xml xsl xpath

Hi,
I would like to know about XSL, XPATH, XML.
I see in my project code like belw

<xsl:call-template>

<xsl:with-param name="VALUE" select="lll"/>


<xsl:if test="$ABC_CD = 'AA'">
                        <xsl:call-template name="MapAmtWithKindCd">

<xPath>concat(rollNbr, '|', nbr)</xPath>
 <selectionRule>NODES_FROM_SHEET</selectionRule>





I am not clear what above code means and what it does. please advise.

Any good tutorials, resources, practice links, quiz links, video tutorials on these topics. Thanks in advance

is calling a named template (something like a function, with a variable (parameter) "VALUE" that has the value of the Ill child element
Note that this code is in error since call-template requires a known @name

<xsl:if test="$ABC_CD = 'AA'">
                        <xsl:call-template name="MapAmtWithKindCd">

Open in new window


If the variable $ABC_CD has the string value 'AA" call the template (named template behaves like a function) 'MapAmtWithKindCd'

<xPath>concat(rollNbr, '|', nbr)</xPath>
 <selectionRule>NODES_FROM_SHEET</selectionRule>

these are simply nodes that will be copied to the output tree, nothing fancy, literal results
BUT they give the impression of being a generator for some sort of XPath logic, som maybe you are generating a stylesheet generator?
