loop through static list of values?

mister_mister · January 3rd, 2008, 04:02 PM

in xslt 1.0, using the following list of medical specialties below, how can i loop through this list and pass each specialty to a call-template function?

Allergy & Immunology
Anesthesiology
Behavioral Health
Cardiology

ive googled my question to some extent without any luck. the solutions ive found use tokenize() with a comma separated string variable, but this only works in xslt 2.0. is there a solution for xslt 1.0 that would solve my problem?

thanks in advance,
steve

In XSLT 1.0 if you have structured data it's best to mark it up as XML, that is

<specialities>
<speciality>Allergy & Immunology</speciality>
<speciality>Anesthesiology</speciality>
etc.

It's then easy to iterate over the list using path expressions, xsl:for-each, etc.

If you need to get it into this form by parsing text, there is always the str:tokenize template at www.exslt.org

in my XSLT, when i put the list of specialties into XML format, it ends up just outputing the specialties as text on my webpage. i already have an XML document (from a CMS) supplying my XSLT with all the data. i need to be able to use my static list of specialties from within my XSLT do accomplish the following (doesn't work):

Code:


<xsl:for-each select="specialties/specialty">
  <xsl:variable name="currentSpecialty" select="." />
  <xsl:if test="Collection/Hits/Content[Html/root/Specialty=$currentSpecialty]">
    <xsl:call-template name="specialtyHeader">
      <xsl:with-param name="specialtyHeader" select="$currentSpecialty" />
    </xsl:call-template>
    <xsl:for-each select="Collection/Hits/Content[Html/root/Specialty=$currentSpecialty]">
      <xsl:sort select="Html/root/SVRMCPhysician" order="descending" />
      <xsl:sort select="Html/root/LastName" order="ascending" />
      <xsl:call-template name="display"></xsl:call-template>
    </xsl:for-each>
  </xsl:if> 
</xsl:for-each>

i download the str:tokenize zip package from www.exslt.org and tried to make it work to no avail. it was way over my head :)

any help is greatly appreciated.

Once you are inside the first for-each loop your context changes, so the next one should either refer to a previously defined variable, or back to the the root node I suspect:

<xsl:if test="/Condition/...">

or

<xsl:if test="$Condition/...">

Oh, and add a simple template so your data isn't output, e.g.:

<xsl:template match="specialities"></xsl:template>

i tried storing my condition in a variable, but it didn't work.

it might help if i just posted my exact code below. what im really trying to do is simply just loop through a static list of values (each specialty):

my XML:

Code:

<Collection>
  <Hits count="1">
    <HitsMarker>*</HitsMarker>
    <Content>
      <Hits>1</Hits>
      <ID>5704</ID>
      <Title>Smith, Jane</Title>
      <QuickLink>/index.aspx?id=5704</QuickLink>
      <Teaser>
        <p>Allergy &amp; Immunology Anesthesiology Jane Smith Female No Select a State</p>
      </Teaser>
      <Html>
        <root>
          <Specialty>Allergy &amp; Immunology</Specialty>
          <Specialty>Anesthesiology</Specialty>
          <FirstName>Jane</FirstName>
          <LastName>Smith</LastName>
          <Gender>Female</Gender>
          <SVRMCPhysician>No</SVRMCPhysician>
          <Photo></Photo>
          <AddressLine1 />
          <AddressLine2 />
          <City />
          <State></State>
          <Zip />
          <Phone />
          <Fax />
          <Website />
          <PhysicianInformation></PhysicianInformation>
        </root>
      </Html>
    </Content>
    <Content>
      ...etc...
    </Content>
    <Content>
      ...etc...

  </Hits>

my XSLT

</xsl:stylesheet>

im sure there's many other things wrong with what ive done in my code above, but im new to XSLT. does anyone know how i would loop through my static list of specialties?

thanks in advance,
steve

If you want to put data into your XSLT stylesheet then you can do so but you need to use a top-level element (child of the root element) and put your data element into a namespace. Then you can use document('') to access the data in the stylesheet e.g.

Code:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:dt="http://example.com/2008/mydata"
  exclude-result-prefixes="dt"
  version="1.0">

  <data xmlns="http://example.com/2008/mydata">
    <AllSpecialties xmlns="">
      <Specialty>Allergy &amp; Immunology</Specialty>
      <Specialty>Anesthesiology</Specialty>
      <Specialty>Behavioral Health Services</Specialty>
      <Specialty>Birthing &amp; Womens Services</Specialty>
      <Specialty>...etc...</Specialty>
    </AllSpecialties>
  </data>

  <xsl:variable name="sp"
            select="document('')/*/dt:data/AllSpecialties/Specialty"/>
