I want to update the value in XML based on attribute value using XSLT below is the Input and Output XML
In this example, I want to append hard-coded value in the input string.
<MyInfo isSurname="true">
<name sysid="0">Google</name>
</MyInfo>
<MyInfo isSurname="true" surname="Drive">
<name sysid="0">Google Drive</name>
</MyInfo>
For every input name surname will be same. so when the attribute isSurname is true we need to add "Drive" as surname
Let's put your Input XML in a root node as below:
<?xml version="1.0" encoding="UTF-8"?>
<Root>
<MyInfo isSurname="true">
<name sysid="0">Google</name>
</MyInfo>
</Root>
The solution in XSLT 1.0, can be:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="/Root/MyInfo">
<xsl:choose>
<xsl:when test="@isSurname = 'true'">
<xsl:copy>
<xsl:attribute name="surname">
<xsl:value-of select="'Drive'" />
</xsl:attribute>
<xsl:apply-templates select="@*|node()" />
</xsl:copy>
</xsl:when>
<xsl:otherwise>
<xsl:copy>
<xsl:apply-templates select="@*|node()" />
</xsl:copy>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="/Root/MyInfo[@isSurname = 'true']/name/text()">
<xsl:value-of select="concat(.,' Drive')" />
</xsl:template>
There's a check based on the isSurname attribute.
true, then the Output XML given by you will be populated.false, then the Input XML will be displayed as it is.This will work for your short example - not sure if those are the general rules you want to apply:
<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="*"/>
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="@isSurname[.='true']">
<xsl:copy/>
<xsl:attribute name="surname">Drive</xsl:attribute>
</xsl:template>
<xsl:template match="name[../@isSurname='true']/text()">
<xsl:copy/>
<xsl:text> Drive</xsl:text>
</xsl:template>
</xsl:stylesheet>
