xslt input control not setting base on data-CodePudding

I have this data that is being used with this xslt file that I can't get the Selected true to set the input radio to be checked. Is this the correct logic for checking test="Selected = true" to set that attribute?

Data

<CustomerGender>
      <CustomerGender>
        <Value>802</Value>
        <Text>Female</Text>
        <Selected>false</Selected>
      </CustomerGender>
      <CustomerGender>
        <Value>803</Value>
        <Text>Male</Text>
        <Selected>false</Selected>
      </CustomerGender>
      <CustomerGender>
        <Value>804</Value>
        <Text>Non-binary</Text>
        <Selected>true</Selected>
      </CustomerGender>
      <CustomerGender>
        <Value>805</Value>
        <Text>Prefer not to answer</Text>
        <Selected>false</Selected>
      </CustomerGender>
      <CustomerGender>
        <Value>806</Value>
        <Text>Other (please specify)</Text>
        <Selected>false</Selected>
      </CustomerGender>
    </CustomerGender>

XSLT

<div >
     <label >Gender</label>
     <div >
          <div >
               <label>
                    <xsl:for-each select ="Customer/CustomerGender/CustomerGender">
                         <input type="radio" name="selectedGender">
                              <xsl:attribute name="id" >
                                <xsl:value-of select="Value"/>
                              </xsl:attribute>
                              <xsl:attribute name="value">
                                <xsl:value-of select="Value"/>
                              </xsl:attribute>
                              <xsl:if test="Selected = true">
                                <xsl:attribute name="checked">"checked"</xsl:attribute>
                              </xsl:if>
                              <xsl:value-of select="Text"/>
                         </input>
                            &#160;&#160; <br />
                    </xsl:for-each>
               </label>
          </div>
     </div>
</div>

CodePudding user response：

The way your line

<xsl:if test="Selected = true">

works is:

The test is an xpath expression
Selected is an element name on the child axis
this part will return a nodelist containing all elements with name Selected
then it will test if the value is the same as the nodelist returned by 'true'

Not what you want. You could do something like

<xsl:if test="Selected = true()">
<xsl:if test="Selected">

it will test if the value is a boolean true
for this the nodelist has to be converted to boolean, which is true if the nodelist is not empty
since in none of your iterations there is a CustomerGender without Selected it will always be true

So you probably want to change that into

<xsl:if test="Selected = 'true'">

which will perform a string comparison. An alternative could be

<xsl:if test="Selected[1] = 'true'">

which will convert the first found element to string (resulting in the text content), then perform the comparison, or

<xsl:if test="Selected[1] = true()">
<xsl:if test="Selected[1]">

which would convert the first element into a boolean (and now I am lost myself...)
