RE: [xsl] Navigating an XML file with xsl:for-each etc.

["Khorasani, Houman" <houman_khorasani@xxxxxxxxxxxxxx>]

Hi Peter,

Sure.  I try to explain it better this way.  The Input file is a
shopping list. :)

Only if any category has an action attribute called 'change' we would
consider it.

In this case "groceries" and "toys should have to be picked up.
Thereafter it has to be checked if any sub product exists in <add> as
well as in <delete>; in this case <food>Bread</food> has to be in the
final output.


Input:

<electronic action='add'>
	<add>
		<phone>mobile</phone>
	</add>
</electronic>
<groceries action='change'>
	<add>
		<drink>Milk</drink>
		<food>Bread</food>
		<food>fish</food>
	</add>
	<delete>
		<food>Bread</food>
		<drink>wine</drink>
	</delete>
</groceries>
<toys action='change'>
	<add>
		...
	</add>
	<delete>
		...
	</delete>
</toys>

Output:

<modified>
	<food>Bread</food>
	...
</modified>


Hopefully you know what I mean now. :)

Many thanks
Houman

Houman,

It would help us to help you if you could provide the output XML you are
looking
for.  With the given input and your explanation, it is not clear what
output XML
you want.

Hello everyone,

I have checked the FAQ but couldn't find any solution to this:

I have an XML file like this:

<a>
</a>
<b action='change'>
	<add>
		<c>bla</c>
		<d>bla</d>
	</add>
	<delete>
		<c>bla</c>
		<d>bla</d>
	<delete>
</b>
<e>
</e>


I have to check for each attribute called 'change'
	Then look if it has an <add> tag and an <delete> tag
		- Compare the sub element of <add> called <c> with the
sub 			element of <delete> called <c> and see if the
value is equal.
		- The same with sub element <d>


I guess the best to do that is to use a for-each to check all the
attributes with the value 'change' (This is not working in my example
below though)
1) How do I use for-each with attributes? Like this?

<xsl:for-each select="//[action='change']">
		<xsl:if test=".='add'">
			...
		</xsl:if>
		...
</xsl:for-each>

2) How do I compare in the most efficient way the two sub-elements <c>
and <d> against each other?


Many thanks for any idea,
Houman
