With the Use PHP arrays option enabled in Workflow, the above HTML results in the following
XML:
<values count="4">
<user_account>[e-mail]</user_account>
<name>Peter Parker</name>
<company>Objectif Lune</company>
<pinElm1>
<pin_0>
<left>122</left>
<top>253</top>
<type>dent</type>
</pin_0>
<pin_1>
<left>361</left>
<top>341</top>
<type>dent</type>
</pin_1>
</pinElm1>
</values>
With the Use enhanced PHParrays option, the XML looks similar, but in this case, the value
between the first pair of square brackets is expected to consist of two parts, separated by an
underscore (e.g. row_0). The first part becomes the element's name. All content after the first
underscore (preferably an integer) is given as an attribute of the element (e.g. <row _idx=0>).
The above HTML results in the following XML:
<values count="4">
<user_account>[e-mail]</user_account>
<name>Peter Parker</name>
<company>Objectif Lune</company>
<pinElm1>
<pin _idx=0>
<left>122</left>
