Consider this Directory,
<Directory Id="MyProgramDir" Name="DirName">
<Component Id="comp_MyProgramDir" Guid="FC0409CE-27E6-475E-B6C2-95E4B4C0223C" KeyPath="yes">
<Condition><![CDATA[MyCondition]]></Condition>
</Component>
</Directory>
I have to apply MyCondition to all children components of the Directory. Since it is a very big Directory containing many files, is there a way to avoid to write the condition for every component? The Transitive attribute is not helpful at all!
You can try this:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:wix="http://schemas.microsoft.com/wix/2006/wi">
<xsl:output method="xml" indent="yes" cdata-section-elements="wix:Condition"/>
<xsl:strip-space elements="*" />
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="wix:Component">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
<xsl:element name="Condition" namespace="http://schemas.microsoft.com/wix/2006/wi">
<xsl:attribute name="level">1</xsl:attribute>
<xsl:text>MyCondition</xsl:text>
</xsl:element>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

I am trying to create an empty file through xslt.
The input sample is:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Businessman>
<siblings>
<sibling>John </sibling>
</siblings>
<child> Pete </child>
<child> Ken </child>
</Businessman>
When the input contains any presence of 'child' tags, it should produce the file AS IS. When the input does not have any 'child' tag, I need an empty file (0 byte file) created.
This is what I tried:
<?xml version="1.0" encoding="UTF-8"?>
<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="#*|node()">
<xsl:choose>
<xsl:when test="/Businessman/child">
<xsl:copy>
<xsl:apply-templates select="#*|node()" />
</xsl:copy>
</xsl:when>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
This gives the file unchanged when there is any 'child' tag present. But did not produce any empty file when there is no 'child' tag.
The file I need to test will look like:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Businessman>
<siblings>
<sibling>John </sibling>
</siblings>
</Businessman>
Any help would be great!
Thanks
If you want the processor to go to the trouble of opening the output file, you have to give it something to write to the output file. Try an empty text node. And you only need to make the decision 'copy or not?' once.
One way to make the decision just once and produce empty output if the condition is not met would be to replace your template with:
<xsl:template match="/">
<xsl:choose>
<xsl:when test="/Businessman/child">
<xsl:copy-of select="*"/>
</xsl:when>
<xsl:otherwise>
<xsl:text/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
This works as expected with xsltproc. (If you find yourself getting a file containing an XML declaration and nothing else, try adjusting the parameters on xsl:output.)
But when I have found myself with a similar situation (perform this transform if condition C holds, otherwise ...), I have simply added a template for the document node that would look something like this for your case:
<xsl:choose>
<xsl:when test="/Businessman/child">
<xsl:apply-templates/>
</
<xsl:otherwise>
<xsl:message terminate="yes">No children in this input, dying ...</
</
</
That way I get no output at all rather than zero-length output.
Simple enough - Just don't try to do everything in one template, don't forget to omit the xml declaration and get the xpath right:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />
<xsl:template match="/">
<xsl:apply-templates />
</xsl:template>
<xsl:template match="Businessman[child]" priority="9">
<xsl:element name="Businessman">
<xsl:apply-templates />
</xsl:element>
</xsl:template>
<xsl:template match="Businessman" priority="0" />
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
I have an XML document (generated by WiX heat) where I want to remove the root element name while removing the attribute. The source tree looks like this
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
<Fragment>
<DirectoryRef Id="HELP" />
</Fragment>
</Wix>
I figured out how to rename the node, but this doesn't remove the unnecessary attribute xmlns.
<xsl:template match='/wix:Wix'>
<Include>
<xsl:copy-of select="#*|node()"/>
</Include>
</xsl:template>
<!-- Even this template doesn't suppress the attribute xmlns -->
<xsl:template match='#xmlns'/>
I event removed the #*| from the select clause. But this doesn't have any effect.
How can I produce with XSLT 1.0 the following desired output?
<Include>
<Fragment>
<DirectoryRef Id="HELP" />
</Fragment>
</Include>
this doesn't remove the unnecessary attribute xmlns.
xmlnsis not an attribute - it's a namespace, a part of the node's name. If you don't want it in the output, you cannot copy the input nodes that are in a namespace - you must create new nodes instead, for example:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:wix="http://schemas.microsoft.com/wix/2006/wi"
exclude-result-prefixes="wix">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/wix:Wix">
<Include>
<xsl:apply-templates/>
</Include>
</xsl:template>
<xsl:template match="*">
<xsl:element name="{local-name()}">
<xsl:copy-of select="#*"/>
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
I am unaware of XSLT,Please help:
I have the following XML:
<OLifE>
<Holding id="1234">
<HoldingKey>1397650618090</HoldingKey>
<HoldingTypeCode tc="2">Policy</HoldingTypeCode>
<HoldingStatus tc="2">Inactive</HoldingStatus>
<CarrierAdminSystem>PAS</CarrierAdminSystem>
</Holding>
</OLifE>
I want the output like this:
<OLifE>
<Holding>
<id>1234</id>
<HoldingKey>1397650618090</HoldingKey>
<HoldingTypeCode>
<tc>2</tc>
<value>Policy</value>
</HoldingTypeCode>
<HoldingStatus>
<tc>2</tc>
<value>Inactive</value>
</HoldingStatus>
<CarrierAdminSystem>PAS</CarrierAdminSystem>
</Holding>
</OLifE>
please note that, all attributes are needed to be converted to child elements but, for elements that have a tc attribute specified:
<HoldingTypeCode tc="2">Policy</HoldingTypeCode>
need to be handled carefully.
I DO NOT want the output like:
<HoldingTypeCode>
<tc>2</tc>Policy</HoldingTypeCode>
I have the following XSLT code which needs the slight modification:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml"/>
<xsl:template match="*">
<xsl:element name="{name()}">
<xsl:for-each select="#*">
<xsl:element name="{name()}">
<xsl:value-of select="."/>
</xsl:element>
</xsl:for-each>
<xsl:apply-templates select="*|text()"/>
</xsl:element>
</xsl:template>
Please help.
Assuming you want a generic solution, how about:
XSLT 1.0
<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:strip-space elements="*"/>
<!-- modified identity transform -->
<xsl:template match="node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
<!-- attributes to elements -->
<xsl:template match="#*">
<xsl:element name="{name()}">
<xsl:value-of select="."/>
</xsl:element>
</xsl:template>
<!-- avoid mixed content -->
<xsl:template match="text()[../#*]">
<value>
<xsl:value-of select="."/>
</value>
</xsl:template>
</xsl:stylesheet>
Edit
However, the root element in my original XML has got xmlns="some web
address" attribute.
In such case, change the first template to:
<!-- modified identity transform -->
<xsl:template match="*">
<xsl:element name="{name()}">
<xsl:apply-templates select="#* | node()"/>
</xsl:element>
</xsl:template>
This is assuming you want all the output nodes to be in no namespace.
I think you can define a template like this to be called where you want to output the attributes :
<xsl:template name="transform.attrs">
<xsl:for-each select="#*">
<xsl:element name="{name()}">
<xsl:value-of select="."/>
</xsl:element>
</xsl:for-each>
</xsl:template>
For the most general case you use almost the same template as before, just call the new template for attributes:
<xsl:template match="*">
<xsl:element name="{name()}">
<xsl:call-template name="transform.attrs">
<xsl:apply-templates select="*|text()"/>
</xsl:element>
</xsl:template>
And for the specific elements, bearing the #tc attribute:
<xsl:template match="*[#tc]">
<xsl:element name="{name()}">
<xsl:call-template name="transform.attrs" />
<value>
<xsl:apply-templates select="*|text()"/>
</value>
</xsl:element>
</xsl:template>
I have the source collection as below.
<SourceCollection>
<Row1>
<Col1>Store1</Col1>
<Col2>Med1</Col2>
<Col3>Val1</Col3>
</Row1>
<Row2>
<Col1>Store1</Col1>
<Col2>Med1</Col2>
<Col3>Val2</Col3>
</Row2>
<Row3>
<Col1>Store1</Col1>
<Col2>Med2</Col2>
<Col3>Val2</Col3>
</Row3>
<Row4>
<Col1>Store2</Col1>
<Col2>Med1</Col2>
<Col3>Val4</Col3>
</Row4>
</SourceCollection>
I want the target collection as below with minimal usage of for each.
<TargetCollection>
<Store value=Store1>
<Dim value=Med1>
<DimCode>Val1</DimCode>
<DimCode>Val2</DimCode>
</Dim>
<Dim value=Med2>
<DimCode>Val3</DimCode>
</Dim>
</Store>
<Store value=Store2>
<Dim value=Med1>
<DimCode>Val4</DimCode>
</Dim>
</Store>
</TargetCollection> `
In my initial design I used 3 for-each loops on the same source collection to form the target xml as required. But,the source collection contains millions of rows, which is making my transformation to traverse the whole list (Rows)to the power of 3 times, which is hitting the system performance.
Please let me know any ideas to avoid this.
Generally, using xsl:key can help speed up transforms. Try something like this:
<?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:key name="Col1" match="Col1" use="."/>
<xsl:key name="Col2byCol1" match="Col2" use="concat(../Col1, '-', .)"/>
<xsl:key name="Col3byCol1andCol2"
match="Col3" use="concat(../Col1, '-', ../Col2, '-', .)"/>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="SourceCollection">
<TargetCollection>
<xsl:apply-templates
select="*/Col1[generate-id() =
generate-id(key(local-name(), .)[1])]"/>
</TargetCollection>
</xsl:template>
<xsl:template match="Col1">
<xsl:variable name="Column1" select="."/>
<Store value="{.}">
<xsl:apply-templates select="../../*/Col2[generate-id() =
generate-id(key('Col2byCol1', concat($Column1, '-' ,.))[1])]"/>
</Store>
</xsl:template>
<xsl:template match="Col2">
<xsl:variable name="Column1" select="../Col1"/>
<xsl:variable name="Column2" select="."/>
<Dim value="{.}">
<xsl:apply-templates
select="../../*[Col2=$Column2]/Col3[generate-id() =
generate-id(key('Col3byCol1andCol2',
concat($Column1, '-', $Column2, '-',.)))]"/>
</Dim>
</xsl:template>
<xsl:template match="Col3">
<DimCode value="{.}">
<xsl:apply-templates />
</DimCode>
</xsl:template>
</xsl:stylesheet>
I am harvesting a directory using heat, however, I couldnt find an option to set the "ReadOnly" attributes for all files harvest using heat.
Does anyone have know any way of doing it in heat?
Apply an XSLT transform to the fragment generated by heat and add ReadOnly="yes" to every File element. This XSLT does the thing:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://schemas.microsoft.com/wix/2006/wi"
xmlns:wix="http://schemas.microsoft.com/wix/2006/wi">
<xsl:template match="wix:File">
<xsl:copy>
<xsl:apply-templates select="#*" />
<xsl:attribute name="ReadOnly">
<xsl:text>yes</xsl:text>
</xsl:attribute>
<xsl:apply-templates select="*" />
</xsl:copy>
</xsl:template>
<xsl:template match="*">
<xsl:copy>
<xsl:apply-templates select="#*" />
<xsl:apply-templates select="* | text()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="#* | text()">
<xsl:copy />
</xsl:template>
<xsl:template match="/">
<xsl:apply-templates />
</xsl:template>
</xsl:stylesheet>
