Trouble with XPath for "preceding sibling"

[apurvaG]

Hi All,

I am facing a problem while fetching a preceding sibling with some specific name from current node.

Following is the sample XML which I am using

<Root>
<document>
<tid>100</tid>
<location>SB</location>
<category>C1</category>
</document>
<document>
<tid>101</tid>
<location>SB</location>
<category>C3</category>
</document>
<document>
<tid>102</tid>
<location>JK</location>
<category>C4</category>
</document>
</Root>

Now suppose I am on 3rd <document> node [that is "tid = 102" ] and I want to check the values for the previous document's <location> node. If its is different than the current document's <location> then I need to call some other template.

Can anyone please help. This is very urgent!


Thanks in advance

[code=xml]
<xsl:if test="location != preceding-sibling::tid[1]/location">
<xsl:call-template name="blah">
..
[/code]

[code=xml]
<xsl:if test="location != preceding-sibling::tid[1]/location">
<xsl:call-template name="blah">
..
[/code]

Will "preceding-sibling::tid[1]/location" refer to 2nd <document> node's locaton ? Another thing is location node is not child of <tid>. It is child of <document> node.

sorry, must have been a brain fart:
[code=xml]
<xsl:if test="location != preceding-sibling::docume nt[1]/location">
<xsl:call-template name="blah">
..
[/code]
