Subject: [xsl] Flat XML: Problem getting children From: "Jacqui Moore" <jacquimoore1@xxxxxxxxxxx> Date: Thu, 7 Oct 2004 17:26:56 +0100 |
I have an xml file that has the following structure: <thesaurus> <concept> <descriptor>House</descriptor> <NT>Rooms</NT> <NT>Roofs</NT> <SN>All About houses</SN> </concept> <concept> <descriptor>Rooms</descriptor> <BT>House</BT> <NT>Lounge</NT> <NT>Kitchen</NT> <SN>We have rooms in houses</SN> </concept> <concept> <descriptor> Lounge </descriptor> <BT> Rooms </BT> <SN>Lounges are nice places</SN> </concept> <concept> <descriptor> Roofs </descriptor> <BT>House</BT> <NT>Kitchen</NT> <SN>Roofs go on houses</SN> </concept> <concept> <descriptor> Utensils </descriptor> <BT>Kitchen</BT> <SN>Utensils belong in the draw</SN> </concept> </thesaurus> NT - the children categories BT - the parent category The objective is to create a expandable client side tree structure, and the user will click on a category and the category information (SN) will be displayed in the right frame. - HOUSE - Rooms o Lounge o Kitchen ' Utensils - Roofs o Kitchen ' Utensils I can get the top level categories: <xsl:for-each select="thesaurus/concept[boolean(BT)=false]"> My problem is I do not know how to get the children and their children etc. (loop until the concept has no NT element) . There is no limit to the number of children levels and a child can appear in more than one parent. I think I need to use a key but am not having ANY success. Thanks in advance!! Jacqui
