" binds the file name "globals.gccxml" |
| to the variable "fileToOpen" declared and used below. |

| |
| declare variable $fileToOpen as xs:anyURI external; |
| declare variable $inDoc as document-node() := doc($fileToOpen); |

| This function determines whether the typeId is a complex type, |
| e.g. QString. We only check whether it's a class. To be strictly |
| correct, we should check whether the class has a non-synthesized |
| constructor. We accept both mutable and const types. |
| :) |
| declare function local:isComplexType($typeID as xs:string) as xs:boolean |

| exists($inDoc/GCC_XML/Class[@id = $typeID]) |

| This function constructs a line for the report. The line contains |
| a variable name, the source file, and the line number. |
