Re: Error in spark-xml
Hi Sourav,
I think it is an issue. XML will assume the element by the rowTag as object.
Could you please open an issue in
https://github.com/databricks/spark-xml/issues please?
Thanks!

Re: Error in spark-xml

Can you try once by creating your own schema file and using it to read the XML.
I had similar issue but got that resolved by custom schema and by specifying each attribute in that.

Re: Error in spark-xml
Posted by Hyukjin Kwon <gu...@gmail.com>.
To be more clear,
If you set the rowTag as "book", then it will produces an exception which
is an issue opened here, https://github.com/databricks/spark-xml/issues/92
Currently it does not support to parse a single element with only a value
as a row.
If you set the rowTag as "bkval", then it should work. I tested the case
below to double check.
If it does not work as below, please open an issue with some information so
that I can reproduce.
I tested the case above with the data below
<root>
<bkval>
<book id="bk113">bk_113</book>
<book id="bk114">bk_114</book>
</bkval>
<bkval>
<book id="bk114">bk_114</book>
<book id="bk115">bk_116</book>
</bkval>
<bkval>
<book id="bk116">bk_115</book>
<book id="bk117">bk_116</book>
</bkval>
</root>
I tested this with the codes below
val path = "path-to-file"
sqlContext.read
.format("xml")
.option("rowTag", "bkval")
.load(path)
.show()
Thanks!
