xml - XSLT: Splitting a string and doing something with each character -

i'm xslt newbie. i've gone through tutorials , i've been able 80% of want, xml document. however, stuck on something. in xml document, have attributes consist of values "era", "eda", "edar", , on. these attributes consist of combinations of letters e, d, a, , r. e, d, a, , r map edit, delete, add, , read.

if doing imperatively, split string component characters , check each character see if should output edit, delete, add, or read. how can similar in xslt? thinking of using length , substring functions , making loop of sort.

inline (or external) map:

<xsl:stylesheet version="1.0"  xmlns:xsl="http://www.w3.org/1999/xsl/transform"  xmlns:local="http://localhost">     <local:map letter="e" text="edit"/>     <local:map letter="d" text="delete"/>     <local:map letter="a" text="add"/>     <local:map letter="r" text="read"/>     <xsl:template match="test">         <xsl:copy>             <xsl:apply-templates              select="document('')/*/local:map[                         contains(current(),@letter)                      ]/@text"              mode="sequence"/>         </xsl:copy>     </xsl:template>     <xsl:template match="node()|@*" mode="sequence">         <xsl:value-of select="concat(substring(' ', 1 div (position()!=1)),.)"/>     </xsl:template> </xsl:stylesheet> 

output:

<test>edit delete add read</test> 

sequence of xsl:if instructions:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">     <xsl:template match="test">         <xsl:copy>             <xsl:if test="contains(.,'e')">edit </xsl:if>             <xsl:if test="contains(.,'d')">delete </xsl:if>             <xsl:if test="contains(.,'a')">add </xsl:if>             <xsl:if test="contains(.,'r')">read </xsl:if>         </xsl:copy>     </xsl:template> </xsl:stylesheet> 

output:

<test>edit delete add read </test>
