[I sent this request earlier and my mail program stripped the html 
encoding. Here it is again, with the html encoding intact.]

Any suggestions on how do do the following?

Given the following DTD:

<!DOCTYPE test

[

<!ELEMENT test  (a1)+ >
<!ELEMENT a1    (b?, p, a2*) >
<!ELEMENT a2    (b?, p, a3*) >
<!ELEMENT a3    (b?, p, a4*) >
<!ELEMENT a4    (b?, p, a5*) >
<!ELEMENT a5    (b?, p, a6*) >
<!ELEMENT a6    (b?, p) >
<!ELEMENT b     EMPTY >
<!ELEMENT p     (#PCDATA) >
]>

And example instances 1 and 2:

Instance 1

<test>
	<a1>
		<p>Text of a1</p>
		<a2>
			<b/>
			<p>Text of a2</p>
			<a3>
				<p>Text of a3</p>
				<a4>
					<p>Text of a4</p>
					<a5>
						<p>Text of a5</p>
						<a6>
							<p>Text of a6</p>
						</a6>
					</a5>
				</a4>
			</a3>
		</a2>
	</a1>
</test>

Instance 2

<test>
	<a1>
		<p>Text of a1</p>
		<a2>
			<p>Text of a2</p>
			<a3>
				<b/>
				<p>Text of a3</p>
				<a4>
					<p>Text of a4</p>
					<a5>
						<p>Text of a5</p>
						<a6>
							<p>Text of a6</p>
						</a6>
					</a5>
				</a4>
			</a3>
		</a2>
	</a1>
</test>

I want each <p> in <a1>, <a2>, etc. to appear in an html <p> AND I want the 
indention for each <p> to be relative to where <b> occurred. For example, I 
want the following html output, where <b> occurs in <a2> in Instance 1.


		<p>Text of a1</p>
		<p>Text of a2</p>
		<p style='margin-left: 12px'>Text of a3</p>
		<p style='margin-left: 24px'>Text of a4</p>
		<p style='margin-left: 36px'>Text of a5</p>
		<p style='margin-left: 48px'>Text of a6</p>


And the following where <b> occurs in <a3> for Instance 2.


		<p>Text of a1</p>
		<p>Text of a2</p>
		<p>Text of a3</p>
		<p style='margin-left: 12px'>Text of a4</p>
		<p style='margin-left: 24px'>Text of a5</p>
		<p style='margin-left: 36px'>Text of a6</p>
