Re: [topbraid-users] Generate XML output from SPARQL Web Pages File(.swp)

[Richard Cyganiak]

Hi Sanjeev,

As I said earlier: For ui:parse to work, its ui:str attribute must be a 
complete XML element, with opening tag, any child content, and closing tag. If 
ui:str is not a complete element (e.g., if it is only an opening tag or only a 
closing tag, as in getContinents.swp), then ui:parse will simply output the 
value of ui:str, without turning it into proper XML.

So, this will work because it’s a complete element with child content:

    <ui:parse ui:xml="true" ui:str="&lt;element&gt;content&lt;/element&gt;"/>

It will output: <element>content</element>

This won’t work, because it’s not a complete XML element (only an opening tag):

    <ui:parse ui:xml="true" ui:str="&lt;element&gt;"/>

It will output: &lt;element&gt;

So you need to assemble the entire XML element, including child content, as a 
single string variable, and then pass that as ui:str.

To generate the child content as a string variable, ui:bind/ui:stringify might 
be useful:
http://uispin.org/ui.html#bind

Here is an example:

    <ui:bind let:tagName="ParentElement">
        <ui:stringify ui:varName="content">
            <ChildElement value="xyz"/>
        </ui:stringify>
        <ui:parse ui:xml="true" ui:str="&lt;{= ?tagName }&gt;{= ?content 
}&lt;/{= ?tagName }&gt;"/>
    </ui:bind>

It will output:

    <ParentElement>
        <ChildElement value="xyz”/>
    </ParentElement>
