Converting escaped markup to nodeset

[vaibhavp]

Hi,
I am new to coding in Xslt and am stuck up on a problem for a very long time.
I have to convert an xml file to html using xslt.
I am using javax.xml.trans form API for this.
The xml file i have contains data in the following format

<person>
<name>PERSON_NA ME</name>
<addressXML>
&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&ltstreet&gtSTR EETNAME&lt/street&gt &ltcity&gtCITYN AME&lt/city&gt
</addressXML>
</person>

ie.the xml contains another xml file as value in escaped markup format.
Now since the value of addressXML is a text i cannot xpath.

Is there any way i can convert this text to a nodeset so i can access the values inside it by using xpath.
Currently I am using sub-string after and sub-string before to extract data but this process is giving out of memory errors for large xml files.
I have tried extension functions but could not succeed.(May be i dont know the right way)
Please help, I have been stuck up with this for a long time.
Thank you.

you could store the output (which should be xml) in a variable and use that again. like

// I have no clue of java... so these are symbolic commands
inputXML = "original_xml_file.xml"
inputXSL = "first_transformation.xsl" // print out the escaped text as xml
outputXML = transform(inputXML, inputXSL)
writeToFile(outputXML, file_name)
input2XSL = "second_transformation.xsl" // does what you intended in the first place
output2 = transform(inputXML, input2XSL)

the first transformation is used to convert the escaped xml text into real xml.
the second transformation can now access parts of the result xml via the document() function while working on the original xml file.

(I hope that's not too complicated written)

of cause the easiest way would be to use unescaped xml, but I don't know where the escaped xml originates...

I was going to suggest something similar.

Parse the file as a string before loading it as XML and replace &gt; with > and &lt; with < and <?xml version="1.0" encoding="UTF-8"?> with nothing and you will have

<addressXML>
<street>STREETN AME</street>
<city>CITYNAM E</city>
</addressXML>

Is this how you were doing it before where you were having problems with it slowing down?

Thanks a lot for replying.
I have a doubt If i parse the file as a string, how do i do it.
I am not aware if to parse it through Java. or xslt.
I thought about the first post and got an idea from that.
Instead of creating a new xml file for that section and using document() function
How about using a similar two step transformation to convert the first xml to a clean new xml file. and use it to transform to html?
Will this be a good opion?.. Because i will avoid Java Overhead of creating a new file for each such tag i encounter
Thanks to both of you..

you can do that as well.

how does it come that you get the escaped xml? if it is possible to fix that, it'd be the best solution I can think of.

jkmyoung is imho the master/xml god of xsl:copy procedures. there are some recent threads which can help you with copy issues.
