Hi,

I have a requirement where I need to validate the xmls that are getting generated by an application if it is well formed or not.

If it has generated incomplete xml (such as missing tags), then I need to correct it using some UNIX commands and have to process it.

I even gone through xmllint tool, but I could not understand how and what exactly it works and also could not understand how to use it.

Could anyone please help on this?

My XML look like below

<?xml version="1.0" encoding="utf-8"?>
<ProductInformation WorkspaceID="afjeqoe">
  <Qualifiers>
    <Qualifier ID="1">
      <DimensionPointLink DimensionPointID="eng"/>
    </Qualifier>
    <Qualifier ID="2">
      <DimensionPointLink DimensionPointID="std.lang.all"/>
    </Qualifier>
    <Qualifier ID="3">
      <DimensionPointLink DimensionPointID="USMarket"/>
    </Qualifier>
    <Qualifier ID="Qualifier root"/>
  </Qualifiers>
  <UnitList>
</ProductInformation>

Assuming your XML document is called output.xml, here is what xmllint outputs:

xmllint output.xml
output.xml:16: parser error : Opening and ending tag mismatch: UnitList line 15 and ProductInformation
</ProductInformation>
                     ^
output.xml:17: parser error : Premature end of data in tag ProductInformation line 2
