How to Generate XPaths for All Nodes in an XML Document Using Java?

Generate/Get Xpath from XML in Java

Interested in advice rather than actual implementation. Looking for a Java approach to traverse an XML document, check nodes for attribute existence, and generate Xpaths.

Goal

To generate Xpaths for all nodes in the following 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>

Expected Result:

//root[1]/elemA[1]='one'
//root[1]/elemA[2]='two'
//root[1]/elemA[2][@attribute1='first']
//root[1]/elemA[2][@attribute2='second']
//root[1]/elemB[1]='three'
//root[1]/elemA[3]='four'
//root[1]/elemC[1]/elemB[1]='five'

Update

This solution uses an XSLT transformation to achieve the desired result:

<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 to the provided XML document, it produces the expected Xpaths.
