Apply multiple xsl match template on a xml
Hi friends, I'm new to XML/XSLT...can you help as usual please
Scenario is, I have several xml files where I need to remove certain sections based on the value I specify. Basically to appply multiple xslt templates on a XML document.
please check the attached sample xml and below xslt document (I couldnt attach it)
sample.xml: contains 4 sections.
testone.xslt: Has got one template to remove "First" section. this works fine.
testtwo.xslt: Has got two templates to remove "First" and "Third" section. this isnt working as expected.
I was trying to apply multiple templates on a single document in one go.
thanks in advance.

sample.xml
// Get All filenames. In the example
string MyXmlPath = Request.PhysicalApplicatio
// Xslt
string MyXsltPath = Request.PhysicalApplicatio
// Now create an instance of the XPathDocument class and store in there the XML document
XPathDocument xmlDoc = new XPathDocument(MyXmlPath);
// Now create an instance of the XslCompiledTransform class that we will use to transform the XML data using an XSLT stylesheet
XslCompiledTransform XSLTransform = new XslCompiledTransform();
XSLTransform.Load(MyXsltPa
// Then execute the transform and output the results.
XSLTransform.Transform(MyX
Do not forget to add these namespaces in the Default.aspx.cs file
using System.Xml;
using System.Xml.Xsl;
using System.Xml.XPath;
Run your application and see the MyXmlData's related data (transformed by the XLST file) being displayed in the screen.
If you want the transformation results to be saved to an .htm file you must ,
1. comment out this line of code
// XSLTransform.Transform(MyX
2. Add another item to your site, an .htm file. Name it MyHtmlPage.htm.
iii) Add these lines of code to the Page_Load routine.
string MyHTMLPath = Request.PhysicalApplicatio
XSLTransform.Transform(MyX
Run your application and see the MyXmlData's related data (transformed by the XLST file) being written into the html file.Open the MyHtmlPage.htm file
string MyXmlPath = Request.PhysicalApplicatio
// Xslt
string MyXsltPath = Request.PhysicalApplicatio
// Now create an instance of the XPathDocument class and store in there the XML document
XPathDocument xmlDoc = new XPathDocument(MyXmlPath);
// Now create an instance of the XslCompiledTransform class that we will use to transform the XML data using an XSLT stylesheet

thanks pravin for helping out. unfortunately, I'm not a .net or java person and I cannot use those. sorry.
I was using below online xslt tester to get my result. Later I might integrate with ANT and/or vbscript (when using vbscript I was using microsoft command line util "msxsl.exe")

please help if you can

Hi enthuguy,
Sorry for not paying attention to this question earlier.
I will object to the deletion and explain what you are doing wrong.
I hope it is still relevant to you, I only saw this now.
If it is no longer relevant... ignore my response and continue deletion, no problem with that
Geert

Here is the problem
<xsl:template match="ns1:ListOfFields/ns
...
You have two templates with the same match.
This is not allowed, and two can not be active at the same time
The last one will be picked and depending on the processor, you will get a warning or an error
the trick is to be more specific in the template itself
meaning that the best practice in XSLT is to have three templates in this case (and drop the choose construct)
first template
second template
The empty template will delete these nodes
A third template should serve as a fallback for cases that don't apply to the condition
You don't need a specific template for these "otherwise", since these will be picked up by the generic identity copy you already have
If no longer relevant, I hope you learn something from this
Alternatively you can have 1 template and two when clauses in a big choose...
but what I propose is commonly considered best practice
So, you should
-always avoid choose constructs in favour of multiple templates with a predicate in the match
- never have two templates matching the same node with equal preference and equal mode
cheers
