SoapFault exception: looks like we got no XML document

Problem

A SOAP request fails with this error message:

looks like we got no XML document

Environment

• php-5.3

Solution

The error seems to indicate that although an XML document *is* sent, the XML is not valid according to the SOAP server's DTD or XML Schema.

Fortunately I have a working SOAP request, and by comparing the working request with the erroneous request, the cause appears to be a comma (,) instead of a period (.) inside an `xsd:decimal'.

In my case the WSDL shows the SOAP server is expecting an `xsd:decimal':

<xsd:element name="price" type="xsd:decimal"/>

and I'm sending a comma-separated price:

6,36

which should be period-separated:

6.36

Now the XML document is received all right :-)
