Interview Questions.

Question 1. What Is Xslt Data Model?

Answer :

XSLT shares the identical records model of XPATH with some additions. XSLT accepts a XSLT stylesheet as an input and output is another XML, text or another file. The version is primarily based on text nodes. These text nodes are embedded within detail nodes.

The version is a hierarchical structure like a tree. The tree has a selection of nodes like- textual content nodes, characteristic nodes, detail nodes, comment nodes, and processing training nodes. For every node type there may be a way of determining a string-fee for a node of that type.

Question 2. Explain The Role Of Xpath?

Answer :

XPATH is used to experiment the XML record for navigation of factors and attributes. It incorporates a library of widespread capabilities string advert numeric values. For navigation, XPATH makes use of direction expressions to choose nodes or units of nodes in a XML record.

Question 3. What Is Xslt Stylesheet?

Answer :

XSL stylesheet is just like a XML report used as a program textual content or a source. It carries sets of policies and commands used for alterations. XSLT stylesheet together with the XML supply documents are the inputs to the XSLT processor.

The template rule carries two elements: a pattern used to match the nodes within the source report and a template which may be instantiated to form a part of the result tree.

A stylesheet is represented by way of an xsl:stylesheet detail in an XML record.

Question 4. Explain Its Relationships Of Xslt With Xsl?

Answer :

XSLT stands for eXtensible Stylesheet Language Transformations. It is a language used to convert XML documents to XHTML or other XML documents. This conversion is executed by using transforming each XML element into an (X)HTML detail..

It uses XPath to discover information in a XML file. XSLT is not anything however reworking XSL's. Xpath defines the components of the source report that ought to fit one or greater predefined templates. Once a fit is found, XSLT will remodel the suit into the end result report.

Question eleven. Tell Me What Is Identity Template In Xsl, Why Do You Use It?

Answer :

Identity template in XSL is used to create deep replica of source XML report. It's template matches to each node() and attribute and copy the whole thing to create reproduction of authentic xml report. Many human beings outline Identity template in its personal report like Identity.Xsl but a few people additionally favored to preserve in primary XSL document as top template. Identity template has numerous makes use of in XSL transformation, like in case you want to dispose of any characteristic or element you will maximum in all likelihood copy the entirety the usage of Identity template and create any other template for not doing whatever for those characteristic or elementsnode()"/>
</xsl:copy>
</xsl:template>

Above template is called Identity template. If you observe definition first template matches any attribute or any node after which copies modern-day node together with any attributes and toddler nodes.

Question 12. Explain How To Rename A Particular Element And Attribute From Xml Using Xsl?

Answer :

Renaming attribute is also just like removing or deleting attribute as mentioned in XSLT question 1, but as opposed to no longer doing some thing whilst an characteristic matches, you need to create an characteristic and replica value of modern-day attribute into new characteristic.

Identity template will be same and also you need to feature any other template for renaming characteristic the use of XSL:

<xsl:template match="@id">

<xsl:attribute name="emp_id">

<xsl:value-of select="." />

</xsl:attribute>

</xsl:template>

if you are using XSLT 2.Zero than as opposed to separate <xsL:value-of> element you could use select attribute at once with <xsL:attribute> as shown under

<xsl:attribute name="emp_id" select=".">

Question 14. Explain How To Remove A Particular Element From Xml?

Answer :

Removing detail from XML record thru XSL transformation or XSLT is straightforward in case you are acquainted with Identity template. You need to jot down two templates one is Identity template, which copies every thing and other for matching with specific element and doing not anything much like shown underneath, a good way to then bring about elimination of a that precise element. See an instance of putting off XML factors using XSLT for details.

<xsl:template match="/root/product"/>

Question 15. How To Perform Xml Transformation In Java?

Answer :

XSL transformation is the procedure of remodeling one XML document into every other XML, HTML or other kind of file primarily based upon selective rules and condition. XSL(XML Style Sheet language) is used to define those rules and circumstance in a .Xls report, that is called style sheet record. Any XSLT engine can examine the ones coaching defined in style sheet record and rework source XML document into something predicted. Core of XSLT is, transformation engine and fashion sheet record. XSLT engine may be written in Java or some other language. Java has XSLT aid through javax.Xml.Remodel package which specifies classes like Templates, TransformFactory, an implementation of summary factory layout pattern, which may be used to study XSL record and rework XML files.

Question sixteen. How To Use Filtering Function In Xslt?

Answer :

We can filter out the XNL output with the aid of using filter out operators.Some Legal filter out operators are given underneath:

1.=(identical to)
2.!=(not identical to)
three.<(less than)
4.>(greater than)

I actually have given you a example. In this I even have uses '=' same to filer operation.

<?Xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.W3.Org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>Book Collection</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th>Title</th>
<th>Author</th>

Question 17. How We Compare Xslt And Xpath?

Answer :

Some comparison b/w XSLT and XPath and given under:

1.XSLT is depends upon W3C XPath language.Which is find to pick out subset of source report tree. XPath is also used to offer the characteristic range.

2.Both XSLT and XPath posted at same time than we are able to say that XSLT2.0 trusts on XPath2.Zero and XSLT1.0 trusts on XPath1.Zero.
