Attribute entity parsing hack (2.70 KB, patch)
2012-01-02 09:51 UTC, Emmanuel Pacaud 		none Details | Review

Description nakamoto 2011-12-13 03:58:13 UTC 
While lasem parses entity named in body text correctly, it doesn't in attribute strings.

For exapmle, the mathml below is rendered correctly,

<mo>&lfloor;</mo><mo>&rfloor;</mo>

however, the one blow isn't. A warning is shown as :
Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()

<mfenced open="&lfloor;" close="&rfloor;"></mfenced>


The one below works.

<mfenced open="&#x230a;" close="&#x230b;"></mfenced>

Attribute entity parsing hack

In order to parse entities in attribute value, libxml parser should be given the XML_PARSE_NOENT option. Unfortunately, there is no API when using xmlSAXUserParseMemory.

Here's a hack that enables entity parsing in attribute values.
Comment 2 nakamoto 2012-01-02 13:27:41 UTC 
Are you going to incorporate the patch into th main trunk ?
Comment 3 Emmanuel Pacaud 2012-01-02 13:45:39 UTC 
I'm not sure yet. It depends on the answer to the blocking bug 667118.
Comment 4 André Klapper 2012-04-04 10:19:30 UTC 
Mass-fixing incorrect QA contact scheme for lasem so interested people can
follow its development. (See 580127#c1 for ref.)
