Surekha PalaparthySubject: Urgent!Help in Loop creation in XSLT
Author: Surekha Palaparthy

Hi ..i am new to XSLT ..can anyone help me..in this
My problem is something like this..
Let there be an array of Items.Items 1 to 10(Can be more,to consider only a loop).
Each item can be taken by a single person alone.But a person can take one or more items.Let there be 5 persons(Can be more , to take a loop ).
I am to loop through the data taken by each person.The XSLT has to check if the particular person number matches the value it has and give me the respective output placing a X mark saying that the particualr person has taken an item.This is a small scenario of a big XMl file that I am handling.I have made a part of XSLT and some modification is to be made in the XSLt so that my criterion can be met.

I have a call-template which calls the number of persons loop recurisvely.
I dont want to use any call-tempaltes or apply-templates as the code will become more complex.I just want to do that in a simple way where I can take up a loop.But incase if apply-templates or call-templates if the only way that I can deal with this,please let me know as to how I can go ahead ??



Original XML file is something like this:

<?xml version="1.0" encoding="ISO-8859-1"?>

<Main >
<Main1>
<Main2>
<Main3>
<Content>
<Name>NumPersons</Name>
<Value>5</Value>
</Content>
<Content>
<Name>NumItems</Name>
<Value>10</Value>
</Content>

<Content>
<Name>Item1Val</Name>
<Person>1</Person>
</Content>
<Content>
<Name>Item2Val</Name>
<Person>2</Person>

/*******************

XSLT that I made
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml" version="1.0" encoding="iso-8859-1" indent="yes"/>

<xsl:variable name= "NoPersons" select="number(Main/Main1/Main2/Main3/Content[Name='NumPersons']/Value/text())"/>
<xsl:variable name= "NoPersons" select="number(Main/Main1/Main2/Main3/Content[Name='ItemNum']/Value/text())"/>


<xsl:template match="/">
<PersonSet>
<xsl:call-template name="PersonDataBase">
<xsl:with-param name="PersonNo" select="$NumPersons"/>
<xsl:with-param name="ItemNo" select="$ItemNum"/>
</xsl:call-template>
</PersonSet>

<xsl:template name="PersonDataBase">
<xsl:param name="PersonNo"/>
<xsl:if test="$PersonNo &gt; 0" >
<ItemPresence>
<!---To write code here where he has to loop through the count of ItemNo and check for the 'present person number' if took an item.If yes he has to just put a 'X' in the output XML file
<ItemPresence>
</xsl:template>

<xsl:call-template name="PersonDataBase">
<xsl:with-param name="PersonNo" select="$PersonNo- 1"/>
<xsl:with-param name="ItemNo" select="$ItemNo"/>
</xsl:call-template>
</xsl:if>
</xsl:template>

</xsl:stylesheet>
