After I tracked the exception, found that the involid XML format is the real causes。
In JavaScript file oryx.debug.js, the DOM path such as:
<path id=\"sid-F69764C6-F731-4C02-B33E-5E69E807EEB5_1\" fill=\"none\" marker-end=\"url(\"#sid-F69764C6-F731-4C02-B33E-5E69E807EEB5end\")\" marker-start=\"url(\"#sid-F69764C6-F731-4C02-B33E-5E69E807EEB5start\")\" stroke=\"#585858\" stroke-linecap=\"round\" stroke-linejoin=\"round\" stroke-width=\"2\" d=\"M 30.3438 30 L 42 30 L 42 30 L 79.5 30\"/>
<path id="sid-09B8CE0D-D2C1-4AAE-820D-FC5DB9A5ADD4_1" d="M320.5868361054004 109.04748237269533L419.5713670195996 76.55408012730467 " stroke="#585858" fill="none" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" marker-start="url(#sid-09B8CE0D-D2C1-4AAE-820D-FC5DB9A5ADD4start)" marker-end="url(#sid-09B8CE0D-D2C1-4AAE-820D-FC5DB9A5ADD4end)"/>

has two attribute marker-start and marker-end contains below structure:

marker-start=\"url(\"#sid-F69764C6-F731-4C02-B33E-5E69E807EEB5start\")\"

Which means quotation marks contains quotation marks again, if  the XML string send to the server side for resolving, it will cause exception.
