I want to do some tasks using XSLT 2.0. I have explained my using following example.
Input:
<code>
<bigin>
<?codestuct a?>
<butic>
<a>a</a>
<a>b</a>
</butic>
<?codestuct c?>
<butic>
<a>a</a>
<a>b</a>
</butic>
</bigin>
<medium>
<?codestuct a?>
<super>
<p>para1</p>
</super>
<?codestuct b?>
<super>
<p>para2</p>
</super>
<?codestuct c?>
<super>
<p>para3</p>
</super>
</medium>
</code>
What I wanted to was add string if <super> processing-instruction equals to the <butic> processing-instruction.
As an example,
1st <super> element processing-instruction equals to 1st <butic> processing-instruction. Then found string should be printed in output.
But 2nd <super> element processing-instruction not equals to any <butic> element.
Expected output:
<output>
<extreme>Founded</extreme>
<extreme>Not Founded</extreme>
<extreme>Founded</extreme>
</output>
Tried code:
<xsl:template match="medium">
<output>
<xsl:choose>
<xsl:when test="preceding-sibling::bigin/processing-instruction('codestuct') = super/processing-instruction('codestuct')">
<extreme>
<xsl:value-of select="'Founded'"/>
</extreme>
</xsl:when>
<xsl:otherwise>
<extreme>
<xsl:value-of select="'Not Founded'"/>
</extreme>
</xsl:otherwise>
</xsl:choose>
</output>
</xsl:template>
It is not quite clear what you want to compare and whether the elements matter but
<xsl:template match="code">
<output>
<xsl:apply-templates select="medium/processing-instruction()"/>
</output>
</xsl:template>
<xsl:template match="medium/processing-instruction()">
<extreme>Not found</extreme>
</xsl:template>
<xsl:template match="medium/processing-instruction()[some $pi in /code/bigin/processing-instruction() satisfies deep-equal(., $pi)]">
<extreme>Found</extreme>
</xsl:template>
gives
<output>
<extreme>Found</extreme>
<extreme>Not found</extreme>
<extreme>Found</extreme>
</output>
