SelectSingleNode throwing exception:

Hi,

 

I have following XML which I need to modify and invoke a http request

I need to select a node but I am getting "Namespace Manager or XsltContext needed. This query has a prefix, variable, or user-defined function." Error

I am trying to access the <CUSTOMER/> tag with following code:

 

requestXmlDocument.SelectSingleNode("/SOAP-ENV:Envelope/SOAP-ENV:Body/m:MT_MaterialSearchRequest/" + XmlNodeName.CUSTOMER).InnerText
                       = some value;

Please consider following tags before giving answer:

• <SOAP-ENV:Envelope

• <SOAP-ENV:Body

• <m:MT_MaterialSearchRequest

 

 

Following is the Xml:

[highlight=xml]

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<SOAP-ENV:Body>

<m:MT_MaterialSearchRequest xmlns:m="http://br.eu/tl/v2">

<CUSTOMER/>

<SALES_ORG/>

<DISTR_CHAN/>

<DIVISION/>

<SEARCH_RESULT_SIZE/>

<DEFAULT_SORTING/>

<RESULT_TYPE>R</RESULT_TYPE>

<REQ_DATE/>

<REQ_QTY/>

<SALES_UNIT/>

<SEARCH_PARAM_IN>

<AGG_SEARCH/>

<COMMERCIAL_CODE/>

<DESCRIPTION/>

<WIDTH/>

<SERIE/>

<RIM/>

<LOAD_INDEX/>

<SPEED_SYMBOL/>

<PATTERN/>

<TUBE_TYPE/>

<BRAND/>

<HIERARCHY/>

</SEARCH_PARAM_IN>

<VISIBILITY_ITEM_IN>

<ITEM>

<ITM_NUMBER/>

<MATERIAL idtype=""/>

<REQ_QTY/>

<SALES_UNIT/>

<REQ_DATE/>

</ITEM>

</VISIBILITY_ITEM_IN>

</m:MT_MaterialSearchRequest>

</SOAP-ENV:Body>

</SOAP-ENV:Envelope>

[/highlight]

 

I think I have to use XmlNamespaceManager, but I am not getting how do I use it in this case when there are following three tags in the xmldocument.

• <SOAP-ENV:Envelope

• <SOAP-ENV:Body

• <m:MT_MaterialSearchRequest

 

 

 

Thanks in advance,

Anup

Have you tried creating a XmlNamespaceManager and adding the relevant prefix to namespace mappings to it? Then use the overloaded version of .SelectSingleNode that takes this class as it's second parameter.
