hi! i'm relatively new to xpath and im trying to include a search facility in my website which searched through my xml file.
the format of the xml file is as follows:
<years> <year> <life> <title>...title...</title> <full>...full text... </full> </life> </year> ..... </years>
i need to retrieve all the categories (eg "life") that contain a specific string. at this point the query that i have is:
//year/*/*[contains(., '$string')] , which retrieves the inner nodes (title and full). however, if the string is contained in both the title and the full text, the category is returned twice. is there any way to get the parent directory automatically (and only once) if the inner nodes contain the string, or, if found in the title then skip to the next parent directory without going though the full text?
many thanks! anna
