Extract Xpaths of all nodes and then their attribu

问题:

I am struggling with xslt from the past 2 days, owing to my starter status.My requirement is that given any input XML file ,I want the output to be a list of all the XPaths of all the tags in order in which they appear in the original XML document(parent, then parent,parents Attributes list/child, parent/child/childOFchild and so forth). THe XSLT should not be specific to any single XMl schema. It should work for any XML file, which is a valid one.

Ex:

If the Input XML Is :

<v1:Root>
<v1:UserID>test</v1:UserID>
<v1:Destination>test</v1:Destination>
<v1:entity name="entiTyName">
<v11:attribute name="entiTyName"/>
<v11:attribute name="entiTyName"/>
<v11:attribute name="entiTyName"/>
<v11:filter type="entiTyName">
<v11:condition attribute="entiTyName" operator="eq" value="{FB8D669E-D090-E011-8F43-0050568E222C}"/>
<v11:condition attribute="entiTyName" operator="eq" value="1"/>
</v11:filter>
<v11:filter type="or">
<v11:filter type="or">
<v11:filter type="and">
<v11:filter type="and">
<v11:condition attribute="cir_customerissuecode" operator="not-like" value="03%"/>
</v11:filter>
</v11:filter>
</v11:filter>
</v11:filter>
</v1:entity>
</v1:Root>

I want my output to be :

/v1:Root/v1:UserID
/v1:Root/v1:Destination
/v1:Root/v1:entity/@name
/v1:Root/v1:entity/v11:attribute
/v1:Root/v1:entity/v11:attribute/@name
/v1:Root/v1:entity/v11:attribute[2]
/v1:Root/v1:entity/v11:attribute[2]/@name
/v1:Root/v1:entity/v11:attribute[3]
/v1:Root/v1:entity/v11:attribute[3]/@name
/v1:Root/v1:entity/v11:filter/@type
/v1:Root/v1:entity/v11:filter/v11:condition
/v1:Root/v1:entity/v11:filter/v11:condition/@attribute
/v1:Root/v1:entity/v11:filter/v11:condition/@operator
/v1:Root/v1:entity/v11:filter/v11:condition/@value
/v1:Root/v1:entity/v11:filter/v11:condition[2]
/v1:Root/v1:entity/v11:filter/v11:condition[2]/@attribute
/v1:Root/v1:entity/v11:filter/v11:condition[2]/@operator
/v1:Root/v1:entity/v11:filter/v11:condition[2]/@value
/v1:Root/v1:entity/v11:filter[2]/v11:filter/@type
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/@type
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter/@type
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter/v11:condition
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter/v11:condition/@attribute
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter/v11:condition/@operator
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter/v11:condition/@value
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter[2]/@type
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter[2]/v11:condition
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter[2]/v11:condition/@attribute
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter[2]/v11:condition/@operator
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter[2]/v11:condition/@value
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter[2]/v11:condition[2]
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter[2]/v11:condition[2]/@attribute
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter[2]/v11:condition[2]/@operator
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter[2]/v11:condition[2]/@value

So, it is basically all the XPath of each element ,then the Xpath of the elements Attributes.

I have an XSLT with me, which is like this:

    <xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="text" indent="no" />
    <xsl:template match="*[not(child::*)]">
        <xsl:for-each select="ancestor-or-self::*">
            <xsl:value-of select="concat('/', name())" />
            <xsl:if test="count(preceding-sibling::*[name() = name(current())]) != 0">
                <xsl:value-of
                    select="concat('[', count(preceding-sibling::*[name() = name(current())]) + 1, ']')" />
            </xsl:if>
        </xsl:for-each>

        <xsl:apply-templates select="*" />
    </xsl:template>

    <xsl:template match="/">
        <xsl:apply-templates select="*" />
    </xsl:template>

</xsl:stylesheet>

THe output which gets Produced does not cater to complex tags and also the tag's attributes in the resulting Xpath list :(.

Kindly help me in fixing this xslt to produce the output as mentioned above.

THe present output from the above XSLT is like this :

/v1:Root/v1:UserID
/v1:Root/v1:Destination
/v1:Root/v1:entity/v11:attribute
/v1:Root/v1:entity/v11:attribute[2]
/v1:Root/v1:entity/v11:attribute[3]
/v1:Root/v1:entity/v11:filter/v11:condition
/v1:Root/v1:entity/v11:filter/v11:condition[2]
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter/v11:condition
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter[2]/v11:condition
/v1:Root/v1:entity/v11:filter[2]/v11:filter/v11:filter/v11:filter[2]/v11:condition[2]
/v1:Root/v1:entity/v11:filter[2]/v11:filter[2]/v11:filter/v11:condition
/v1:Root/v1:entity/v11:filter[2]/v11:filter[2]/v11:filter[2]/v11:condition
/v1:Root/v1:entity/v11:filter[2]/v11:filter[2]/v11:filter[2]/v11:condition[2]
/v1:Root/v1:entity/v11:filter[2]/v11:filter[2]/v11:filter[2]/v11:condition[3]

I think there's a discrepancy between your sample input and output, in that the output describes a filter element with two conditions that's not in the source XML. At any rate, I believe this works:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="text" indent="no" />
  <!-- Handle attributes -->
  <xsl:template match="@*">
    <xsl:apply-templates select="ancestor-or-self::*" mode="buildPath" />
    <xsl:value-of select="concat('/@', name())"/>
    <xsl:text>&#xA;</xsl:text>
  </xsl:template>

  <!-- Handle non-leaf elements (just pass processing downwards) -->
  <xsl:template match="*[@* and *]">
    <xsl:apply-templates select="@* | *" />
  </xsl:template>

  <!-- Handle leaf elements -->
  <xsl:template match="*[not(*)]">
    <xsl:apply-templates select="ancestor-or-self::*" mode="buildPath" />
    <xsl:text>&#xA;</xsl:text>
    <xsl:apply-templates select="@*" />
  </xsl:template>

  <!-- Outputs a path segment for the matched element: '/' + name() + [ordinalPredicate > 1] -->
  <xsl:template match="*" mode="buildPath">
    <xsl:value-of select="concat('/', name())" />
    <xsl:variable name="sameNameSiblings" select="preceding-sibling::*[name() = name(current())]" />
    <xsl:if test="$sameNameSiblings">
      <xsl:value-of select="concat('[', count($sameNameSiblings) + 1, ']')" />
    </xsl:if>
  </xsl:template>

  <!-- Ignore text -->
  <xsl:template match="text()" />
</xsl:stylesheet>
