[xml] Catch parsing error

[Tiberius Duluman <tiberius duluman iquestint com>]

Hello!

 

I’m using this code to parse an in memory XML:

 

[…]

    xmlParserCtxtPtr context = xmlNewParserCtxt();

    if (!context)

    {

        error = "Failed to allocate parser context";

        return;

    }

    xmlDocPtr doc = xmlCtxtReadMemory(

        context, xml, xml_size, NULL, NULL, 0);

    if (!doc && context->lastError.message)

        error = context->lastError.message;

[...]

 

When I parse the following invalid document:

 

<presence xmlns="urn:ietf:params:xml:ns:pidf" entity="sip:x x com">

    <tuple id="t1">

        <status>

            <basic>open</basic>

        </status>

</presence>

 

the error from context->lastError is

„Premature end of data in tag presence line 1”

but the one displayed on the screen is:

 

Entity: line 6: parser error : Opening and ending tag mismatch: tuple line 2 and presence

</presence>

           ^

Entity: line 8: parser error : Premature end of data in tag presence line 1

 

Why doesn’t the parser stop after first error is found?

How can I obtain the first error generated by the parser because it is more suggestive to

report to a user?

 

Thank you,

Tiberius
