OIC XSLT: Execute Only When At Least One Field Has Value and None Are Blank

🔷 OIC XSLT: Validate Fields Before Executing Logic

🔹 Requirement

Fields: field1, field2, field3, field4, field5

✔ Execute only when: At least one field has a value

AND no provided field is empty (including spaces)

🔹 Final XSLT

XML

<xsl:if test="

(

  string-length(normalize-space(field1)) &gt; 0 or

  string-length(normalize-space(field2)) &gt; 0 or

  string-length(normalize-space(field3)) &gt; 0 or

  string-length(normalize-space(field4)) &gt; 0 or

  string-length(normalize-space(field5)) &gt; 0

)

and

(

  (not(field1) or string-length(normalize-space(field1)) &gt; 0) and

  (not(field2) or string-length(normalize-space(field2)) &gt; 0) and

  (not(field3) or string-length(normalize-space(field3)) &gt; 0) and

  (not(field4) or string-length(normalize-space(field4)) &gt; 0) and

  (not(field5) or string-length(normalize-space(field5)) &gt; 0)

)

">

   <!-- Execute logic -->

</xsl:if>

🔹 Key Idea (1 Line)

👉 Run only if:

At least one field has non-space value AND no field is empty/blank

🔹 Why normalize-space() Matters

Converts "   " → ""

Prevents false positives from whitespace

Ensures clean validation in OIC payloads

🔹 Quick Examples

Input == Result

<root/>❌ Skip

<field1>   </field1> ❌ Skip

<field1>ABC</field1> ✅ Execute

<field1>ABC</field1><field2> </field2> ❌ Skip
