I need to remove some unwanted fields over a big response XML using XSL 1.0, and want to use apply-templates instead of for-each. Below is the code I tried but is not giving expected results i.e., unwanted fields are removed successfully but few other fields outside match also disappeared. Am I using identity template incorrectly.
Input XML:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:object xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:array name="BankDetails">
<one>field1</one>
<two>field2</two>
<xsl:object>
<date>1234-56-78</date>
<Time>12345678</Time>
</xsl:object>
<xsl:object>
<date>0000-00-00</date>
<Time>00000000</Time>
</xsl:object>
<xsl:object>
<date>0000-00-00</date>
<Time>00000000</Time>
</xsl:object>
<xsl:object>
<date>0000-00-00</date>
<Time>00000000</Time>
</xsl:object>
<three>field3</three>
<four>field4</four>
<five>field5</five>
<six>field6</six>
</xsl:array>
</xsl:object>
Applied XSLT:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:axsl="http://www.w3.org/1999/XSL/TransformAlias"
xmlns:str="http://exslt.org/strings">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" />
<xsl:namespace-alias stylesheet-prefix="axsl" result-prefix="xsl" />
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="xsl:object/xsl:array">
<xsl:for-each select="xsl:object[Time !='00000000']">
<xsl:copy-of select = "."/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
What I got:
<?xml version="1.0" encoding="UTF-8"?><xsl:object xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:object>
<date>1234-56-78</date>
<Time>12345678</Time>
</xsl:object>
</xsl:object>
What is expected:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:object xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:array name="BankDetails">
<one>field1</one>
<two>field2</two>
<xsl:object>
<date>1234-56-78</date>
<Time>12345678</Time>
</xsl:object>
<three>field3</three>
<four>field4</four>
<five>field5</five>
<six>field6</six>
</xsl:array>
</xsl:object>
The problem with your attempt is that you are copying only xsl:object
elements that have the right Time
- but not doing anything (i.e. copy or apply templates) for the other elements that are also children of the context xsl:array
element (one
, two
etc). If you do not apply templates to them, then the identity transform template will not be applied to them.
You are also not copying the context xsl:array
element.
I would suggest you approach it from the opposite point-of-view:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:axsl="http://www.w3.org/1999/XSL/TransformAlias">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" />
<xsl:strip-space elements="*"/>
<xsl:namespace-alias stylesheet-prefix="axsl" result-prefix="xsl" />
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="xsl:object[Time ='00000000']"/>
</xsl:stylesheet>
