Github user HyukjinKwon commented on the issue: https://github.com/apache/spark/pull/17826 Hi @cloud-fan and @brkyvz, just while checking related issues with it just for my curiosity, I just realised that we are throwing an exception in XML related expressions as below: ```scala scala> sql("SELECT xpath_string('<a><b>b</b><c>cc</c></','a/c')").show() ... java.lang.RuntimeException: Invalid XML document: org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 23; XML document structures must start and end within the same entity. <a><b>b</b><c>cc</c></ at org.apache.spark.sql.catalyst.expressions.xml.UDFXPathUtil.eval(UDFXPathUtil.java:72) at org.apache.spark.sql.catalyst.expressions.xml.UDFXPathUtil.evalString(UDFXPathUtil.java:81) at org.apache.spark.sql.catalyst.expressions.xml.XPathString.nullSafeEval(xpath.scala:186) ... ``` Should we fix these expressions too or just leave them out for now?
