Update:
@c0mrade has updated his question. Here is a solution to it:
This XSLT transformation:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:strip-space elements="*"/>
<xsl:variable name="vApos">'</xsl:variable>
<xsl:template match="*[@* or not(*)] ">
<xsl:if test="not(*)">
<xsl:apply-templates select="ancestor-or-self::*" mode="path"/>
<xsl:value-of select="concat('=',$vApos,.,$vApos)"/>
<xsl:text>
</xsl:text>
</xsl:if>
<xsl:apply-templates select="@*|*"/>
</xsl:template>
<xsl:template match="*" mode="path">
<xsl:value-of select="concat('/',name())"/>
<xsl:variable name="vnumPrecSiblings" select=
"count(preceding-sibling::*[name()=name(current())])"/>
<xsl:if test="$vnumPrecSiblings">
<xsl:value-of select="concat('[', $vnumPrecSiblings +1, ']')"/>
</xsl:if>
</xsl:template>
<xsl:template match="@*">
<xsl:apply-templates select="../ancestor-or-self::*" mode="path"/>
<xsl:value-of select="concat('[@',name(), '=',$vApos,.,$vApos,']')"/>
<xsl:text>
</xsl:text>
</xsl:template>
</xsl:stylesheet>
when applied on the provided XML document:
<root>
<elemA>one</elemA>
<elemA attribute1='first' attribute2='second'>two</elemA>
<elemB>three</elemB>
<elemA>four</elemA>
<elemC>
<elemB>five</elemB>
</elemC>
</root>
produces exactly the wanted, correct result:
/root/elemA='one'
/root/elemA[2]='two'
/root/elemA[2][@attribute1='first']
/root/elemA[2][@attribute2='second']
/root/elemB='three'
/root/elemA[3]='four'
/root/elemC/elemB='five'
When applied to the newly-provided document by @c0mrade:
<root>
<elemX serial="kefw90234kf2esda9231">
<id>89734</id>
</elemX>
</root>
again the correct result is produced:
/root/elemX[@serial='kefw90234kf2esda9231']
/root/elemX/id='89734'
Explanation:
Only elements that have no children elements, or have attributes are matched and processed.
For any such element, if it doesn't have children-elements all of its ancestor-or self elements are processed in a specific mode, named 'path'. Then the "='theValue'" part is output and then a NL character.
All attributes of the matched element are then processed.
Then finally, templates are applied to all children-elements.
Processing an element in the 'path' mode is simple: A / character and the name of the element are output. Then, if there are preceding siblings with the same name, a "[numPrecSiblings+1]` part is output.
Processing of attributes is simple: First all ancestor-or-self:: elements of its parent are processed in 'path' mode, then the [attrName=attrValue] part is output, followed by a NL character.
Do note:
Names that are in a namespace are displayed without any problem and in their initial readable form.
To aid readability, an index of [1] is never displayed.
Below is my initial answer (may be ignored)
Here is a pure XSLT 1.0 solution:
Below is a sample xml document and a stylesheet that takes a node-set parameter and produces one valid XPath expression for every member-node.
stylesheet (buildPath.xsl):
<xsl:stylesheet version='1.0'
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
>
<xsl:output method="text"/>
<xsl:variable name="theParmNodes" select="//namespace::*[local-name() =
'myNamespace']"/>
<xsl:template match="/">
<xsl:variable name="theResult">
<xsl:for-each select="$theParmNodes">
<xsl:variable name="theNode" select="."/>
<xsl:for-each select="$theNode |
$theNode/ancestor-or-self::node()[..]">
<xsl:element name="slash">/</xsl:element>
<xsl:choose>
<xsl:when test="self::*">
<xsl:element name="nodeName">
<xsl:value-of select="name()"/>
<xsl:variable name="thisPosition"
select="count(preceding-sibling::*[name(current()) =
name()])"/>
<xsl:variable name="numFollowing"
select="count(following-sibling::*[name(current()) =
name()])"/>
<xsl:if test="$thisPosition + $numFollowing > 0">
<xsl:value-of select="concat('[', $thisPosition +
1, ']')"/>
</xsl:if>
</xsl:element>
</xsl:when>
<xsl:otherwise> <!-- This node is not an element -->
<xsl:choose>
<xsl:when test="count(. | ../@*) = count(../@*)">
<!-- Attribute -->
<xsl:element name="nodeName">
<xsl:value-of select="concat('@',name())"/>
</xsl:element>
</xsl:when>
<xsl:when test="self::text()"> <!-- Text -->
<xsl:element name="nodeName">
<xsl:value-of select="'text()'"/>
<xsl:variable name="thisPosition"
select="count(preceding-sibling::text())"/>
<xsl:variable name="numFollowing"
select="count(following-sibling::text())"/>
<xsl:if test="$thisPosition + $numFollowing > 0">
<xsl:value-of select="concat('[', $thisPosition +
1, ']')"/>
</xsl:if>
</xsl:element>
</xsl:when>
<xsl:when test="self::processing-instruction()">
<!-- Processing Instruction -->
<xsl:element name="nodeName">
<xsl:value-of select="'processing-instruction()'"/>
<xsl:variable name="thisPosition"
select="count(preceding-sibling::processing-instruction())"/>
<xsl:variable name="numFollowing"
select="count(following-sibling::processing-instruction())"/>
<xsl:if test="$thisPosition + $numFollowing > 0">
<xsl:value-of select="concat('[', $thisPosition +
1, ']')"/>
</xsl:if>
</xsl:element>
</xsl:when>
<xsl:when test="self::comment()"> <!-- Comment -->
<xsl:element name="nodeName">
<xsl:value-of select="'comment()'"/>
<xsl:variable name="thisPosition"
select="count(preceding-sibling::comment())"/>
<xsl:variable name="numFollowing"
select="count(following-sibling::comment())"/>
<xsl:if test="$thisPosition + $numFollowing > 0">
<xsl:value-of select="concat('[', $thisPosition +
1, ']')"/>
</xsl:if>
</xsl:element>
</xsl:when>
<!-- Namespace: -->
<xsl:when test="count(. | ../namespace::*) =
count(../namespace::*)">
<xsl:variable name="apos">'</xsl:variable>
<xsl:element name="nodeName">
<xsl:value-of select="concat('namespace::*',
'[local-name() = ', $apos, local-name(), $apos, ']')"/>
</xsl:element>
</xsl:when>
</xsl:choose>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
<xsl:text>
</xsl:text>
</xsl:for-each>
</xsl:variable>
<xsl:value-of select="msxsl:node-set($theResult)"/>
</xsl:template>
</xsl:stylesheet>
xml source (buildPath.xml):
<!-- top level Comment -->
<root>
<nodeA>textA</nodeA>
<nodeA id="nodeA-2">
<?myProc ?>
xxxxxxxx
<nodeB/>
<nodeB xmlns:myNamespace="myTestNamespace">
<!-- Comment within /root/nodeA[2]/nodeB[2] -->
<nodeC/>
<!-- 2nd Comment within /root/nodeA[2]/nodeB[2] -->
</nodeB>
yyyyyyy
<nodeB/>
<?myProc2 ?>
</nodeA>
</root>
<!-- top level Comment -->
Result:
/root/nodeA[2]/nodeB[2]/namespace::*[local-name() = 'myNamespace']
/root/nodeA[2]/nodeB[2]/nodeC/namespace::*[local-name() =
'myNamespace']
