In my application I need to display a list of items derived from XML.
Each item in the XML file belongs to a particular category. I want to
display this information two ways, one way would group the items by
category, the other would just list all the items. I've got a crude UI
working but right now it displays all items in the XML under each
category. I'm trying to create an Xpath which would let me select items
which have a particular category. The tricky bit is that the category is
contained in a subelement of the object I'm trying to find. For example,
my data XML looks like this:
<items>
<item name="Item 1">
<categories>
<category name="Category 1" />
</categories>
</item>
<item name="Item 2">
<categories>
<category name="Category 2" />
</categories>
</item>
<item name="Item 3">
<categories>
<category name="Category 1" />
<category name="Category 3" />
</categories>
</item>
<item name="Item 4">
<categories>
<category name="Category 2" />
<category name="Category 4" />
</categories>
</item>
</items>
So, I have a UI component which displays all the Categories 1-4. Under
Category 1, I want to find all 'item' elements who have a category element
with an attribute equal to 'Category 1'. Under Category 2, I want to list
all 'item' elements which have a category element with an attribute equal
to 'Category 2', etc.
I'm sure there must be a way to do this, but it's escaping me at the
moment.
Can anyone offer any Laszlo compatible xpath help?
Thanks
