Hi,
And what about problem when next node (after the interesting node)
must satisfy some condition? Let's say that node after interestingNode
must be exit (and only this node can be there). And all nodes are
encapsulated in one more, like shown below:
<encapsulating>
<interestingNode>
<con>someString</con>
<follow>
<node1>1</node1>
<test>2</test> <!-- HERE we have required node -->
<node3>3</node3>
<node4>4</node4>
</follow>
<space>5</space>
</interestingNode>
<exit /> <!-- HERE the condition -->
</encapsulating>
Thanks!

Hi,
one more question - how to enhance the condition in template to check
if among the children nodes there is <test> node. So, it should work
for:
<interestingNode>
<con>someString</con>
<follow>
<node1>1</node1>
<test>2</test> <!-- HERE we have required node -->
<node3>3</node3>
<node4>4</node4>
</follow>
<space>5</space>
</interestingNode>
but not for:
<interestingNode>
<con>someString</con>
<follow>
<node1>1</node1>
<node2>2</node2>
<node3>3</node3>
<node4>4</node4>
</follow>
<space>5</space>
</interestingNode>
Change "interestingNode[con='someString']"
to "interestingNode[follow/test and con='someString']"
thanks!

Hi guys,
I made small error in the example XMLs, actually the main problem i
had i skipped.
In the result XML, i need to get referance of attribute space of
previous node (something like preceding-sibling). If the previous node
doens't have it, i need to go further back until i find it or until
the beginning of XML.
Correct result XML would be:
<example>
<someNode>
<value>asas</value>
<name>asas</name>
<space>12</space>
</someNode>
<interestingNode>
<con>someString</con>
<follow>
<return>0</return>
</follow>
<space>5</space>
</interestingNode>
<node1 space="12">1</node1> <!-- HERE space attribute -->
<node2 space="12">2</node2>
<node3 space="12">3</node3>
<node4 space="12">4</node4>
</example>
The key difference here will be to use the xpath
'preceding-sibling::*[space]/space[1]' to pick the right space tag. The
logic here is as follows:
1) 'preceding-sibling::*' - get all preceding siblings of the current node
2) '[space]' - filter these to the ones with a 'space' child.
3) '/space[1]' - get the first 'space' child.
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="example">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="interestingNode[con='someString']">
<interestingNode>
<xsl:copy-of select="con" />
<follow>
<return>0</return>
</follow>
<xsl:copy-of select="space" />
</interestingNode>
<xsl:variable name="space"
select="preceding-sibling::*[space]/space[1]" />
<xsl:for-each select="follow/*">
<xsl:copy>
<xsl:attribute name="space" select="$space" />
<xsl:copy-of select="node()" />
</xsl:copy>
</xsl:for-each>
</xsl:template>
<xsl:template match="*">
<xsl:copy-of select="." />
</xsl:template>
</xsl:stylesheet>

Not the most imaginative title for a post.
<example>

<con>someString</con>
<follow>

<node2>2</node2>
<node3>3</node3>
<node4>4</node4>
</follow>
<space>5</space>
</interestingNode>
</example>
Now i want to transform it to:
<example>
<someNode>
<value>asas</value>
<name>asas</name>
<space>12</space>
</someNode>
<interestingNode>
<con>someString</con>
<follow>
<return>0</return>
</follow>
<space>5</space>
</interestingNode>
<node1 space="5">1</node1>
<node2 space="5">2</node2>
<node3 space="5">3</node3>
<node4 space="5">4</node4>
</example>
The changes are:
- when interestingNode is found, we check the con value
- if con value conforms someString, then we make
transformation of this part by:
- evrything in follow node is moved outside interestingNode
- follow node gets one child return
- all nodes moved outside get an attribute space with
value specified in original node
That seems to be a rule you can translate directly into XSLT:
<xsl:template match="interestingNode[con='someString']">
<xsl:copy>
<xsl:copy-of select="con"/>
<follow><return>0</return></follow>
<xsl:copy-of select="space"/>
</xsl:copy>
<xsl:variable name="space" select="space"/>
<xsl:for-each select="follow/*">
<xsl:copy>
<xsl:attribute name="space" select="$space"/>
<xsl:copy-of select="child::node()"/>
</xsl:copy>
</xsl:for-each>
</xsl:template>
