[2005-07-26 18:19 UTC] pear at benbeaumont dot com

Description:
------------
If we put links in a record type node for an edge to link to, it doesn't work (e.g.:
$graph->addNode(
'struct1',
array(
'label' => '<f0> left|<f1> mid\ dle|<f2> right',
'shape' => 'record'
)
);

#this is taken from an example at http://www.graphviz.org/cvs/doc/info/shapes.html

This is because the output has \" in, when I removed them from lines 407,435 and 460, then it seems to work.

Test script:
---------------
<?php
$graph = new Image_GraphViz();

##example from graphviz.org @ http://www.graphviz.org/cvs/doc/info/shapes.html

$graph->addNode(
'struct1',
array(
'label' => '<f0> left|<f1> mid\ dle|<f2> right',
'shape' => 'record'
)
);
$graph->addNode(
'struct2',
array(
'label' => '<f0> one|<f1> two',
'shape' => 'record'
)
);
$graph->addNode(
'struct3',
array(
'label' => 'hello\nworld |{ b |{c|<here> d|e}| f}| g | h',
'shape' => 'record'
)
);
$graph->addEdge(
array(
'struct1:f1' => 'struct2:f0'
)
);
$graph->addEdge(
array(
'struct1:f2' => 'struct3:here'
)
);

#echo $graph->Parse();
$graph->image('jpg');
?>

Expected result:
----------------
Should have 3 record objects with links from within the objects to each other (e.g. from 'MId dle' to 'one' and 'right' to 'd') -- see the link to see the example.

Actual result:
--------------
There are more groups where the link names have been created as seperate nodes.
