Question

Hi,

I have a multiple xslt process.

I would like to divide a group, for example the party that start between
00:00:00 - 10:00:00 called as "Group A"
10:00:00 - 14:00:00 will call as "Group B"
or 14:00:00 - 20:00:00 will call as "Group C"

and I would like to record the "number" attribute where is start and end the party_group element can be anywhere, doesn't have to be at the beginning.

I'm also not sure how to do if time gt than 10:00:00 and less than 14:00:00 :confused:

So I was thinking to create another variable including the "start" element within phase1, therefore I can group by "start" date after I created the "number" then remove "start" element to get the final result. Not sure how to remove the element though :confused:

Will this be possible to do? I'm confused how to keep the start and end number. I hope someone can give me some tips. Thanks so much

Here is my input

<parties>
    <events>
        <event id="a">
            <type>dance party</type>
            <title>80s</title>
            <start>2009-12-01T00:28:30</start>
        </event>
        <event id="b">
            <type>cocktail party</type>
            <title>Flower Garden</title>
            <start>2009-12-01T10:09:34</start>
        </event>
        <event id="c">
            <type>cocktail party</type>
            <title>Prewedding party</title>
            <start>2009-12-01T14:30:34</start>
        </event>
        <event id="d">
            <type>kids party</type>
            <title>Fairy Party</title>
            <start>2009-12-01T20:00:00</start>
        </event>
        <event id="e">
            <type>kids party</type>
            <title>Animals Party</title>
            <start>2009-12-01T20:05:00</start>
        </event>
    </events>
</parties>

I would like my final result look like this

<mypartiescollection Version="1.1">
   <party_group name="Group A" fromNumber="1" toNumber="1"/>
    <party_group name="Group B" fromNumber="2" toNumber="3"/>
   <party_group name="Group C" fromNumber="4" toNumber="6"/>
    <dance_party number="1" id="a">
        <title>80s</title>
    </dance_party>
    <cocktail_party number="2" id="b">
        <title>Flower Garden</title>
    </cocktail_party>
    <cocktail_party number="3" id="c">
        <title>Prewedding party</title>
    </cocktail_party>
    <comment message="my comment" number="4"/>
    <kids_party number="5" id="d">
        <title>Fairy Party</title>
    </kids_party>
<comment message="my comment" number="5"/>
    <kids_party number="6" id="e">
        <title>Animals Party</title>
    </kids_party>
</mypartiescollection>

I have a multi phase xslt, the reason is so that I can put the number.

phase1.xslt

Hi Dear,

First, you have to separate the event timing as <start year="2009" month="12" day="01" hour="00" min="28" sec="30"/> instead of <start>2009-12-01T00:28:30</start>.

Then you use sorting the tag based on the timings. Try this.
