Hi,
I am trying to select all the nodes named querySubject from this following
XML:
<ResponseRoot xmlns="">
<folder _path="[CF_DEV]" _ref="[CF_DEV]" name="CF_DEV">
<querySubject _path="[CF_DEV].[Country]" _ref="[CF_DEV].[Country]"
datatype="0" name="Country">
<queryItem _path="[CF_DEV].[Country].[COUNTY_NM_EN]"
_ref="[CF_DEV].[Country].[COUNTY_NM_EN]" datatype="61" name="COUNTY_NM_EN"
usage="7"/>
<queryItem _path="[CF_DEV].[Country].[METRO_NM_EN]"
_ref="[CF_DEV].[Country].[METRO_NM_EN]" datatype="61" name="METRO_NM_EN"
usage="7"/>
<queryItem _path="[CF_DEV].[Country].[METRO_NM_FULL_EN]"
_ref="[CF_DEV].[Country].[METRO_NM_FULL_EN]" datatype="61"
name="METRO_NM_FULL_EN" usage="7"/>
<queryItem _path="[CF_DEV].[Country].[CTRY_NM_EN]"
_ref="[CF_DEV].[Country].[CTRY_NM_EN]" datatype="61" name="CTRY_NM_EN"
usage="7"/>
</querySubject>
<querySubject _path="[CF_DEV].[CF_ECON_EMPLY_FACT]"
_ref="[CF_DEV].[CF_ECON_EMPLY_FACT]" datatype="0" name="CF_ECON_EMPLY_FACT">
<queryItem _path="[CF_DEV].[CF_ECON_EMPLY_FACT].[Total
Population Count]" _ref="[CF_DEV].[CF_ECON_EMPLY_FACT].[Total Population
Count]" datatype="11" name="Total Population Count" usage="3"/>
<queryItem
_path="[CF_DEV].[CF_ECON_EMPLY_FACT].[POP_ECON_ACTV_CNT]"
_ref="[CF_DEV].[CF_ECON_EMPLY_FACT].[POP_ECON_ACTV_CNT]" datatype="11"
name="POP_ECON_ACTV_CNT" usage="3"/>
<queryItem _path="[CF_DEV].[CF_ECON_EMPLY_FACT].[POP_EMPLY_CNT]"
_ref="[CF_DEV].[CF_ECON_EMPLY_FACT].[POP_EMPLY_CNT]" datatype="11"
name="POP_EMPLY_CNT" usage="3"/>
<queryItem
_path="[CF_DEV].[CF_ECON_EMPLY_FACT].[POP_UNEMPLY_CNT]"
_ref="[CF_DEV].[CF_ECON_EMPLY_FACT].[POP_UNEMPLY_CNT]" datatype="11"
name="POP_UNEMPLY_CNT" usage="3"/>
</querySubject>
</folder>
<package name="CF_ECONOMICS"/>
</ResponseRoot>
I created a Document object like this:
SAXReader xmlReader = new SAXReader();
ByteArrayInputStream bais = new
ByteArrayInputStream(myXML.getBytes("UTF-8"));
Document d = xmlReader.read((InputStream)bais);
When I call d.selectNode("/ResponseRoot/folder/querySubject") or
d.selectSingleNode("/ResponseRoot/folder/querySubject"); - dom4j hangs and
freezes.
I can debug the thread, and in the stack trace, I see
NodeComparator.getDepth or NodeComparator.compare method calls at the top,
and control never returns from these functions.
If I modify the XML and only have 1 querySubject node under the folder node,
the calls to selectNode and selectSingleNode do NOT hang. So, how come
having 2 querySubject nodes under the folder node causes dom4j to hang? Can
anybody please explain what I am doing wrong?
Thanks,
-Richard.
