10 Xslt Or Xml, Xsl Transformation Interview Questions In Addition To Answers

XSLT stands for XML mode canvass transformation together with it every bit XML applied scientific discipline used to transform 1 XML into roughly other XML or HTML format.  XML together with XSLT interview questions are ordinarily asked Java developers, who hand to work XML inwards their projection together with mentioned XSLT every bit a key science inwards their resume. Given XML’s popularity every bit information transfer protocol, many systems inwards center together with dorsum percentage infinite uses XML messages to transfer merchandise details, for example, Bookings, Settlement, together with Confirmation organisation work it every bit a information telephone substitution protocol. Since each of this organisation performs roughly normalization, enrichment, together with transform on incoming merchandise message, they work XSLT for that transformation. XSLT is rich, powerful together with given its back upward inwards Java together with several other programming languages, it comes the natural selection of XML transformation. What y'all demand to is to write XSL files, too known every bit XML mode canvass to specify your transformation dominion together with hence XSLT engine volition transform each incoming XML documents every bit per your XSL file. 

Though, XSLT is rich, it’s tin send away too last real complex for Java programmers, who are used to procedural mode of coding, every bit XSLT uses recursion a lot. So if y'all are a Java programmer, who bring used XSLT or going for a Job interview, where XSLT is a key skill, y'all improve last create amongst roughly pop XSLT interview questions.

In this article, I am sharing my listing of XSLT questions, which is collected from internet, friends together with colleagues together with often asked every bit part of XML Interview questions.

XSLT or XML transformation Interview Questions Answers

Here is my listing of XSLT questions, which is often asked to Java developers for projects, who uses XML extensively for transferring data, generating dynamic HTML together with other XML transformation task. Though these XSLT interview enquiry are non real difficult, but they tin send away last tricky, given XSLT non beingness Java programmers primary pull together with lack of fourth dimension on learning XSLT. You tin send away work these questions for grooming or refreshing your noesis earlier going for whatever Java together with XML based Job interview.

Question 1: What is XSL transformation or XSLT? How attain y'all perform XML transformation inwards Java?

Answer : XSL transformation is the physical care for of transforming 1 XML file into roughly other XML, HTML or other type of file based upon selective rules together with condition. XSL(XML Style Sheet language) is used to define those rules together with status inwards a .xls file, which is called style canvass document. Any XSLT engine tin send away read those didactics defined inwards mode canvass document together with transform source XML file into something expected. Core of XSLT is, transformation engine together with style sheet  document. XSLT engine tin send away last written inwards Java or whatever other language. Java has XSLT back upward via javax.xml.transform bundle which specifies classes similar Templates, TransformFactory, an implementation of abstract manufacturing works life blueprint pattern,  which tin send away last used to read XSL file together with transform XML files. See XSL transformation inwards Java for to a greater extent than details

Question 2: How to take away a exceptional chemical factor from XML?

Answer : Removing chemical factor from XML document via XSL transformation or XSLT is slowly if y'all are familiar amongst Identity template. You demand to write ii templates 1 is Identity template, which copies every matter together with other for matching amongst exceptional chemical factor together with doing nada simply similar shown below, which volition hence upshot inwards removal of a that exceptional element. See an event of removing XML elements using XSLT for details.

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

Question 3: How to take away a exceptional attribute from XML?

Answer : Process of removing an attribute is similar to removing elements from XML document, every bit discussed inwards higher upward XSLT interview question. Along amongst Identity template, define roughly other template to jibe amongst that exceptional attribute every bit shown below.

<xsl:template match="@product_synonym"/>

Question 4: How to rename a exceptional chemical factor together with attribute from XML using XSL?

Answer : Renaming attribute is too similar to removing or deleting attribute every bit discussed inwards XSLT enquiry 1, but instead of non doing anything when an attribute matches, y'all demand to create an attribute together with re-create value of electrical flow attribute into novel attribute. Identity template volition last same together with y'all demand to add together roughly other template for renaming attribute using XSL:

<xsl:template match="@id">

    <xsl:attribute name="emp_id">

         <xsl:value-of select="." />

    </xsl:attribute>

</xsl:template>

if y'all are using XSLT 2.0 than instead of split upward <xsL:value-of> chemical factor y'all tin send away work direct attribute straight amongst <xsL:attribute> every bit shown below

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

Question 5: What is Identity template inwards XSL,  why attain y'all work it?

Answer : Identity template inwards XSL is used to create deep re-create of source XML file. It's template matches to every node() together with attribute together with re-create everything to create re-create of master copy xml file. many people define Identity template inwards its ain file similar Identity.xsl but roughly people too preferred to travel past times away along inwards primary XSL file every bit top template. Identity template has several uses inwards XSL transformation, similar if y'all desire to take away whatever attribute or chemical factor y'all volition most probable re-create everything using Identity template together with create roughly other template for non doing anything for those attribute or elements every bit discussed inwards XSLT interview questions 1 together with 2.

<xsl:template match="@|node()">

   <xsl:copy>

       <xsl:apply-templates select="@|node()"/>

   </xsl:copy>

</xsl:template>

Above template is called Identity template. If y'all facial expression at Definition starting fourth dimension template matches whatever attribute or

any node together with hence copies electrical flow node including whatever attributes together with modest fry nodes.

Question half dozen : Why nosotros work select="@|node()" inwards the <xsl:apply-templates/> chemical factor on Identity template? what volition hand if nosotros work <xsl:apply-templates/> without direct attribute?

Answer : This is an extension or follow upward questions of previous XSLT enquiry nearly Identity template. nosotros work select="@|node() to re-create all modest fry chemical factor together with whatever attribute.if nosotros don't work that than <xsl:apply-templates/> volition default on select="node()" which volition re-create modest fry nodes except attributes.

Question 7:  Can y'all explicate me this XSL template? What output this XSL template volition attain given a exceptional xml file?

Answer : This form of XSL transformation questions are to a greater extent than pop to approximate existent agreement of templates. they tin send away write template inwards front end of y'all together with may inquire y'all to explain, most elementary event of this is writing Identity template every bit discussed inwards XSLT interview enquiry 3. Alternatively they may give y'all XSL together with XML file together with inquire y'all nearly around of transformation. This are tricky questions inwards XSL together with inwards gild to reply these enquiry y'all demand to last familiar amongst XSL language, which is the primary argue people inquire it. On the other mitt this is an fantabulous chance to exhibit y'all how good y'all know nearly XSL working or how template executes, past times clearly explaining what a exceptional template does.

Question 8 : How to recollect value of an attribute for an chemical factor using XSLT?

Answer : This XSLT interview enquiry is pretty mutual inwards many XML interviews every bit well. If candidate has worked inwards XSLT hence this is a fairly slowly enquiry every bit it simply demand to come upward up amongst a XSLT template which tin send away re-create an attribute from an chemical factor similar below:

<xsl:template match="/employees/employee">

Value of attribute Id is :

<xsl:value-of select="@id"></xsl:value-of>

</xsl:template>

Question ix : How attain y'all generate dynamic HTML pages from relational database using XSLT?

Answer : This is 1 of the XSLT interview questions which checks practical noesis of candidate inwards XSL. This is 1 of the most mutual application of XSLT I bring seen where information stored inwards relational database is converted into XML together with past times using XSLT transformed into HTML pages. Database stored procedure can last used for starting fourth dimension percentage together with having all the logic of rendering HTML inwards XSLT y'all don't demand to modify your query instantly together with hence if y'all demand to modify construction of HTML pages. If candidate successfully reply this XSLT interview enquiry hence at that spot is real skillful risk that he has a skillful agreement of how things works amongst database, xml together with XSLT.

Now let’s come across span of XSLT Interview enquiry for practice, y'all demand to honour reply of these ii questions past times yourself, together with in 1 lawsuit y'all honour the answer, y'all tin send away too post them every bit comment here. The reason, I am non giving reply of these enquiry hither because, they are extremely basic together with should come upward every bit experience, i.e. y'all would improve write code for that. That volition enable y'all to sympathize other XSLT questions every bit well.

That’s all on my listing of XSLT together with XML transformation interview questions together with answers. XSLT is 1 of the of import science to bring inwards your resume, if y'all are using XML inwards your project. Since XML is to a greater extent than often than non used every bit shipping protocol together with center together with dorsum percentage systems, those roles facial expression for candidates which are skillful inwards XML, XSL together with XSLT transformation. So if y'all are applying for whatever center together with dorsum percentage Java evolution purpose inwards Investment banks, brand certain to create XSLT well.
