I have the following XML
<?xml version="1.0" encoding="ISO-8859-1" ?>
- <DEVICEMESSAGES>
<VERSION xml="1" checksum="" revision="0" envision="33050000" device="" />
<HEADER id1="0001" id2="0001" content="Nasher[<messageid>]: <!payload>" />
<MESSAGE level="7" parse="1" parsedefvalue="1" tableid="15" id1="24682" id2="24682" eventcategory="1003010000" content="Access to <webpage> was blocked due to its category (<info> by <hostname>)" />
</DEVICEMESSAGES>
I am using the following xslt
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:strip-space elements="*"/>
<xsl:template match="DEVICEMESSAGES">
<xsl:value-of select="#id2"/>,<xsl:text/>
<xsl:value-of select="#content"/>,<xsl:text/>
<xsl:text>
</xsl:text>
</xsl:template>
</xsl:stylesheet>
when i use MSXML i just get ,, whereas i want to have something like
id2, content
0001 , Nasher[<messageid>]: <!payload>"
The DEVICEMESSAGES element doesn't have attributes at all.
Change:
<xsl:template match="DEVICEMESSAGES">
to:
<xsl:template match="DEVICEMESSAGES/HEADER">

I am trying to remove Error Description element if it contains empty value using xslt. i tried lot of options but it does not work.
For example if inside Acknowledgement all the element get null then output get empty acknowledgement so I want remove acknowledgement element empty tag.
below is xml and xslt
<?xml version="1.0" encoding="UTF-8" ?>
<updateDocumentStatusResponse xmlns="http://xmlns.be/CommgrService_Message/v001">
<Acknowledgement>
<Result>SUCCESS</Result>
<ErrorCode>ErrorCode1375</ErrorCode>
<ErrorDescription></ErrorDescription>
</Acknowledgement>
</updateDocumentStatusResponse>

how can i achieve this?
I think this can be done if you're not thinking something big:
<xsl:if test="normalize-space(/ns0:updateDocumentStatusResponse/ns0:Acknowledgement/ns0:ErrorDescription) != ''">
<ns1:ErrorDescription>
<xsl:value-of select="/ns0:updateDocumentStatusResponse/ns0:Acknowledgement/ns0:ErrorDescription"/>
</ns1:ErrorDescription>
</xsl:if>
Edit:
One way to achieve this using extension function like exsl:node-set or msxsl:node-set to be able to further process a result tree fragment created in another template:

If you take a top-down aproach with literal result elements you are always going to get that element in the output. Your only choice then is to chain two transformations or use a two pass transformation.
The XPath expression to know whether the current node is empty (true) or not (false) is:
"not(node())"
For example, this input document
<?xml version="1.0" encoding="UTF-8" ?>
<updateDocumentStatusResponse xmlns="http://xmlns.be/CommgrService_Message/v001">
<Acknowledgement>
<Result>SUCCESS</Result>
<ErrorCode>ErrorCode1375</ErrorCode>
<ErrorDescription></ErrorDescription>
</Acknowledgement>
</updateDocumentStatusResponse>
With this transformation
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:strip-space elements ="*"/>
<xsl:output indent="yes"/>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[not(node())]"/>
</xsl:stylesheet>
Output
<updateDocumentStatusResponse xmlns="http://xmlns.be/CommgrService_Message/v001">
<Acknowledgement>
<Result>SUCCESS</Result>
<ErrorCode>ErrorCode1375</ErrorCode>
</Acknowledgement>
</updateDocumentStatusResponse>
Edit
The previus stylesheet is general. If you want to target specific elements, you need to match those elements with the pattern in the template. Example:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:strip-space elements ="*"/>
<xsl:output indent="yes"/>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="ErrorDescription[not(node())]"/>
</xsl:stylesheet>
Environment: XSLT 1.0
The transform will take each element in partOne section and lookup #field attribute in partTwo section using #find attribute and then output #value attribute.
I'm using a for-each loop and was wondering if apply-templates could work?
xml
<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="file.xslt"?>
<xml>
<partOne>
<target field="hello"/>
<target field="world"/>
</partOne>
<partTwo>
<number input="2" find="hello" value="valone" />
<number input="2" find="world" value="valtwo" />
<number input="2" find="hello" value="valthree" />
<number input="2" find="world" value="valfour" />
</partTwo>
</xml>
xsl
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="text"/>
<xsl:template match="/">
<xsl:apply-templates />
</xsl:template>
<xsl:template match="/xml/partOne/target">
,<xsl:value-of select="#field"/>
<xsl:for-each select="/xml/partTwo/number[#find=current()/#field]">
,<xsl:value-of select="#value"/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Output:
,hello
,valone
,valthree
,world
,valtwo
,valfour
Well, it seems straight-forward to change
<xsl:for-each select="/xml/partTwo/number[#find=current()/#field]">
,<xsl:value-of select="#value"/>
</xsl:for-each>
to
<xsl:apply-templates select="/xml/partTwo/number[#find=current()/#field]"/>
with a template
<xsl:template match="partTwo/number">
,<xsl:value-of select="#value"/>
</xsl:template>
As your root template so far processes all elements you need to change it to
<xsl:template match="/">
<xsl:apply-templates select="xml/partOne"/>
</xsl:template>
to avoid processing the partTwo element(s) twice.
For the cross-reference you might want to use a key in both versions:
<xsl:key name="ref" match="partTwo/number" use="#find"/>
and then select="key('ref', #field)" instead of select="/xml/partTwo/number[#find=current()/#field]" for the apply-templates or for-each.
Seeking advice on how to calculate the lowerCorner and upperCorner in GML Envelope given an array (coordinates) in the XML. Note I have reduced the list of coordinates significantly to keep short.
Aware I need to iterate the <coordinates> element but unsure most efficient way to calculate the lowerCorner and upperCorner pairs to eventually map into the GML Envelope.

Assuming you want to find the coordinates of the rectangle bounding your polygon, and assuming your processor supports the EXSLT extension functions str:split(), math:min() and math:max() (IOW, you are using either libxslt or Xalan), you could do something like:
XSLT 1.0 + EXSLT
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:n1="urn:com:aaa"
xmlns:exsl="http://exslt.org/common"
xmlns:math="http://exslt.org/math"
xmlns:str="http://exslt.org/strings"
extension-element-prefixes="exsl math str"
exclude-result-prefixes="n1">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/Extract">
<xsl:variable name="vertices-rtl">
<xsl:for-each select="str:split(n1:XMLExtract/coordinates, ', ')">
<v x="{substring-before(., ' ')}" y="{substring-after(., ' ')}"/>
</xsl:for-each>
</xsl:variable>
<xsl:variable name="vertices" select="exsl:node-set($vertices-rtl)/v" />
<output>
<lowerLeft>
<xsl:value-of select="math:min($vertices/#x)" />
<xsl:text> </xsl:text>
<xsl:value-of select="math:min($vertices/#y)" />
</lowerLeft>
<upperRight>
<xsl:value-of select="math:max($vertices/#x)" />
<xsl:text> </xsl:text>
<xsl:value-of select="math:max($vertices/#y)" />
</upperRight>
</output>
</xsl:template>
</xsl:stylesheet>
Applied to your example input, the result will be:
<?xml version="1.0" encoding="UTF-8"?>
<output>
<lowerLeft>151.344553 -33.4199650000193</lowerLeft>
<upperRight>151.39785 -33.3990000000192</upperRight>
</output>
I have the following xml:
<RootNode xmlns="http://someurl/path/path/path">
<Child1>
<GrandChild1>Value</GrandChild1>
<!-- Lots more elements in here-->
</Child1>
</RootNode>
I have the following xslt:
<xsl:stylesheet version="1.0" xmlns="http://someurl/path/path/path" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<NewRootNode xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<NewChild1>
<xsl:for-each select="RootNode/Child1">
<NewNodeNameHere>
<xsl:value-of select="GrandChild1"/>
</NewNodeNameHere>
<!-- lots of value-of tags in here -->
</xsl:for-each>
</NewChild1>
</NewRootNode >
</xsl:template>
</xsl:stylesheet>
The problem: this is the my result:
<?xml version="1.0" encoding="utf-8"?>
<NewRootNode xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<NewChild1 />
</NewRootNode>
I am expecting to see:
<?xml version="1.0" encoding="utf-8"?>
<NewRootNode xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<NewChild1>
<NewNodeNameHere>Value</NewNodeNameHere>
<!-- Other new elements with values from the xml file -->
</NewChild1>
</NewRootNode>
I am missing of the information inside of NewChild1 that should be there.
I think my for-each select is correct, so the only thing I can think of is that there is a problem with the namespace in the Xml and the namespace in the xslt. Can anybody see what I'm doing wrong?
The problem is caused by the namespaces.
Since the xml defines xmlns="http://someurl/path/path/path", it is not in the default namespace anymore.
You can define that namespace with an name like xmlns:ns="http://someurl/path/path/path" in the xsl, and then use that name in the XPath expression.
The following works for me:
<xsl:stylesheet version="1.0" xmlns:ns="http://someurl/path/path/path" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<NewRootNode xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<NewChild1>
<xsl:for-each select="ns:RootNode/ns:Child1">
<NewNodeNameHere>
<xsl:value-of select="ns:GrandChild1"/>
</NewNodeNameHere>
<!-- lots of value-of tags in here -->
</xsl:for-each>
</NewChild1>
</NewRootNode >
</xsl:template>
</xsl:stylesheet>
The stylesheet namespace should be http://www.w3.org/1999/XSL/Transform instead of http://someurl/path/path/path.
Also, since the input XML uses a namespace all your XPath expressions should be namespace-qualified:
<xsl:template match="/" xmlns:ns1="http://someurl/path/path/path">
<NewRootNode xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<NewChild1>
<xsl:for-each select="ns1:RootNode/ns1:Child1">
<NewNodeNameHere>
<xsl:value-of select="ns1:GrandChild1"/>
</NewNodeNameHere>
<!-- lots of value-of tags in here -->
</xsl:for-each>
</NewChild1>
</NewRootNode>
</xsl:template>
I wanted to use a dynamic variable name in the select statement in xslt.
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<xsl:variable name="input" select="input/message" />
<xsl:variable name="Name" select="'MyName'" />
<xsl:variable name="Address" select="MyAddress" />
<xsl:variable name="output" select="concat('$','$input')" /> <!-- This is not working -->
<output>
<xsl:value-of select="$output" />
</output>
</xsl:template>
The possible values for the variable "input" is 'Name' or 'Address'.
The select statement of the output variable should have a dynamic variable name based on the value of input variable. I don't want to use xsl:choose. I wanted to select the value dynamically.
Please provide me a solution.
Thanks,
dhinu
XSLT 1.0 and XSLT 2.0 don't have dynamic evaluation.
Solution for your problem:
This transformation:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:my="my:my">
<xsl:output method="text"/>
<my:values>
<name>MyName</name>
<address>MyAdress</address>
</my:values>
<xsl:template match="/">
<xsl:variable name="vSelector"
select="input/message"/>
<xsl:value-of select=
"document('')/*/my:values/*[name()=$vSelector]"/>
</xsl:template>
</xsl:stylesheet>
when applied on the following XML document:
<input>
<message>address</message>
</input>
produces the wanted, correct result:
MyAdress
when the same transformation is applied on this XML document:
<input>
<message>name</message>
</input>
again the wanted, correct result is produced:
MyName
Finally: If you do not wish to use the document() function, but would go for using the xxx:node-set() extension function, then this solution (looking very similar) is what you want, where you may consult your XSLTprocessor documentation for the exact namespace of the extension:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ext="http://exslt.org/common" >
<xsl:output method="text"/>
<xsl:variable name="vValues">
<name>MyName</name>
<address>MyAdress</address>
</xsl:variable>
<xsl:template match="/">
<xsl:variable name="vSelector"
select="input/message"/>
<xsl:value-of select=
"ext:node-set($vValues)/*[name()=$vSelector]"/>
</xsl:template>
</xsl:stylesheet>
Beside #Dimitre's good answer, for this particular case (output string value) you could also use:
<xsl:variable name="output"
select="concat(substring($Name, 1 div ($input = 'Name')),
substring($Address, 1 div ($input = 'Address')))"/>
