I have a Data Flow task with an XMLSource that references an XML Variable. The DataFlow task does recognize that there are x number of rows in the variable, but it only sees null values in every row:
The xml variable value:
<?xml version="1.0" encoding="utf-8"?>
<words>
<word>butter</word>
<word>crispy</word>
</words>
I used this source to generate the XSD within the XMLSource Editor - here is the auto-generated XSD:
<?xml version="1.0"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="words">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="unbounded" name="word" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
The package compiles, exec开发者_如何学JAVAutes, and processes all the rows in my XML, but only sees nulls rather than the actual text strings... Here is a shot of the DataViewer displaying 2 rows after reading the XML variable:
I discovered a way to get the values to populate... I'll post it here without giving myself points, in case anyone else encounters the same problem. This is just a "how to fix", but I'll give credit to anyone who can explain the "deeper whys".
Essentially, the XML needed to be wrapped in another root node:
<?xml version="1.0" encoding="utf-8"?>
<datarows>
<words>
<word>bacon</word>
<word>roasted</word>
<word>pork</word>
<word>edamame</word>
</words>
</datarows>
Even though the original XML I used was valid, SSIS wanted it to be wrapped in an additional root node, which I named datarows. Once I did that the package recognized the word values and completed successfully.
The associated schema:
<?xml version="1.0"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="datarows">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="1" name="words">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="unbounded" name="word" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
I too had the same problem,. I was trying to consume a web service and import the output xml into a table in sql 2008.
The issue is really with the namespace that gets generated in the output xml by the webservice. The trick I have used was
1. Stored the output of the web service in a package level variable
2. Add a 'script task', to replace the unwanted name space.
3. Then used 'XMl Source Task' to import the data into a table.
