From: shahrzad khorrami on 18 Jul 2010 01:19 hi all :) here is a xml file: <directive> <rule> <rules> <rule> </rule> <rule> </rule> </rules> </rule> </directive> <directive> <rule> <rules> <rule> </rule> <rule> </rule> </rules> </rule> </directive> .. .. .. ...... I have a xml file with a name for example(test.xml).. and 3 tables of database, (group,directives,rules) group is for recording the name of the opened xml file, directives is for storing the attributes of directive tag and rules is for 'rule' tag's attributes. I know I must use of recursive function.. but how? first read name of the xml file and store it in group table, then the content of the file and fill the directive and rules table... <directive .*... attrs go to directives table..*.> <rule * ...attrs go to rules table...*.> <rules * ..no attrs.*.> <rule *...attrs go to rules table...*.> </rule> <rule *...attrs go to rules table..*..> </rule> </rules> </rule> </directive> how to implement it in php? Thanks, Shahrzad

I assume there may be multiple xml files you need to parse? What you need is a series of nested loops. The first one loops through the list of xml filenames you need to parse (you can get this list from a directory listing if you need), the second goes through each <directive> tag, the third through the <rule> tags. The attributes of each tag can be pulled out quite easily. Are these a list of known attributes, or unknown? If you know what they are, you can hard-code retrieving their values, but if not, another loop will be able to fetch these out for you. Thanks, Ash http://www.ashleysheridan.co.uk |
