XSL check param length and make a choice - xslt

I need to check if a param has got a value in it and if it has then do this line otherwise do this line.
I've got it working whereas I don't get errors but it's not taking the right branch
The branch that is wrong is in the volunteer_role template

The following should do the trick:
<xsl:template name="volunteer_volid">
<xsl:param name="volid" />
<xsl:choose>
<xsl:when test="string-length($volid) > 0">
<div class="heading2 bold"><h2>VOLUNTEER ID: <xsl:value-of select="$volid" /></h2></div>
</xsl:when>
<xsl:otherwise>
<!-- No volid -->
</xsl:otherwise>
</xsl:choose>
</xsl:template>
I've replaced the default value with an empty string so that not providing a parameter value is the same as providing the parameter value as "". If this isn't the desired behaviour then change the parameters select and modify the test expression accordingly, for example:
$volid != 'Not Available'

XSLT - Choose between one of 2 Sitecore fields

I am very new to XSLT and am trying to edit some code that sets up the breadcrumb navigation for a Sitecore site. Right now, it's set to get the value of the Menu Title field and use that for the breadcrumb navigation. However, there are templates that don't have this field, so I would like to have the option to get the value of Page Title's field in these cases.
I can do this sort of thing with C#, but XSLT is completely different. Any suggestions?
Here is the complete XSLT file:
<?xml version="1.0" encoding="UTF-8"?>

<xsl:when test="sc:fld( 'navtitle', $item )">
<xsl:value-of select="sc:fld( 'Menu Title', $item )" />

<xsl:otherwise>
<xsl:variable name="holder" select="$item/#id" />
<!--<xsl:value-of select="$item/#name" />-->
<xsl:value-of select="sc:fld('Menu Title', sc:item($holder,.))" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>

Your XSLT needs to be changed to this:
<xsl:choose>
<xsl:when test="sc:fld( 'Menu Title', $item ) != '' ">
<xsl:value-of select="sc:fld( 'Menu Title', $item )" />
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="sc:fld('Page Title', $item )" />
</xsl:otherwise>
</xsl:choose>

Your problem is that all of the elements are in the file://Volumes/u1234567/Assignment namespace, but in your XSLT your templates are matching on elements without a namespace.
If you look closely at the <catalogue> you will see a namespace declaration without a prefix. <catalogue xmlns="file://Volumes/u1234567/Assignment" All of the descendant elements inherit that namespace.
Define that namespace with a prefix in your XSLT and then change the places where you refer to those elements to use that namespace prefix:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

Xslt extracting attributes and generating html

I'm trying to transform the following XML..
<?xml version="1.0" encoding="utf-16"?><Member TextRank="unknown" FullName="My Name" ..etc.. />
Into something like the following,
<div class="member">
<span class="label">
Text Rank (note: i want to override the labels in the xslt)
</div>
<span class="value">
unknown
</span>
<span class="label">
Full Name
</div>
<span class="value">
My Name
</span>
..etc..
</div>
How if possible could I do this using xslt?

Here's a different approach, that does away for the need for the xsl:choose element. Instead, you could take advantage of the matching templates to have specific templates for the cases of attributes who names you want to override, and a generic template for other case.
To avoid repetition of code, you could also make the generic template a named template, with a parameter to override the name
<xsl:template match="#*" name="attribute">
<xsl:param name="label" select="local-name()" />
So, the default for most attributes would be to use the attribute name, but the specific template for #FullName could then call this with a different name.
<xsl:template match="#FullName">
<xsl:call-template name="attribute">
<xsl:with-param name="label" select="'Full Name'" />
</xsl:call-template>
</xsl:template>
Here is the full XSLT:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes"/>
<xsl:template match="*">
<div class="{local-name()}">
<div> Title: </div>
<xsl:apply-templates select="#*"/>
</div>
</xsl:template>
<xsl:template match="#FullName">
<xsl:call-template name="attribute">
<xsl:with-param name="label" select="'Full Name'" />
</xsl:call-template>
</xsl:template>
<xsl:template match="#*" name="attribute">
<xsl:param name="label" select="local-name()" />
<span class="label">
<xsl:value-of select="concat($label, ' : ')"/>
</span>
<span class="value">
<xsl:value-of select="."/>
</span>
<br/>
</xsl:template>
</xsl:stylesheet>
When applied to the following XML:
<Member TextRank="unknown" ID="12" FullName="My Name" Dob="01/01/1970" />
The following is output:
<div class="Member">
<div> Title: </div>
<span class="label">TextRank : </span>
<span class="value">unknown</span>
<br>
<span class="label">ID : </span>
<span class="value">12</span>
<br>
<span class="label">Full Name : </span>
<span class="value">My Name</span>
<br>
<span class="label">Dob : </span>
<span class="value">01/01/1970</span>
<br>
</div>

This is the solution I came up with.
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output indent="yes" />
<xsl:template match="*">
<xsl:element name="div">
<xsl:attribute name="class">className</xsl:attribute>
<div>
Title:
</div>
<!-- UID, Name, DBO-->
<xsl:apply-templates select="#ID"/>
<xsl:apply-templates select="#FullName"/>
<xsl:apply-templates select="#Dob"/>
</xsl:element>
</xsl:template>
<xsl:template match="#*">
<xsl:element name="span">
<xsl:attribute name="class">label</xsl:attribute>
<xsl:choose>
<xsl:when test="name() = 'FullName'">
Full Name
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="name()"/>
</xsl:otherwise>
</xsl:choose>
:
</xsl:element>
<xsl:element name="span">
<xsl:attribute name="class">value</xsl:attribute>
<xsl:value-of select="."/>
</xsl:element>
<br/>
</xsl:template>
</xsl:stylesheet>

Extreme XSLT XML Flattening

I have the following input XML file:
<root>
<a>
<b>1</b>
</a>
<c>
<d>
<e>2</e>
<f>3</f> or <e>3</e>
</d>
<g h="4"/>
<i>
<j>
<k>
<l m="5" n="6" o="7" />
<l m="8" n="9" o="0" />
</k>
</j>
</i>
</c>
</root>
I would like to use XSLT to transform it into the follow outputs:
OUTPUT 1
<root>
<row b="1" e="2" f="3" h="4" m="5" n="6" o="7" />
<row b="1" e="2" f="3" h="4" m="8" n="9" o="0" />
<root>
OUTPUT 2
<root>
<row b="1" e="2" h="4" m="5" n="6" o="7" />
<row b="1" e="2" h="4" m="8" n="9" o="0" />
<row b="1" e="3" h="4" m="5" n="6" o="7" />
<row b="1" e="3" h="4" m="8" n="9" o="0" />
<root>
Can anyone help my XSLT isn't very strong. Thanks.

It will be easier if you let the occurrence of <e> determine the outer loop constructing your <row>s and have a inner loop iterating over all <l>s.
Try something like this:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:apply-templates />
</xsl:template>
<xsl:template match="root">
<root>
<xsl:apply-templates />
</root>
</xsl:template>
<xsl:template match="e">
<!-- store values of 'e' and 'f' in params -->
<xsl:param name="value_of_e" select="." />
<xsl:param name="value_of_f" select="ancestor::d[1]/f" />
<!-- iterate over all 'l's -->
<xsl:for-each select="//l">
<xsl:element name="row">
<xsl:attribute name="b">
<xsl:value-of select="//b" />
</xsl:attribute>
<xsl:attribute name="e">
<xsl:value-of select="$value_of_e" />
</xsl:attribute>
<!-- only include 'f' if it has a value -->
<xsl:if test="$value_of_f != ''">
<xsl:attribute name="f">
<xsl:value-of select="$value_of_f" />
</xsl:attribute>
</xsl:if>
<xsl:attribute name="h">
<xsl:value-of select="ancestor::c[1]/g/#h" />
</xsl:attribute>
<xsl:attribute name="m">
<xsl:value-of select="./#m" />
</xsl:attribute>
<xsl:attribute name="n">
<xsl:value-of select="./#n" />
</xsl:attribute>
<xsl:attribute name="o">
<xsl:value-of select="./#o" />
</xsl:attribute>
</xsl:element>
</xsl:for-each>
</xsl:template>
<xsl:template match="b" />
<xsl:template match="f" />
<xsl:template match="g" />
</xsl:stylesheet>

Sorting a nodeset before passing to xsl:for-each

I have a situation where loop through a sorted nodeset and apply a template on each of the nodes:
<div id="contractscontainer">
<xsl:for-each select="document">
<xsl:sort select="content[#name='ClientName']/text()" />
<xsl:apply-templates select="." mode="client-contract" />
</xsl:for-each>
</div>
I want to do something special with the "first" 5 nodes in the node set and render them nested element. The problem is that they need to be in the same order as if they were sorted (as they are in the loop).
I had planned on doing this by using two xsl:for-each elements, each with the correct nodes selected from the set. I can't do this, however, because they need to be sorted before I can select the "first" 5.
Example:
<div id="contractscontainer">
<div class="first-five">
<xsl:for-each select="document[position() < 6]">
<xsl:sort select="content[#name='ClientName']/text()" />
<xsl:apply-templates select="." mode="client-contract" />
</xsl:for-each>
</div>
<div class="rest-of-them">
<xsl:for-each select="document[position() > 5]">
<xsl:sort select="content[#name='ClientName']/text()" />
<xsl:apply-templates select="." mode="client-contract" />
</xsl:for-each>
</div>
</div>
I don't think this will work because I'm selecting the nodes by position before sorting them, but I can't use xsl:sort outside of the xsl:for-each.
Am I approaching this incorrectly?
Edit: My current solution is to sort them and store the sorted set in another variable:
<xsl:variable name="sorted-docs">
<xsl:for-each select="document">
<xsl:sort select="content[#name='ClientName']/text()" />
<xsl:copy-of select="." />
</xsl:for-each>
</xsl:variable>
It works, but is there a better way?

Here is one way to do this in XSLT 1.0 without the need to use the xxx:node-set() extension function:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/*">
<html>
<div class="first-five">
<xsl:apply-templates select="num">
<xsl:sort select="." data-type="number"/>
<xsl:with-param name="pStart" select="1"/>
<xsl:with-param name="pEnd" select="5"/>
</xsl:apply-templates>
</div>
<div class="rest-of-them">
<xsl:apply-templates select="num">
<xsl:sort select="." data-type="number"/>
<xsl:with-param name="pStart" select="6"/>
</xsl:apply-templates>
</div>
</html>
</xsl:template>
<xsl:template match="num">
<xsl:param name="pStart"/>
<xsl:param name="pEnd" select="999999999999"/>
<xsl:if test="position() >= $pStart
