I am new to XSL language and I get this error with edited code:
"The variable or parameter "isdocument' is either not defined or it is out of scope"

Here is my line of code I am getting the error in:

<span class="srch-Title">
<a href="{$url}" id="{concat('CSR_',$id)}" title="{$url}">

<!-- this is where the error is -->
<xsl:if test="$isdocument = 1">
<!-- this is where the error ends -->

<xsl:value-of select="filename"/>
</xsl:if>

<!-- this is where the error is -->
<xsl:if test="$isdocument = 0">
<!-- this is where the error ends -->

<xsl:choose>
<xsl:when test="hithighlightedproperties/HHTitle[. != '']">
<xsl:call-template name="HitHighlighting">
<xsl:with-param name="hh" select="hithighlightedproperties/HHTitle" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="title"/>
</xsl:otherwise>
</xsl:choose>
</xsl:if>
</a>

I'm currently stuck on this issue where sharepoint won't display the document titles but it displays the first letter inside of the document such as the title would be: B
instead of providing the documents name.

The reason I want to change this is when I search for a document I get documents that pull the first letter of the document such as when I search for the word example:

B
here is a brief example of you searched for example but the first letter in the document is B so sharepoint pulls B as the title.
www.example.com/folder/example_document.doc

And here's what I want:

Example_document.doc
here is a brief example of you searched for example but the first letter in the document is B so sharepoint pulls B as the title.
www.example.com/folder/example_document.doc

Any ideas where to start? Thanks

The message is saying you can't refer to $isdocument unless you have declared it somewhere (in an xsl:variable or xsl:param), and the declaration is "in scope", which means it is either global, or it is a preceding sibling of the an ancestor of the xsl:if instruction where the variable is referenced.

You haven't shown the whole stylesheet, so I can't tell whether the variable is undeclared, or whether the declaration is out of scope.

You never declare a variable or parameter called "isdocument" anywhere.

I had the same issue when trying to follow the instructions in this post. I eventually resolved it by adding the following line:

under the existing lines:

Hope that helps!

That isn't going to solve your problem, mealy mask the error - you've just creating a blank variable called isdocument which makes the error go away, but neither of the two xsl:if statements containing that variable will ever be true if you do that.

I think SharePoint somehow provides the value for isdocument, as it does for filename and id.
