My xml looks like this :
<customers>
<customer>
<city>a</city>
<name>Jhon<name>
</customer>
<customer>
<city>b</city>
<name>Don<name>
</customer>
<customer>
<city>c</city>
<name>Ron<name>
</customer>
</customers>
The data is to presented in a table and I want to filter it according to
the "city" - meaning I have 4 options :
1.a
2.b
3.c
4.all the cities = no filter
Im using a html select box to let the user choose which city to filter
and the first option is "all cities".for this parameter I give the value
*.
The xsl looks like this :
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:output method="xml" encoding="windows-1255" />
<xsl:param name="city" />
<xsl:template match="/">
<customers>
<xsl:for-each
select="customers/customer[city=$city]">
<customer>
<xsl:for-each select="*">
<xsl:element
name='{name()}'>
<xsl:value-of
select="." />
</xsl:element>
</xsl:for-each>
</customer>
</xsl:for-each>
</customers>
</xsl:template>
</xsl:stylesheet>
When choosing "all cities" - the result is an empty table instead of the
list of all cities with the customers names.
I tried to giva the param "city" a diect value of "*" or " '*' " and it
still didn't work.
How can I pass a value to this param which will act like : <xsl:for-each
select="customers/customer[city=*]"> ??
Don't forget to quote the *.
It looks to me like your conditions are as follows:
If $city = '*', you want all customer elements.
If $city != '*', you want all customer elements for which child::city = $city.
Rephrase this into a test for each customer element:
You want all customer elements for which:
$city = '*' is true
or
child::city = $city
The answer, unless I've overlooked something, is:
customers/customer[$city='*' or city=$city]
Another option is to let $city be an empty string to indicate "all cities".
Then you'd use:
customers/customer[not($city) or city=$city]
Also note that instead of <xsl:element name="{name()}">...</xsl:element>
you can use <xsl:copy>...</xsl:copy>.
