Php validating xml

but sometimes, some customers send me an invalid xml and I want to return a good response. edited: Ok, I think I asked wrong question, I want to validate nodes and if some nodes missing then I return best response.

I used to validate this with php and I have to check every nodes. it is my xml example: You need to provide us: an example of correct XML (i presume the one you posted is valid), your DTD, an example (or more) of WRONG XML and the associated "best response". If you want to check only if the document is well formed (you don't care about the DTD validity, and don't even have a DTD to validate against) use Domdocument to validate your file, rather than XMLReader, because XMLReader will stream you document and don't load it at once, so is Valid() method will only check the first node.

As a result, typed XML data replaces previously untyped XML data. Load(reader) ' Make an invalid change to the first and last ' price elements in the XML document, and write ' the Xml Schema Info values assigned to the price ' element during load validation to the console.

To create an XML schema-validating Xml Reader, follow these steps. Dim manager As Xml Namespace Manager = New Xml Namespace Manager(document. Add Namespace("bk", " Dim price Node As Xml Node = document.

XML schema validation errors are reported when validating XML data loaded in the DOM.

Message) End Sub End Class files referred to in "Validating an XML Document as it is Loaded into the DOM" above.

I have made an api with xml based request for my website.The W3C XML specification states that a program should stop processing an XML document if it finds an error.The reason is that XML software should be small, fast, and compatible.The Xml Document class validates the XML data as it is loaded into the DOM when a validating Xml Reader is passed to the Load method of the Xml Document class. Create("contoso Books.xml", settings) ' The Xml Document validates the XML document contained ' in the Xml Reader as it is loaded into the DOM. After successful validation, schema defaults are applied, text values are converted to atomic values as necessary, and type information is associated with validated information items. Dim document As Xml Document = New Xml Document() document.
