The primary schema declaration looks like this on-disk: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; elementFormDefault="qualified" attributeFormDefault="unqualified">
It's updated in-memory to this: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; xmlns="http://www.company.com/schemas/servermain"; elementFormDefault="qualified" attributeFormDefault="unqualified" targetNamespace="http://www.company.com/schemas/servermain";> To do so, I load the schema and: 1.) xmlDocGetRootElement 2.) xmlSetProp with "targetNamespace" 3.) xmlSetProp with "xmlns" Is this the wrong way to go about this? Should I be using the NS-specific API's for step 3? The import nodes that I am adding look like this: <xs:import namespace="http://www.company.com/schemas/simulator"; schemaLocation="file:///home/pcameron/shared/debug/bin/schemas/simulator.xsd "/><xs:element name="Project"> One indication that something may be amiss is the way that the first <xs:element> is dumped without spacing (the rest of the doc is spaced/indented correctly with xmlDocDump). The following steps are used to create these nodes: 1.) xmlDocGetRootElement 2.) xmlFirstElementChild (I need to insert <xs:import> as the first child of <xs:schema> 3.) xmlNewNode with "xs:import" 4.) xmlDocCopyNode to populate the new node with doc info 5.) xmlAddPrevSibling to insert the new node in front of the previous first-child-element. 6.) xmlSetProp with "namespace" to setup the namespace attribute 7.) xmlSetProp with "schemaLocation" to setup the file URI for the import schema Finally, the imported schemas (which are not manipulated in-memory) have declarations that look like this: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; elementFormDefault="qualified" attributeFormDefault="unqualified" xmlns="http://www.company.com/schemas/simulator"; xmlns:simulator="http://www.company.com/schemas/simulator"; targetNamespace="http://www.company.com/schemas/simulator";> So, does anything seem blatantly incorrect here?
