Question

<Person>
<AdditionalAttributes groupLabel="Profile">
<AdditionalAttribute name="First Name" value="John"/>
<AdditionalAttribute name="Last Name" value="Smith"/>
</AdditionalAttributes>

<AdditionalAttributes groupLabel="Additional">
<AdditionalAttribute name="email" value="John Smith(jsmith)"/>

Can you show me how to use xslt to add @gmail.com to value of element email from John Smith (jsmith) to John Smith(jsmith**@gmail.com**) assuming email value is dynamic

thanks and regards

Answer 1

XSLT 1.0 ，可以使用translate和concat ，不需要xslt ，只需使用普通的xpath 。

//Person/AdditionalAttributes/AdditionalAttribute[@name='email']/concat(translate(@value, ')', '@'), 'gmail.com)')

Answer 2

Try:

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="*"/>

<!-- identity transform -->
<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="AdditionalAttribute[@name='email']/@value">
    <xsl:attribute name="value">
        <xsl:value-of select="substring-before(., ')')"/>
        <xsl:text>@gmail.com)</xsl:text>
    </xsl:attribute>
</xsl:template>

</xsl:stylesheet>

This is assuming there are no closing parentheses other than the last one. Alternatively, you could do:

<xsl:template match="AdditionalAttribute[@name='email']/@value">
    <xsl:attribute name="value">
        <xsl:value-of select="substring(., 1, string-length(.) - 1)"/>
        <xsl:text>@gmail.com)</xsl:text>
    </xsl:attribute>
</xsl:template>

Added:

Can you also show me how to replace "John Smith(jsmith)" with "jsmith@gmail.com"?

Extract the text in parentheses and append the domain name to it:

<xsl:template match="AdditionalAttribute[@name='email']/@value">
    <xsl:attribute name="value">
        <xsl:value-of select="substring-before(substring-after(., '('), ')')"/>
        <xsl:text>@gmail.com</xsl:text>
    </xsl:attribute>
</xsl:template>

Answer 3

I. XSLT 1.0

Similar to the solution of michael.hor257k, but using AVT s -- Attribute-Value Templates.

Thus no need for an <xsl:attribute> operator :

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

  <xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="AdditionalAttribute[@name='email']">
    <AdditionalAttribute name="email"
        value="{substring-before(@value, '(')
                }({substring-before(
                             substring-after(@value,'('),
                             ')'
                                    )}@gmail.com)">
      <xsl:apply-templates select="@*[not(name()='value')]"/>
    </AdditionalAttribute>
  </xsl:template>
</xsl:stylesheet>

When applied on the provided XML document :

<Person>
    <AdditionalAttributes groupLabel="Profile">
        <AdditionalAttribute name="First Name" value="John"/>
        <AdditionalAttribute name="Last Name" value="Smith"/>
    </AdditionalAttributes>
    <AdditionalAttributes groupLabel="Additional">
        <AdditionalAttribute name="email" value="John Smith(jsmith)"/>
        <AdditionalAttribute name="Created Date" value="2016-04-20T19:50:01Z"/>
    </AdditionalAttributes>
</Person>

the wanted, correct result is produced :

<Person>
   <AdditionalAttributes groupLabel="Profile">
      <AdditionalAttribute name="First Name" value="John"/>
      <AdditionalAttribute name="Last Name" value="Smith"/>
   </AdditionalAttributes>
   <AdditionalAttributes groupLabel="Additional">
      <AdditionalAttribute name="email" value="John Smith(jsmith@gmail.com)"/>
      <AdditionalAttribute name="Created Date" value="2016-04-20T19:50:01Z"/>
   </AdditionalAttributes>
</Person>

II. XSLT 2.0

This transformation uses AVT again and the XPath 2.0 replace() function:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

  <xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="AdditionalAttribute[@name='email']">
    <AdditionalAttribute name="email"
        value="{replace(@value, '\)', '@gmail.com)')}">
      <xsl:apply-templates select="@*[not(name()='value')]"/>
    </AdditionalAttribute>
  </xsl:template>
</xsl:stylesheet>
