I have a DMN document that is using <![CDATA["text"]]> to represent string values. I am trying to all the words in an input string against one of the strings in these CDATA sections but I cannot figure out which XPath expression will do the trick.
Here is a sample DMN file:
<definitions xmlns="http://www.omg.org/spec/DMN/20151101/dmn.xsd" id="definitions_0fyde0d"
name="definitions" namespace="http://camunda.org/schema/1.0/dmn">
<decision id="decision" name="TroubleArea">
<decisionTable id="decisionTable">
<input id="input1" label="UserText">
<inputExpression id="inputExpression1" typeRef="string">
<text/>
</inputExpression>
</input>
<output id="output1" label="Subsystem" name="" typeRef="string"/>
<rule id="row-22012340-2">
<inputEntry id="UnaryTests_1hacpom">
<text><![CDATA["signal", "input", "connection"]]></text>
</inputEntry>
<outputEntry id="LiteralExpression_0wvuvyc">
<text><![CDATA["input"]]></text>
</outputEntry>
</rule>
<rule id="row-22012340-3">
<inputEntry id="UnaryTests_0cmpu76">
<text><![CDATA["screen"]]></text>
</inputEntry>
<outputEntry id="LiteralExpression_0hkc81e">
<text><![CDATA["output"]]></text>
</outputEntry>
</rule>
</decisionTable>
</decision>
The input is a single string, which needs to be matched against any string between quotes in the CDATA sections of <inputEntry> elements. When the match is found, I need to return the string in the <outputEntry> of the same <rule>.
After adding the namespace into my XSL, I can match the <decisionTable>, but I am still not getting any matches on any of the strings. Here is the code I am using to check if there are matches at all. This is not getting the <outputEntry> string yet, just "Yes" or "No" to tell me if there is a match at all.
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:dmn="http://www.omg.org/spec/DMN/20151101/dmn.xsd"
exclude-result-prefixes="xs"
version="2.0">
<xsl:output method="xml" encoding="UTF-8"/>
<xsl:param name="input"/>
<xsl:template match="/">
<result>
<xsl:variable name="table">
<xsl:value-of select="//dmn:decisionTable"/>
</xsl:variable>
<xsl:for-each select="distinct-values(tokenize($input,'%20'))">
<item>
<xsl:value-of select="."/>
<xsl:text>: </xsl:text>
<xsl:call-template name="matchrule">
<xsl:with-param name="text">
<xsl:value-of select="concat('"',.,'"')"/>
</xsl:with-param>
<xsl:with-param name="table">
<xsl:value-of select="$table"/>
</xsl:with-param>
</xsl:call-template>
</item>
</xsl:for-each>
</result>
</xsl:template>
<xsl:template name="matchrule">
<xsl:param name="table"/>
<xsl:param name="text"/>
<xsl:choose>
<xsl:when test="$table//dmn:rule[contains(dmn:inputEntry/dmn:text,$text)]">
<xsl:text>Yes</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>No</xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
Testing this with the input string "something%20with%20the%20screen%20or%20the%20screen%20brightness" gives the result:
result xmlns:dmn="http://www.omg.org/spec/DMN/20151101/dmn.xsd">
<item>something: No</item>
<item>with: No</item>
<item>the: No</item>
<item>screen: No</item>
<item>or: No</item>
<item>brightness: No</item>
I cannot change the DMN to not use those <![CDATA]> entries, as the table is created by another tool that I have no control over.
I think one way is to use
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xpath-default-namespace="http://www.omg.org/spec/DMN/20151101/dmn.xsd"
exclude-result-prefixes="xs"
version="2.0">
<xsl:output method="xml" indent="yes" encoding="UTF-8"/>
<xsl:param name="input">something%20with%20the%20screen%20or%20the%20screen%20brightness</xsl:param>
<xsl:template match="/">
<result>
<xsl:variable name="rules" select="//rule"/>
<xsl:for-each select="distinct-values(tokenize($input,'%20'))">
<item>
<xsl:value-of select="."/>
<xsl:text>: </xsl:text>
<xsl:apply-templates select="$rules[inputEntry/text[contains(., concat('"', current(), '"'))]]"/>
</item>
</xsl:for-each>
</result>
</xsl:template>
<xsl:template match="rule">
<xsl:value-of select="outputEntry/text"/>
</xsl:template>
</xsl:stylesheet>
which outputs
<result>
<item>something: </item>
<item>with: </item>
<item>the: </item>
<item>screen: "output"</item>
<item>or: </item>
<item>brightness: </item>
</result>
