Global Variable or Container

[Former Member]

Hi Gurus,

For me there is a requirement that is in XSLT mapping, I have to count the number of records based on certain conditions in a for loop .

I think using varibales in XSLT it cant be achevied,

I thought of calling a java function using GlobalContainer but not able to count the records .

I am able to see examples using UDF in forums But not by using XSLT

Please can any one help to solve this issue

Hi,

I also think you should be able to achieve your goal in a UDF function, but in any case the xslt element that you could investigate is

<xslt:number count="xpath">

where <i>xpath</i> is an XPath expression that specifies what nodes are to be counted.

You can find more information <a href="http://www.w3schools.com/xsl/el_number.asp">here</a>.

best,

hi Daniele,

I can use count if it direct but I need to compare 2 nodes in that the records those satisify the condition should be counted

say example

<xsl:value-of select="count(ns0:Source/row/Age[text() = ns0:Source/row/Name[text()]])"/>

but not able to get the result

if i hard code i am able to

<xsl:value-of select="count(ns0:Source/row/Age[text() = 10)"/>

Hi,

>>>I thought of calling a java function using GlobalContainer but not able to count the records .

don't use GlobalContainer - just use globa variable and you'll be able to do it easily

BTW

you're function needs to be type - queue if you want to cound all lines etc

hi michal ,

Please can you brief it, see i am using XSLT mapping.

the way I tried is I try to call the java function like this from XSLT ....

XSLT----

---

<xsl:if test="function-available('ChkCounter:addCounter')">

<xsl:value-of select="ChkCounter:addCounter()" />

</xsl:if>

-

---

JAVA----

---

public static String addCounter()

{

GlobalContainer gc = container.getGlobalContainer();

Object o =gc.getParameter("counter");

try{

Integer i;

if(o==null) i = new Integer(0);

else

i = (Integer)o;

i = new Integer(i.intValue() + 1);

gc.setParameter("counter",i);

-

another way I tried was in XSLT itself

<xsl:value-of select="count(ns0:Source/row/field1[text() = ns0:Source/row/field2[text()]])"/>
